## Job description

## About Fay

At Fay, our mission is to make nutrition a foundational pillar of preventative care, improving outcomes, accessibility, and affordability at scale. We're building AI-powered infrastructure to transform preventative healthcare. Think that's bold? We're just getting started.

Today, Fay is a three-sided marketplace connecting providers, patients, and payers to revolutionize preventative care delivery. Our b2b2c business-in-a-box solution empowers dietitians to deliver high-quality, affordable nutrition care, helps patients take control of their health, and enables payers to build healthier member populations. Nutrition is our starting point, not the finish line. The platform we're building will expand into new areas of preventative health and wellness as we grow.

We're proud to be one of the fastest-growing companies in healthtech, backed by category-defining investors like General Catalyst, Forerunner, 1984, and Goldman Sachs.

Ready to leverage AI-driven technology to transform preventative care and make a real-world impact on health? Let's talk.

## About this Role

This role offers what many ambitious engineers are looking for:

- 🌟 Top-tier teammates: We have an unusually talented and accomplished team of engineers who’ve held lead, staff, principal and director level roles in past jobs.
- 🧑‍💻 A builder-centric culture: We’re a fast-moving team with high standards, supported by thoughtful processes that keep things running smoothly without getting in the way.
- ⚒️ Modern tools & best practices: We use the best tool for the job at hand, and we’ve leaned into AI-driven development in all of the places it’s proven to be most effective.
- 🤝 A tight-knit, high-output team: We’re a total of nine backend/full-stack engineers who collaborate closely, move quickly and have an unreasonable amount of fun together.
- 🤲 An ever-important mission: We’re here to deliver high quality, convenient and affordable care to the hundreds of millions of Americans who need it.

Our software platform is well established and our user base is already quite large, but we’re still in the very early innings of building the world’s hub for healthy living. It will take more world-class engineers to bring our ambitious vision for Fay to life, and that’s why we’re hiring!

What You'll be Doing:

- Building features end-to-end: All engineers lead projects and take ownership of their delivery and impact.
- Contributing to the underlying platform: We all pitch in to keep the platform stable and the developer experience smooth.
- Supporting engineering teammates: We have lively engineering Slack channels and huddles where we run ideas by each other and problem-solve together.
- Teaming up with product & design: Every project is a team effort between engineering, product and design, and everyone involved pushes for the best outcome.
- Maintaining a high standard: We have a culture of doing things thoughtfully and doing them right, which comes with a commitment to uphold team best practices.
- Making the product your baby: We jump in to prototype our new feature ideas, remove developer pain points and fix nagging UI blemishes — all because we care about making things great!

Your Skills & Experience:

- Backend or full-stack — the more of a generalist, the better
- At least two years of professional experience and no experience cap — we’re hiring across all levels of seniority
- Enough familiarity with Python and TypeScript+React to confidently make code contributions on day one
- Clear communication and an eagerness to collaborate effectively across engineering, product and design
- Experience building user-facing products, with an eye for detail and a sense of what makes software feel intuitive and polished
- Comfort working in fast-paced, dynamic startup environments
- Strong ownership mindset: you care about the outcome, not just your piece of the implementation

The best companies are made of the best people. There’s no shortage of work ahead, but we stay balanced and look forward to celebrating our wins as a team.
