This is both an upstream and downstream-focused role; an ideal candidate will have experience working in public upstream open source codebases. They will be responsible for building a test suite and test automation for the core engine & runtime codebase on both Linux and Mac platforms, and they will be responsible for evaluating how the quality of models built with the tooling is impacted by updates to the codebase. An interest / familiarity with large language models and/or GPUs or other hardware accelerators will be great for this role. It will be important for this role to have experience working with Linux on the command-line.
