Netrin is a sports technology company building products that improve fitness, lifestyle, and performance. We're now building a D2C product (pre-product stage) at the intersection of health data and AI. If you have strong Python and AWS fundamentals, enjoy owning backend systems end-to-end, and want to be one of the first engineers shaping something new — this could be the perfect opportunity for you.

We're looking for a Principal Engineer architecting and building the Python backend, owning the AWS infrastructure and DevOps, and setting the engineering bar as we grow from a stealth founding team. You'll be one of the first engineers and the technical anchor for the system — shaping the architecture, not inheriting it. The platform integrates LLM services, so comfort working alongside AI components is a plus, but the core of this role is rock-solid backend engineering and production infrastructure ownership.
