Principal Platform Engineer, AI-Driven Medical Infra

Neko Health AB; Greater London; On-site; GBP 140,000 - 200,000; Full time

Job summary

Neko Health AB is seeking a director-level Principal Engineer to build the shared AI engineering platform that enables rapid, compliant AI-driven software development for regulated medical devices. You will define architecture, set governance, and lead end-to-end AI-enabled engineering across teams, including devices and test rigs.

This senior individual contributor role requires shaping the fastest path to shipping with AI, ensuring auditability, traceability, and compliance while collaborating

Qualifications

• You have designed and built platforms or core infrastructure that other engineers relied on every day, and you wrote a meaningful part of the code yourself.
• Deep backend and distributed systems experience in production, with the judgement to make architecture calls in a large, existing codebase.
• Your own engineering is AI‑first: you use agents for work you used to do by hand, and can explain where they help, where they fail, and what changed in speed and quality.
• You take a clear position on hard technical questions with incomplete information, defend it with reasons, and change it when the evidence changes.
• Engineers outside your own team changed how they work because of something you built and the technical case you made for it.
• Able to work from our London, New York or Stockholm office.

Responsibilities

• 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 what changes with numbers engineers trust, such as the share of agent pull requests that get merged and how long a change takes to reach production, and share them openly
• Take on the hardest cross‑team technical problems, inside and beyond the platform, where no one has the answer yet
