About the role
We are searching for a Senior Fullstack Engineer to join a fast-growing Series A health technology startup focused on an innovative at-home monthly blood testing and health insights platform. This company has raised over $24 million across three funding rounds, with its latest round in November 2025. Their main product is an easy, painless at-home kit for collecting your own blood sample. Your results appear in a private, HIPAA-compliant dashboard where you can track your biomarker changes over time and understand their implications for your health.
The Tech Stack:
* TypeScript end-to-end * Express + React Router 7 (web) * tRPC * React Native (mobile) * React Query * Postgres + Redis
What You’ll Do: * Own features end-to-end — from design discussion to production rollout and monitoring. * Ship TypeScript on the web app, Node/Express backend, and/or mobile app. * Design and build fault-tolerant, HIPAA-compliant services with a strong focus on privacy, security, and stability. * Document your work so others can move fast. * Use the latest AI tools and SDKs to build AI-enriched features.
You’re a great fit if you… * Bring 6+ years of hands-on software experience, with advanced TypeScript skills. * Are comfortable working in a fast-paced startup where procedures aren't clearly defined. * Have built some great things you can show us and describe in detail. * Manage your own time, break down ambiguous problems, and deliver. * Use AI tools as an accelerator—never as the decision-maker. * Understand backend design and data modeling in SQL/Postgres. * Have written reliable tests with Vitest, Cypress, Jest, etc.
You’re an excellent fit if you… * Have used AI SDKs (AI SDK, OpenAI, Anthropic, etc.) with production software. * You have built or maintained HIPAA-compliant or other regulated healthcare software. * Are comfortable with internal tooling (e.g., Retool) and thorough documentation habits. * Bring deeper expertise in React Native or sophisticated systems architecture. * Are comfortable with monorepos.
What They Offer
* Salary: $160k – $210k * Equity: 0.05 % – 0.25 % * Benefits: Health, Dental, Vision * Time Off: Flexible PTO * Work Setup: Fully remote
This is a Senior / Staff level role. It is fully remote within the U.S. only.
