Principal Engineer - Platform

Job description

Mission Neko is redefining what prevention means, from treating illness when it arrives, to sustaining health before it's ever at risk. Our mission: make data-driven, preventative care accessible to more people, before symptoms appear. In a single, non-invasive visit under an hour, proprietary technology and direct clinical care combine to deliver personalised, actionable insights. It's a team that thinks in 10x, not 10%. Every role here plays a part in building a world where prevention is the norm, and where your work genuinely helps people live longer, healthier lives. Role Purpose We want our engineers to ship regulated medical software as fast as AI now lets them write it. Our software includes medical device software, holds members’ health data and keeps our clinics running, so every change has to be tested, traceable and ready for an auditor, and that is what makes this problem hard and worth solving. You’ll build the shared AI engineering platform that makes it possible, setting the architecture and writing much of it yourself: a golden path that makes the best way to build with AI the default for every team, agents that do real engineering work end to end, and a pipeline that proves compliance on every change instead of documents written after the fact. This is a director-level individual contributor role, one of the first Principal Engineer roles in our software organisation, working directly with our Chief Software Officer. You make the key calls on which agents and tools we build or adopt, and you take on the hardest problems across teams, some of which reach clinic devices and the test rigs that recreate a scan room. What You’ll Deliver in the First 6–12 Months 0→1 set the target architecture for the AI engineering platform, including the build or adopt decisions on agents, orchestration and developer tooling Ship a golden path for AI-assisted engineering, with shared context, tools and guardrails, that teams choose because it is the fastest way to ship Put agents to work on real engineering jobs end to end, such as feature implementation, code migrations, automated review and on-call triage Run agents in sandboxed environments with audit trails and clear separation from member health data Shorten the path from merged code to production for regulated software: safe releases, fast rollback, and compliance evidence produced by the pipeline Measure…
