Staff Platform Engineer - Developer Infrastructure

• The build graph for a mixed C++/Python/Rust/CUDA monorepo: involving incremental correctness, remote caching, and cross-compilation for AMD64 dev boxes and ARM64 targets.

• Our CI capacity: self-hosted runners, GPU and hardware-attached runners, and the queue discipline that keeps PR feedback under ten minutes.

• Reproducibility: A build from a tagged commit six months from now should produce a bit-identical artifact.
  

• Versioning, artifact promotion, and the container registry / package mirrors that back it.

• Safe, resumable, bandwidth-aware rollout to robots - staged channels, canary robots, and rollback that works over a bad link.

• Signing and provenance for anything that lands on a robot.
  

• Reproducible dev environments across laptops, shared dev machines, and robots.

• Self-service tooling so an autonomy engineer can get a branch onto a robot without filing a ticket or learning Kubernetes.

• Onboarding path: a new engineer builds, tests in sim, and deploys to a bench robot on day one.
  

• Cloud and on-prem compute, storage for multi-TB robot logs, and the training/simulation cluster's operational layer.

• Fleet observability: metrics, logs, and traces from robot to dashboard.

• Site infrastructure for deployments: VPN/overlay networking, local mirrors, offline-capable registry authorization.

• 8+ years operating production infrastructure for a software engineering org, with direct ownership of CI/CD or developer platform work.

• Deep Linux systems fluency including networking, storage, systemd, kernel and driver debugging.

• Hands-on ownership of a major CI system (GitHub Actions, GitLab CI, Buildkite, Jenkins) and an understanding of the build and cache layers underneath it.

• Real experience with a C/C++ build system at scale e.g., Bazel, CMake, or equivalent. Should include cross-compilation and dependency pinning.

• Infrastructure as code (Ansible, Terraform) and a GitOps mindset: reviewable, reproducible, version-controlled change.

• Fluent Python and Bash. You automate rather than document a manual procedure.

• Strong written communication. You leave behind decisions that outlast the conversation.

• Shipping software to embedded or edge Linux targets - ARM64, Jetson, Yocto/custom images, A/B partitions, OTA update systems.

• Hybrid on-prem plus cloud, and clear judgment about which belongs where.

• Open-source observability stack (Prometheus, Grafana, OpenTelemetry) and self-hosted services (registries, artifact stores, object storage).

• Robotics, autonomous vehicles, aerospace, or another hardware-heavy environment where a bad release has physical consequences.

• Nix, Bazel remote execution, or other tools for reproducible builds at scale.
