  • Establish staged rollout, canary, and rollback strategies collaboratively with engineering and SRE/Ops.
  • Set test architecture principles covering unit, end-to-end, performance, playback, stream validation, integration, and contract testing.
  • Partner on major quality incidents and convert production failures into tests, monitors, gate changes, and rollout improvements.
  • Define standards for test frameworks, CI integration, test data, environments, reporting, and AI-assisted testing.
  • Embed risk-based testing, quality practices in pull requests, flake policies, critical-path coverage, and quality standards into engineering teams.

  • Hands-on experience applying AI to quality engineering, including judgment about when it reduces risk or adds noise.
  • Experience partnering on incidents and turning production failure modes into durable quality improvements.
  • Strong influence and communication skills, with the ability to establish standards and enforce quality gates without formal authority.
  • Bonus experience with video ingest, encoding, packaging, playback, or multi-tenant configuration and policy surfaces.
  • Experience working across web, TV, and mobile client quality risks, including device, operating system, and app-store constraints.
