Tweag is a software consultancy that helps engineering organizations overcome technical bottlenecks that stand in the way of success. Our work in scalable build systems, primarily through Bazel, helps our clients grow their tech organization without the maintenance burden.

Tweag works with organizations at all experience levels, from trying out Bazel for the first time, to refactoring and scaling Bazel workspaces with hundreds of thousands of potential targets. In every situation, we are the experts, helping them achieve their goals and delighting them with improvements they never expected.

We are looking for someone who can handle:

• Integration with as-yet-unsupported languages.
• Development of specialized Bazel toolchains.
• Improving open-source Bazel rules to unblock our clients.
• Using Gazelle to standardize and clean up code.
• Refactoring Bazel code, and teaching others how to do so.
• Debugging the internals of Bazel.

• Ties to the Bazel community.
• Active maintenance of Bazel open-source tools.
• Expertise in Bazel performance optimization, both within rules and in evaluating the build graph.
• Knowledge of other reproducible build systems, such as Nix, Buck2, or Pants.

• A fully remote workplace with strong respect for work-life balance.
• Working on complex engineering problems, often with no right answer.
• A research-informed culture, with plenty of nerding out about computer science and mathematics.
• Giving back to the community by contributing to open-source software, contributing to our blog, participating in working groups, and stewarding conferences.
