Technical Lead, Rust

About Helfie:

Helfie is on a mission to redefine global preventative healthcare. We're pioneering an entirely new operating system for human health – empowering billons with instant, affordable health checks and AI-driven insights. Our vision is to build trust, drive organic engagement, and make preventative healthcare a reality for all 8 billion of us.

Join us as we revolutionise the healthcare landscape and make early detection and prevention accessible to everyone.

About the role:

We're looking for a Rust-first Tech Lead who thrives on scale, impact, and purpose. In this role you'll own critical services end-to-end, design clean architectures, and write a bunch of code.

You'll set the bar for code quality and maintainability through thoughtful reviews, design patterns, and a pragmatic approach to optimization. You'll mentor engineers on complex programming topics (scalability, consistency, fault tolerance) while partnering with product, QA and architecture teams to turn tricky problems into elegant, well-tested solutions.

If you love squeezing milliseconds without sacrificing readability—and leaving a codebase better than you found it—this is your seat.

You'll join a high-performing, mission-driven team building applications that touch
millions
of lives — and scaling them to reach
billions
