About The Position

As a Full Stack Software Engineer, you’ll build end-to-end product experiences across Aviator’s patient-facing app and internal AviatorOS, shipping everything from polished UIs to scalable APIs and integrations that power real care coordination. You’ll also help productionize our agentic and automation layer by building tool-using agents, workflow orchestration, evals, and safe human-in-the-loop controls so AI can reliably handle high-stakes operational work. This is a high-ownership role for someone who thrives in a fast-moving startup, loves turning messy real-world workflows into simple software, and ships quickly without compromising reliability. This role is in person in New York City, 5 days / week.

Requirements

3+ years of full-stack experience with a strength in backend systems (Python/TypeScript, Postgres, APIs/SDKs) and are comfortable jumping to frontend when needed.
A strong product sense and design intuition - you care about usability, polish, and user delight, not just functionality.
Familiarity with agent frameworks, automation tools, and AI-driven systems.
Deep comfort building with AI tools, including structured outputs, tool calling, retrieval patterns, and handling uncertainty safely.
Have high agency: you can set direction, make judgment calls, and drive projects forward without waiting for perfect clarity.
Have a strong sense of ownership and bias toward action.
Have shipped 0→1 products in a startup or fast-paced environment.
Can drive projects independently, with high accountability without much outside input.
Communicate clearly in writing: PR descriptions, docs, and Slack updates keep the team in sync.
Are adaptable and able to dive into unfamiliar systems, learn quickly, and make sound technical decisions.
Enjoy collaborating with a small, ambitious team in a fast-paced environment.
Are excited to work 5 days a week in our New York HQ (or open to relocating here).
Have a BS, MS in Computer Science or related field

Help define, scope, and review key projects; prioritize roadmap objectives; and sequence our deliverables.
Contribute to architectural decisions and engineering best practices as the company grows.
Implement monitoring, testing, and quality assurance to ensure consistent, reliable performance.
