• Self-hosted GitHub Actions runners for image build pipelines

• Docker for reproducible build environments

• Power management and thermal constraints on airborne platforms

• Experience with restricted or air-gapped development environments

YOUR TASKS MAY INCLUDE

• Designing and maintaining the Raspberry Pi OS images our navigation software runs on — minimal, reproducible, versioned

• Building and operating the secure boot and provisioning chain: signing keys, OTP key programming, encrypted rootfs, factory provisioning stations

• Automating image build, signing and flashing in CI, so a release is an artifact rather than a manual procedure

• Bringing up new hardware revisions and peripherals together with the hardware team

• Implementing and testing a safe field update mechanism, including rollback

• Debugging boot, driver and performance issues on real devices — serial console, ftrace, perf, kernel logs

• Hardening the platform: attack surface reduction, secrets storage, protecting IP on a device that can be physically captured
