Principal Engineer

What You’ll Do

• Own architecture end-to-end: design, evolve, and document backend systems, APIs, and infrastructure.
• Stay hands-on: write production-grade code, contribute to design reviews, and drive technical excellence.
• Set engineering standards for testing, observability, CI/CD, and deployment practices.
• Partner with product and leadership to translate complex problems into clean, scalable solutions.
• Guide technical strategy and roadmap decisions to ensure we’re building with scalability, security, and simplicity in mind.
• Collaborate cross-functionally with mobile, design, and clinical stakeholders to deliver reliable and delightful user experiences.

What We’re Looking For

• 8+ years of experience building and scaling production systems.
• Deep experience in Python (FastAPI, Flask, or similar).
• Proven expertise with AWS serverless: Lambda, DynamoDB, EventBridge, API Gateway, S3, and related services.
• Strong understanding of distributed system design, data modeling, and cloud architecture best practices.
• Familiarity with React Native / Expo or mobile API integration patterns.
• A track record of technical leadership — setting standards, improving systems, and leading initiatives.
• Clear communicator who values pragmatism, iteration, and delivering great products quickly.

Bonus Points

• Experience designing new architectures from scratch or leading major refactors.
• Background in healthcare, privacy, or regulated environments.
• Experience with TypeScript, NestJS, or Node.js for edge or integration work.

Why You’ll Love It Here

This is a chance to build something that matters — with full ownership and creative license to shape the technical direction from day one. You’ll have the autonomy to choose the right tools, improve processes, and build systems that scale gracefully as we grow.
