You will also provide feedback in code reviews, focusing on the robustness and reliability of code changes.

The ideal candidate will have 5+ years of experience in software development and/or performance engineering, fluency in Python, Javascript, or Typescript, and experience working with relational or NoSQL databases.

By six months, you have established yourself as a key owner of automated test frameworks, and demonstrated improvements in test efficiency and coverage.

After twelve months, you are instrumental in ensuring quality of major new features, setting an example for new team members in best practices for correctness and performance test automation and internal tooling.
