The Language Tools team enables ~1,500 Datadog developers to build, test, and package millions of lines of Go, Python, Java, Rust, and TypeScript in our backend monorepo. Our success is measured by their productivity and satisfaction. They use the tools that we develop and support several times a day, in both development and CI environments. We use the Bazel open source build system as a foundation.
The team is growing rapidly, both with Datadog and as we absorb other repositories into the monorepo. 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 build, test and packaging tools that are simpler and more reliable to use.
- Push performance and cost efficiency at scale, raising cache hit rates and cutting CI times and compute spend across millions of targets.
- Treat CI like SREs treat prod, making sure our pipelines are green and fast.
- Prepare, run, and finish complex migrations.
- Contribute back to the Bazel ecosystem, upstreaming fixes and shaping features we depend on.
Who You Are:
- An expert in Bazel and/or one of the languages 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.
