Platform Engineer - Build & CI

Team: Platform Software Location: UK, London Employment type: FullTime

Here at Humanoid, we believe in a future where robots amplify human potential. That’s why we’ve set out on a mission to build the world’s most capable, commercially-scalable, and safe humanoid robots. We’re bringing that mission to life with HMND‑01 Alpha - our rapidly developed humanoid platform now running in real industrial pilots - and we’re growing the team to take it even further.

ABOUT THE ROLE

We are looking for a Software Engineer to own the build system and CI infrastructure that every engineer at Humanoid depends on every day. This is foundational work: a slow, unreliable, or opaque build pipeline is a tax on the entire engineering organisation, and getting it right directly determines how fast we can ship robots.

We are investing heavily in build infrastructure - hermetic, incremental, fully cached builds across a complex multi-target monorepo spanning firmware, robot software, simulation, and cloud - and we need someone to drive that work and own the system it produces.

This is a deeply technical infrastructure role. You will work closely with every engineering team in the organisation, and the quality of your work will be felt by every person who opens a PR.

WHAT YOU’LL DO

• Build and maintain CI pipelines in GitHub Actions: incremental test selection based on affected targets, nightly full builds, and clear triage tooling when main goes red
• Instrument the build: CI telemetry, dashboards showing build and test times broken down by job type, branch, and author — so we stop flying blind on build health
• Define and enforce the policies that keep main green: merge queue configuration, PR gating, and the on-call process when broken builds block other engineers
• Own and maintain the remote build cache infrastructure, ensuring cache correctness, invalidation on environment changes, and read-only promotion from main only
