**Company:** [Datadog](https://hotfix.jobs/companies/datadog)
**Location:** Atlanta, GA, Boston, MA, New York, NY
**Role:** DevOps / SRE
**Salary:** $244k – $305k/yr
**Experience:** 5+ years
**Skills:** Bazel, Go, Python, Java, Rust, TypeScript, CI/CD, monorepo
**Posted:** 2026-07-29

> Senior engineer building and improving Bazel-based build, test, and packaging tools for Datadog's large multi-language monorepo. Own projects end-to-end to boost developer productivity, performance, and CI efficiency at massive scale.

## Job Description

## 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.
