Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Platform Engineer - Build and CI - **Company:** Humanoid - **Location:** London, UK - **Contract:** Permanent contract - **Skills:** Cloud Computing, CMake, Continuous Integration, Software Debugging, Firmware, Github, Caching, Build Management, Kubernetes, Build Tools - **Published:** June 14, 2026 - **Apply:** https://uk.indeed.com/viewjob?jk=92b13528b2574315 ## About the Role Do you have experience in Kubernetes?, * Solid experience with build systems - ideally Bazel, but deep knowledge of CMake or similar is fine; the instincts matter more than the specific tool * Experience designing and operating CI pipelines at scale: incremental testing, artifact caching, runner management, and keeping feedback loops short * Strong understanding of hermetic build environments * Comfort debugging complex build failures across multiple languages and toolchains * Experience with dependency management and the tradeoffs between reproducibility, speed, and upstream risk * Good instincts for developer experience Nice To Have * Familiarity with ROS/ROS2 build tooling (colcon, ament, CMake) * Familiarity with Kubernetes: self-hosted runners, ARC * Experience with GitHub Actions at scale * Background in robotics or embedded systems where build artifacts span multiple target architectures and deployment environments ## Description 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., 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 * Own the developer environment story - local builds, dependency management, and the tooling that lets engineers iterate quickly without fighting their environment * Maintain and evolve the dependency mirroring infrastructure (apt, PyPI, and other upstream registries) so that external package availability never blocks a build ## Related Videos - [Innovating Developer Tools with AI: Insights from GitHub Next](https://www.wearedevelopers.com/videos/1268-innovating-developer-tools-with-ai-insights-from-github-next) - [Code to Road in < 12 hours](https://www.wearedevelopers.com/videos/1082-code-to-road-in-12-hours) - [HTTP headers that make your website go faster](https://www.wearedevelopers.com/videos/1676-http-headers-that-make-your-website-go-faster) - [Robots are coming into the wild!
