Lead Software Engineer

Job Responsibilities:

You’ll be a core part of a high-trust team that builds mission-critical systems at breakneck speed. Expect real ownership, end-to-end product impact, and a seat at the architecture table from day one. In this role, you will:

• Build full-stack features across our three flagship products - Angular, Node.js, React, AWS (serverless).
• Own projects end-to-end, from product definition through backend/frontend, QA, deployment, and beyond.
• Collaborate closely with clinicians, ML researchers, and engineers to ship high-impact features in fast iteration cycles.
• Work with GraphQL APIs, reinforcement learning models, and real-world data pipelines to drive patient outcomes.
• Continuously improve developer experience, system stability, and CI/CD workflows.
• Join customer calls to deepen understanding of user needs and shape product direction.
• Drive engineering culture, mentor junior developers, and help scale the team’s impact over time.

Job Requirements:

• 5–15 years of professional experience as a full-stack engineer, with proven product ownership.
• Expertise in JavaScript/TypeScript, with strong command of Angular, React, and Node.js.
• Fluency with AWS serverless architecture: Cognito, Lambda, DynamoDB, AppSync, CloudFormation, etc.
• Experience building end-to-end products (not just infra or microservices), ideally at fast-scaling, VC-backed startups (Series A–C).
• Strong product sensibility - you're a T-shaped engineer who obsesses over both code quality and user experience.
• Long tenures (2+ years per role) with clear growth trajectory.
• Degree in CS or equivalent from a top-tier university (e.g. MIT, Stanford, CMU, ETH, Toronto, Oxford, etc.).
• Experience integrating GraphQL, ML models, or agentic AI systems.
• Background in healthcare, life sciences, or climate tech.
• Prior role as a founding engineer, CTO, or technical co-founder.
• Hacker mindset - relentless problem-solver, resourceful, autonomous.
• Mission-driven - deep desire to build for the real world and do work that saves lives.
• Thrives in high-intensity, ambiguous, and fast-paced environments.
• Cares about shaping engineering culture and empowering others.
