What You Bring

• You get up to speed quickly on unfamiliar systems and complex codebases, understanding how components connect and becoming productive on active production suites without needing hand-holding.
• You have hands-on experience designing, writing, and maintaining automated tests, with a strong understanding of test case design, defect tracking, and regression prevention.
• You write clean, functional Python for test automation and scripting, and you are comfortable building utilities, data-setup scripts, or running API tests with tools like pytest or Postman.
• You understand that machine learning models and AI agents fail differently from traditional deterministic code, and you are eager to test data contracts, pipeline reproducibility, and edge cases where output legitimately changes between runs.
• When it comes to AI, you already rely on coding assistants and LLMs to generate test scaffolding, write scripts, or inspect errors, with the sharp judgment to catch hallucinations, verify assertions, and reject code that falls short.
