Despite the significant growth ecommerce has seen over the past few years, more than 80% of purchases still happen offline. Which presents a problem for real-world businesses that have no way to connect their online marketing investments with in-store results. Without a way to measure results, brick-and-mortar merchants are operating decades behind their online counterparts. We created Adentro to level the playing field. Online merchants use a digital cookie to close the loop from impression to purchase with key metrics like the click-through rate. Adentro gives merchants with physical locations the same transparency, allowing them to measure the effectiveness of their online marketing with the Walk-Through Rate. By understanding the bottom-line impact of their marketing, they can make smarter decisions and run more successful businesses

We previously built, launched, scaled and exited Parse.ly, a digital analytics platform, that processed &gt;1B events/day for 100s of customers.

Solve customer problems end-to-end. You’ll be given entire feature areas to implement from start to finish as well as smaller enhancements. Requests are often ambiguous and you’ll have to explore solutions before implementation. But, you won’t do this alone! You’ll have customers and a very supportive team as a sounding board for ideas and directions.
Fix bugs and support our customers.
Scale as we grow. We’ll proudly admit to doing some “things that didn’t scale” in our early releases to derisk something or try to immediately help a customer. As we scale, we’ll need smart and practical solutions that solve for our forecasted needs. Scaling applies equally well to technical solutions as well as process. We seek the minimal amount of process for a given stage of growth.

We acknowledge that skills and potential often extend beyond a checklist. If you don't check all of these boxes, but have gone deep in one of these areas then we strongly encourage you to apply. We believe diversity in skills fosters innovation, growth, and a more dynamic team environment.

5+ years experience building web apps with a preference for either frontend or backend development.
Backend development experience in Python, Typescript or RoR; Python preferred
Deep experience building production applications with one or more of: Django/Flask/FastAPI and React/Vue/Svelte.
Experience in data modeling (bonus: you’ve had experience with both relational and non-relational databases).
Experience in seeing a product or major feature from inception to production delivery.
Experience provisioning infrastructure to support features (you’re not expected to be a DevOps engineer, but we do expect some base knowledge around provisioning).
Extremely strong written communication skills (critical for a remote team).
Solid understanding of modern software development lifecycle processes (we use continuous integration and delivery to release multiple times a week)

Champify surfaces when previous customers, champions, and users change jobs - so you can build pipeline, increase win rates, and expand with people who already love your service, and prevent churn by monitoring when key contacts leave and join customer accounts.

About Champify

Champify is building the future of B2B revenue generation - a platform for Sales Intelligence that helps sales and marketing teams leverage pre-existing warmth to build new pipeline and strengthen customer relationships.

B2B revenue growth is changing - no longer can teams rely on mass cold outreach to strangers. It’s crucial to find and prioritize warm relationships.

By combing through and interpreting first-party, third-party and public data sources, Champify surfaces crucial context on the people that buy and use your software so that sales and marketing can drive efficient and sustainable growth.

You'll help us expand our product offerings, both with additional development for our enterprise functionality, and crafting our product led growth engine.

We're looking to bring on a full-stack startup engineer with shipping experience across the entire web development stack (HTML/CSS/JS + any backend). Most importantly, you should have a proven ability to turn ideas into reality.

We believe cold outbound is dying and sellers aren’t working efficiently. Our first product, Champify Track, helps revenue teams by surfacing job changes in Salesforce. This helps customers focus on existing relationships instead of sending emails to and cold-calling uninterested, new prospects. We’ve introduced multiple products in just the last 6 months: Calendar Sync, Exec Arrivals, Referrals, and have plans to release many more in the coming months.

The customers in our target market are seeing that the old ways of prospecting new business and selling to customers (e.g., mass emailing cold contacts) simply do not work. This is why it’s so important that you have the interest and ability to jump into a new problem space, absorb the key facts, and propose creative ideas. Past experience is less important to us than the will to challenge yourself and grow.

Our backend runs on Node.js, TypeScript, PostgreSQL, and Prisma. Our customer-facing product runs inside of Salesforce as a managed Apex application. Experience with any of these technologies or tools is a plus, but not required.

Responsibilities:

• Iterate, improve, and expand our existing product suite
• Define the culture and best-practices of our engineering team
• Interview, onboard, and mentor future engineers

Qualifications:

• You've shipped products in the context of a small team and know how to move fast
• You enjoy talking to users, understanding their problems, and designing solutions that they'll clamor for
• You seek out challenges and aren't afraid to stretch your comfort zone
• You've worked with a variety of technologies (on both the frontend and backend)
• You’re familiar with- software development practices such as CI/CD, version control, code review, etc.
• Bonus: You have sales tech, CRM, or data acquisition product experience

SOOT is a new way of mapping information. It’s self-organizing, spatial, and incredibly fast. For mapping design files, videos, websites, and moodboards.

About Soot

Requested Intros
Looking for a frontend web engineer with experience in web graphics, or a graphics engineer with experience in frontend systems.

Technical Details

Our frontend tech stack is composed of Vue.js, THREE.js, WebGL (2.0), GraphQL, and TypeScript. We make heavy use of modern web technologies including canvas and web workers. You don't need to be familiar with ALL of these technologies, but you'll probably struggle without some experience with at least two of these.

The SOOT frontend pipeline is responsible for rendering tens of thousands of unique pieces of data quickly while maintaining a high quality user experience and a high quality design-experiment environment. This means an intense focus on speed, scale, and extensibility. Much of the role is focused on developing coherent abstractions for the difficult rendering problems, while building out the UX for an incredibly talented design team.

Prior Technical Experience That We Look For

Web engineering – in particular, experience designing component systems and working closely with designers / product managers.

Game engineering (NICE TO HAVE) – in particular, thinking about and implementing novel UX patterns without 'closing doors' to future exploration, coming up with coherent user interaction states and that can support a huge range of UX flows


Distributed systems engineering – in particular, experience with thinking about data lifecycles, inter-process communication, and effective data structure design

Other Things We Look For
SOOT is a small startup, everyone wears a lot of hats. So we're looking for folks who are capable of programming in diverse settings. We're keeping an eye out for projects in multiple languages/paradigms/frameworks, potentially with different build systems and tooling setups (gradle, npm, pip, Make), deployed in multiple settings (web, cloud, embedded systems, mobile).

We love folks who have opinions that are borne out of experience, including non-technical ones. We're keeping an eye out for technical and non-technical writing, presentations, and PRs, issues, and conversations in public repositories and forums.
 
Because we're a small team, we expect a lot of autonomy and independence. We're keeping an eye out for folks who have prior experience building out their own projects, or who have prior startup experience or personal consulting experience. Really any role where you have to deal with a lot of ambiguity and turn it into something magical.

And finally, we're looking for folks who will be excited to be with and grow with SOOT in the long run :)

Soot

SOOT is seeking a Backend Engineer to help build and scale oucutting-edge spatial file system, designed to transform digital file management into an immersive experience. The role focuses on developing and maintaining a high-speed, high-availability backend using AWS, Node.js, Python, and various ML tools.

Our backend tech stack is built on AWS, managed with terraform. We deploy several node (typescript) and python binaries through ECR and K8s. The binaries communicate with each other using SQS, and store data to a S3 blob store and DocDb data store. We depend on ML tooling (primarily Torch, but increasingly higher level libraries like langchain, huggingface), and we make heavy use of OpenSearch. We utilize an event-sourcing model to support multiplayer and sharing.  

You don't need to be familiar with ALL of these technologies, but you'll probably struggle without some experience with at least a few of these.

The SOOT backend is responsible for processing tens of thousands of unique pieces of data quickly while maintaining high availability to support a seamless frontend user experience. This means an intense focus on speed and scale, with an eye towards maximizing parallelism, such that the system can easily consume resources as they become available. The backend is also constantly growing in terms of feature complexity – we are rapidly bringing new features online, all of which support step function improvements to SOOT.

Much of the role is about developing coherent abstractions and thinking about data lifecycles. The SOOT backend is responsible for managing a lot of widely varying behaviors, from ML processing to data compression to basic CRUD. To support all of this while ALSO growing our feature list, we heavily focus on reducing complexity.

Prior Technical Experience That We Look For:
 
Distributed systems engineering – in particular, experience with thinking about data lifecycles, inter-process communication, and effective data structure design

Database engineering – in particular, experience with maximizing speed for specific high value queries at a system level, scaling to efficiently utilize available resources, and dealing with weak data consistency guarantees 

Real-time Multiplayer (NICE TO HAVE)– in particular, dealing with concurrent document editing. Heavy preference for folks who have experience with multiplayer servers for video games, but any experience here (including OT or CRDT) is fantastic

Other Things We Look For

SOOT is a small startup, everyone wears a lot of hats. So we're looking for folks who are capable of programming in diverse settings. We're keeping an eye out for projects in multiple languages/paradigms/frameworks, potentially with different build systems and tooling setups (gradle, npm, pip, Make), deployed in multiple settings (web, cloud, embedded systems, mobile).

We love folks who have opinions that are borne out of experience, including non-technical ones. We're keeping an eye out for technical and non-technical writing, presentations, and PRs, issues, and conversations in public repositories and forums.

And finally, we're looking for folks who will be excited to be with and grow with SOOT in the long run :)

Found is a modern weight care platform pioneering integrated support through personalized coaching, online community, and if indicated, prescription medication. We believe that weight care is complex and goes beyond having the willpower to eat less and move more. We believe in the power of biology, genetics, sleep, stress, mental health and daily habits and we work with each factor to achieve long-lasting results. Our goals are to address the long-term risks associated with ineffective weight management, to reimagine the narrow and outdated cultural narrative around weight, and to empower our community with tools that will help them find self-acceptance and add years to their lives. We believe it’s not just what you’ve lost, it’s what you’ve Found.

About Found

Found is a modern weight care platform and community focused on integrated support. According to a recent CDC study, nearly 50% of Americans want to lose weight, and on average, Americans have gained 30 lbs during the pandemic. But the existing weight loss industry focuses on shame - if you don’t have the willpower to eat less and workout more, you aren’t trying hard enough.
Modern science shows us that weight care is complex - food and movement are important, but so are hormones, genetics, sleep, stress, mental health, and daily habits. Found’s unique approach incorporates personalized coaching, an online community, and if indicated, medical and prescription solutions.
Research shows that addressing weight health reduces the long-term risk of diabetes, heart disease, and some forms of cancer. We believe in giving our community tools that will help them add years to their lives and reach their goals. We believe it’s not just what you’ve lost, it’s what you’ve Found.

The Opportunity
Found is looking for a Senior Product Designer eager to push the boundary of their craft and problem-solving skills. This role is for a specialist focused on growth. In this role you will:
● Drive conversion of new members across our end-to-end acquisition flow
● Design responsive mobile-first landing pages, purchase flows, account creation, and
checkout experiences
● Attract prospects to Found’s offering and help them realize when Found is right for them
● Deeply collaborate with marketing partners on strategy and experiment design
● Continuously partner with product and engineering to deliver and iterate on experiments
You’ll be reporting to the Director of Design and working alongside cross functional leaders in marketing. If you’re looking to join a team that is bringing award winning designs to a neglected industry and diving into ambiguity to identify and plan the next set of problems, we’d love to connect.

Open up our platform
You should expect to work on projects that help expand our TAM and make it easier and more enjoyable to access Found. This involves growth projects, AB split testing designs to drive conversion and retention, and allowing people to pay only for what they need.
Explore monetization
As we continue to expand our product line, you’ll have to distill complex inputs like insurance or medication eligibility into simple experiences that are easy to understand for prospective customers.
Represent customers
Being able to dive into data and defend the most important areas for us to focus our energy on must be a passion of yours.
Grow the voice of design
Inside and out, we want to bring on designers who love to teach, coach, and elevate the process of design thinking.

Expert at your craft
You dabble with all creative tools, but feel masterful in a few - particularly Figma and Webflow.You have demonstrable experience in driving acquisition through design. UX/UI, conversion, brand, typography, color, layout are your bread and butter. You can easily apply that knowledge to mobile, web and any other design domain you choose to play in. You can manage any level of chaotic Figma auto-layout nesting, and thrive at keeping design systems organized. You can prototype at any level of fidelity but know what needs to be used in order to get the right answers solved. You feel comfortable building workshops and leading research when needed.
Skilled at storytelling
You’re able to inspire, clarify, and teach through storytelling across all levels of leadership. You believe that content-strategy is just as important as the UI and have a strong portfolio of craft experiences beyond the pixels and helping people feel and believe in the Why behind what you’re building. You are comfortable explaining design decisions and tying them to business outcomes.
Tardigrade-level resilience
You have a strong background building products with ambiguous or uncertain problem definition and are able to navigate a team through the chaos with grace and direction. You’re able to demonstrate moments where you have been able to align differing ideas of what is right to the best solution as moments of letting things go in pursuit of progress despite not agreeing fully with the direction itself.

Bonus Points
● 5+ years in product design in complex organizations
● Background in graphic design or brand design
● Strong illustration skills
● Strong motion design skills
● Background in Blender or C4D
● Riding the wave of Stable Diffusion and OpenAI

About CollegeVine

CollegeVine is an AI company with a mission to bring lifelong guidance to the next generation. Facilitated by Sage, CollegeVineʼs AI advisor, the platform guides millions of students with personalized advice and actionable insights and empowers students to navigate their admissions journey proactively. Meanwhile, we are also transforming recruitment at colleges, universities, and other institutions. By leveraging advanced AI agents, proprietary data, and an extensive network of millions of high school students, CollegeVine enables these institutions to hyper-personalize their recruitment activities at scale and across multiple modalities.

As CollegeVine scales, we’re looking to add talented engineers focused on solving real-world problems to help us build new products and scale our existing systems. In particular, you'll work directly with CollegeVine's leadership to build new AI agents and equip CollegeVine's existing agents with new capabilities. On CollegeVine’s engineering team, each engineer owns their work from idea into production while focusing on pulling business value as early in our development process as possible. This means small batches, CI/CD, deploying to production multiple times per-day, and rapid iteration as our ideas become reality for our customers.

You’ll work on a product squad alongside designers, domain experts, and other engineers to solve the correct problems and deliver our guidance technology in a safe and reliable way.

This role is fully remote with a strong preference for candidates located in the US or Canada.

• Use the latest tools and research in applied machine learning, LLMs, and AI agents to enhance our products and create delightful user experiences
• Own problems end-to-end, deliver results quickly, and be willing to pick up whatever knowledge you're missing to get the job done
• Partner with subject matter experts across the company including security, product, design, and customer success
• Focus on solving the problems at hand, not just writing code (although that’s typically how CollegeVine delivers solutions)
• Hone your craft by writing performant and maintainable code to extend the CollegeVine platform by working in (at least) Purescript and Ruby

•8+ years of software engineering experience (including internships)
• Proficiency with relational databases, modern IasS platforms, (Javascript || Ruby), and MVC web frameworks like Ruby on Rails. We also make heavy use of Purescript, so experience or an interest in learning typed-functional programming is necessary.
• You see yourself first and foremost as a pragmatic problem solver who just happens to write code
• Have a humble attitude, a love for learning, an eagerness to help your colleagues, and a desire to do whatever it takes to make the team succeed
• Care deeply about the end user experience and take pride in building products to solve customer needs
