Senior Full Stack Engineer

About the role

This is a Senior Software Engineer (Fullstack) opportunity with an early-stage New York company building AI agents for healthcare front offices, handling patient requests and documenting results in the EHR. The role leads deployment, performance and reliability of agents in live healthcare settings. You’ll architect full-stack systems that integrate with EHRs and real-time voice infrastructure, set technical strategy for customer-facing solutions, mentor engineers, and set standards for testing, security and HIPAA-compliant development. You’ll also influence the product roadmap. The stack is Node.js, TypeScript, React and PostgreSQL, with LLMs and real-time voice (with a 99.99% uptime target). The ideal candidate will have 5+ years building production systems in high-reliability environments, strong full-stack and system design skills, and proven mentorship and cross-functional leadership. This is an in-person role in New York City. 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.
