Senior Full Stack Engineer

About the role

This is a Senior Full Stack Engineer opportunity with a New York virtual healthcare company whose mission is to make high-quality healthcare accessible to everyone, wherever they are. The role joins a team of five full-time engineers and works closely with the founder and CEO. The focus is iterating on an early-stage product so it can scale, and the role may grow into leadership over time. You’ll build across front-end and back-end, take part in or lead system architecture and DevOps decisions, attend daily standups and weekly sprint meetings, and deliver against an aggressive product roadmap. The posting names TypeScript and a modern tech stack without listing further tools. The ideal candidate will have 3+ years of engineering experience at an early-stage, high-growth startup, though the posting also states a preferred range of 1 to 5 years, so the seniority bar is unclear. Strong TypeScript experience, an ownership mindset and comfort in a fast-paced environment are expected. This is an on-site role in New York City, in person four days a week, with no remote or hybrid option stated. Note that the posting dates from September 2025, so confirm it is still open. We're looking for someone curious, pragmatic, and eager to work across the stack with a small senior team. You'll own end-to-end delivery of major features, influence architecture, and mentor engineers.

What you'll do

• Ship customer-facing features on a weekly cadence.
• Partner with design and product on scoping and trade-offs.
• Drive technical quality through review, testing, and docs.
• Mentor one or two engineers on your team.
