.The Language Tools team enables hundreds of Datadog backend engineers to build, test, and package secure, quality code. Our success is measured by their productivity and happiness.They use the tools that we develop and support several times a day; in dev and CI; in diverse Git repositories, from very large polyglot or monoglot repositories (monorepos, sic) to smaller repositories scoped to services or libraries ("micro-repos"); and in various languages, including Go, Python, Java, Rust, and TypeScript. To orchestrate our builds, we use either Bazel or industry standard tools for the language, depending on the repository.The team is growing rapidly, not only following Datadog's growth, but also taking over repositories and languages that were formerly managed by their users. As a senior software engineer on the team, you will own projects from start to finish, both greenfield and brownfield. You will gain first-hand understanding of what Datadog developers need, and inform our roadmap.At Datadog, we place value in our office culture - the relationships that it builds, the creativity it brings to the table, and the collaboration of being together. We operate as a hybrid workplace to ensure our employees can create a work-life harmony that best fits them.What You'll Do:Invent simpler, faster, more reliable, and more efficient build, test, and packaging tools.Treat CI like SREs treat prod, making sure our pipelines are green and fast.Prepare, run, and finish complex migrations.Promote coding best practices company-wide: linting, formatting, type checking, etc.Engage with the open source community as needed. For example, influence and/or contribute to the Bazel roadmap, or report issues with Go release candidates.Who You Are:An expert in one or more of the languages or build systems listed above.A well-rounded engineer. You must broadly understand the various types of software projects that are built, tested, and packaged with our tools.Both careful and fearless. The changes we make impact the velocity of hundreds of engineers. They are risky but necessary.User-focused. We help Datadog engineers to use the tools that we develop, and continuously improve their usability, so they don't need our help the next time.Ideally, you have experience working with a large codebase.Datadog values people from all walks of life. We understand not everyone will meet all the above qualifications on day one. That's okay. If you're passionate about technology and want to grow your skills, we encourage you to apply
