Build Engineer

Zeromatter Technologies Inc; Mountain View (CA); On-site; USD 120,000 - 170,000; Full time

Job summary

Zeromatter Technologies Inc is seeking a Build Engineer to architect and deploy scalable build infrastructure for a multi-language codebase (Rust, C++, Python, TypeScript). You will lead the migration from Cargo to Bazel, design robust build solutions, and optimize performance across CI/CD pipelines.

You will influence development velocity, improve caching, parallel builds, and reproducible builds while partnering with engineering across robotics and automotive domains.

Qualifications

• Engineering degree or equivalent working experience.
• Deep experience with cross-platform, hermetic C++ toolchains and custom rules in Starlark-based build systems.
• Strong programming skills in Rust, C++, and Python, especially focused on how code is packaged, compiled and executed.
• Proven track record of build system migrations in production environments.
• Experience with build optimization techniques including distributed builds and caching.
• Familiarity with CI/CD systems and infrastructure automation.
• Strong debugging and performance analysis skills.
• Experience with hermetic and reproducible builds.
• Bonus: Knowledge of GPU build toolchains and CUDA compilation.
• Bonus: Familiarity with packaging and distribution systems (.deb, .rpm, python wheels, npm packages, rust crates, etc).

Responsibilities

• Lead migration from Cargo to Bazel (or similar) while ensuring minimal disruption to development velocity.
• Design and implement build solutions for our multi-language stack (Rust, C++, Python, and TypeScript).
• Optimize build performance through caching strategies, distributed builds, and incremental compilation.
• Create and maintain build tooling that enables rapid local development and testing workflows.
• Establish build system best practices and documentation to empower the entire engineering team.
• Integrate build systems with our CI/CD pipelines for seamless automated testing and deployment.
• Monitor and improve build times, identifying bottlenecks and implementing solutions.
• Collaborate with all stakeholders to ensure our build infrastructure scales with our growing company and codebase.
