Job Technologies
Your role in the team
- Own and evolve our Bazel-based build system powering our ML compiler platform, ensuring fast, reproducible, and reliable builds across a growing codebase and multiple hardware targets.
- Design and maintain Python packaging and distribution pipelines, delivering our compiler toolchain and runtime components as well-structured, versioned Python wheels for customers and internal teams.
- Champion developer experience by building intuitive tooling, documentation, and self-service workflows that streamline onboarding, reduce friction in local development, and empower engineers to iterate quickly and confidently.
- Develop and optimize CI/CD infrastructure to support rapid iteration, catch regressions early, and scale with the demands of a fast-moving compiler project.
- Manage third-party dependencies, SDKs, and toolchains, ensuring consistent and hermetic build environments across development, testing, and production.
- Collaborate closely with compiler, runtime, and test engineers to integrate new components smoothly, resolve build and linking issues, and keep developer workflows frictionless.
- Improve build performance through caching strategies, parallelization, dependency analysis, and tooling that minimizes developer wait times.
- Define and enforce packaging standards, release processes, and versioning policies that support reliable deployment across diverse edge hardware platforms.
