Software Engineer

Who you are

• Hands-on experience maintaining Bazel (or a comparable system such as Buck or Pants) in a multi-language monorepo: writing rules and macros, configuring toolchains, and debugging build and cache correctness
• Experience with remote caching and remote execution (for example BuildBuddy, EngFlow, Buildbarn, or NativeLink) is a significant plus
• Strong knowledge of build systems and other tools in the software development cycle, like: git, linting, GitHub, code review, testing frameworks and deployment frameworks
• Working knowledge of C++ build toolchains (compilers, linkers, sysroots, cross-compilation)
• Strong knowledge of CI/CD best practices and principles, with bonus points for direct experience with Buildkite
• Experience developing tools and services in Python or Go
• Experience with Linux operating systems in both day-to-day development and operational environments
• Knowledge of AWS or other similar cloud platforms; Terraform experience is a plus
• Knowledge of on-call support processes, incident management and monitoring tooling
• Familiarity with front-end web development (for example HTML, CSS, JavaScript, or a modern framework) sufficient to build and maintain simple internal tools and dashboards is a plus

What the job involves

• The Developer Platform team as a part of Software Foundations and Architecture is responsible for building and maintaining the infrastructure that enables all developers to track, build, deploy and operate our software
• From the build system everyone uses, to AI and local developer tools, to the tools used to submit and deploy changes, to the cloud infrastructure they use to operate it - we support the entire development experience
• The Developer Platform team forges the tools that empower the entire software engineering organization while working with engineers from almost every team
• Every engineer at Glydways builds, tests, and ships through our Bazel monorepo, so its speed and reliability set the pace for the whole company
• This role owns that foundation: keeping builds fast, hermetic, and correct across C++, Python, and Go, and scaling them with remote caching and remote build execution
• Rolling out remote build execution and improving remote cache hit rates across CI and developer machines
• Profiling and cutting build and test times in the monorepo, and keeping builds hermetic and reproducible
• Upgrading and maintaining Bazel, rulesets, and external dependencies (Bzlmod)
• Supporting C++ toolchains and cross-compilation for our embedded targets
• Building dashboards and alerts for build health, flaky tests, and CI performance
• General developer workflow and CI work alongside the rest of the team
• Own and evolve our Bazel build system, keeping it fast, reliable, hermetic, and easy to use for every engineer
• Design and roll out remote caching and remote build execution (RBE), and tune build and test performance across local and CI environments
• Maintain rules, toolchains, and dependency management for C++, Python, and Go, including cross-compilation for embedded targets
• Maintain and enhance developer workflows, including build, lint, code coverage, and testing support for C++, Python, and Go languages
• Collaborate closely with software engineering teams to identify and implement improvements in the continuous integration (CI) system, utilizing AWS and Buildkite
• Develop, deploy, and support automation tools to streamline common developer workflows, such as change submission, integration testing, and dependency management
• Design and implement basic monitoring services and dashboards to track build health, cache hit rates, and the performance and stability of internal processes and systems
• Participate in the team's support and on-call rotation, responding to issues and keeping shared developer infrastructure healthy
