About the role

- FOXO’s backend is where some of the most consequential work happens: biomarker results, personalized protocols, lab report parsing, and the business logic that connects health data to recommendations.

- This is not a ticket-closing role. You’ll work under a Lead Backend Engineer, but the product surfaces you own are yours to design, build, improve, and support in production.

- You’ll own the member-facing customer journey across backend systems, and if your profile is fullstack, you’ll also own selected web and internal tooling surfaces.

- This is a full time role for an engineer who wants meaningful ownership in a domain where correctness matters.

What you will build

- Member onboarding and profile APIs — the data layer for health goals, conditions, supplement history, and wearable devices.

- Lab report ingestion — receive parsed biomarker data from the extraction pipeline and normalize it into a member’s longitudinal health record.

- Protocol delivery APIs — build the endpoints that serve personalized supplement and lifestyle recommendations with strong correctness and low latency.

- Member progress and history — power longitudinal biomarker views, trend calculations, reference range evaluation, and alert thresholds used by clinicians and nutritionists.

- Notification and communication systems — scheduled reminders, protocol check-ins, and biomarker follow-ups that need reliable delivery at scale.

- If you’re fullstack, you’ll also build member-facing Next.js surfaces and internal ops tooling used by clinical and operations teams.





Tech stack

- Python, FastAPI, Supabase (PostgreSQL), GCP Cloud Run, pgvector, GitHub Actions, and Claude API (Anthropic).

- For fullstack work: Next.js, React, TypeScript, and Tailwind CSS.

- We use Supabase Row Level Security heavily, so you should be comfortable reasoning about access control and writing policies correctly around sensitive member data.

What we’re looking for

- 3–5 years of backend engineering experience building APIs that real users depend on, including handling production issues when things break.

- Strong Python fundamentals and a habit of writing clean, testable code.

- FastAPI or similar async framework experience with a real understanding of async behavior at runtime.

- Strong PostgreSQL skills across schema design, indexing, query optimization, and debugging slow queries.

- REST API design experience including versioning, change management, and designing endpoints other engineers consume.

- Frontend literacy is a plus — especially React or Next.js familiarity that helps in a small, fast-moving team.

- For fullstack candidates: production-level comfort across Python/FastAPI and Next.js/React, strong TypeScript habits,



and experience building internal tools or data-heavy interfaces.

- Across both profiles: you write pragmatic tests, can own a feature from schema design through deployment, and understand the basics of handling sensitive health data responsibly.

Green flags

- You’ve built a user-facing product journey such as onboarding, profile, or notifications and understand the full lifecycle.

- You’ve worked in health, fintech, or another regulated-data domain where correctness is non-negotiable.

- You’ve used an LLM API in production and understand token costs, reliability, and schema mismatches.

- You ask why before you build, and want to understand the real member experience behind the systems you design.

Why this role

- At many companies an SDE-2 owns a small slice of a feature. At FOXO, you’ll own a meaningful part of the member journey end to end.

- The team is small enough that your decisions compound. A strong data model or API decision you make today can keep paying off for years.

- If you want real product ownership, fast learning, and work where the details matter, this role is built for that.
