About this role

Nexxa is hiring for a Senior Software Development Engineer in Test (SDET), QA - AI Systems role (full-time). See the official posting for full details.

Requirements

  • 5+ years as an SDET, QA engineer, or software engineer with a strong testing focus, with demonstrated ownership of test strategy and automation for complex distributed systems.
  • Proven experience in both manual and automated testing, including exploratory testing, test planning, and writing high-quality bug reports.
  • Strong programming skills (Python preferred) with a software engineering mindset: clean, maintainable, well-reviewed code for frameworks, data pipelines, and tooling.
  • Experience building test frameworks and infrastructure from the ground up, not just writing test cases within an existing framework.
  • Hands-on experience with CI/CD systems (e.g., GitHub Actions, GitLab CI, Jenkins) and containerized test environments (Docker, Kubernetes).
  • Experience testing APIs and microservices, including contract, integration, and end-to-end testing.
  • Hands-on experience testing LLM-based products, chatbots, or AI agents, and an understanding of why traditional deterministic assertions break down for generative systems.
  • Practical experience with eval frameworks or tooling (e.g., promptfoo, DeepEval, RAGAS, LangSmith) or a track record of building your own.
