Staff Bazel Build & CI Automation Lead

D-Matrix Corp.; Santa Clara (CA); Hybrid; USD 180,000 - 240,000; Full time

Job summary

d-Matrix is advancing a Bazel-based build-out to power a fast, reliable AI-focused platform. You will finish the in-progress Bazel migration, design the distributed build infrastructure, and own the build graph, toolchains, caching and remote execution.

You will partner with development teams and with the engineers who run our runner fleet and cloud environments. When build and test time drops, every team moves faster.

Qualifications

• Deep Bazel experience as an owner: custom rules, toolchains, and target graph design in a large repository.
• Experience migrating a real codebase onto Bazel, including the long tail.
• Hands-on experience deploying and operating remote caching or remote execution.

Responsibilities

• Complete the Bazel migration, including the hardest remaining components.
• Migrate the test suite to Bazel, with correct tagging and sharding, and route hardware-dependent tests to executors that have the hardware.
• Design, deploy, and operate remote execution in production.
• Build hermetic toolchains and reproducible builds across developer machines, CI, and hardware-attached runners.
• Raise cache hit rate to target and build trust in the cache, so no one runs a clean build "to be safe."
• Establish a build-time baseline in your first quarter, then reduce median incremental build time and CI critical path against it.
• Evolve the CI/CD system to keep pace with agent-assisted development.
• Raise the standard of Bazel usage across teams by making the correct path the easy one and sharing best practices.
