  • Design and deliver the testing platform, including test frameworks, test data services, and observability tools.
  • Provide SDKs and templates for consistent test authoring.
  • Partner with teams to bootstrap test coverage and establish shift-left practices.

  • Lead offshore engineers and collaborate with cross-functional teams.
  • 10+ years in software quality engineering/test automation, with 3–5 years in testing platforms or developer enablement.
  • Experience in data platforms and data product testing.
  • Strong automation skills in Python or Java with CI/CD integration.
  • Proven experience establishing federated quality practices.
