  • Mentor and scale a distributed QA team; run quality guilds, workshops, and AI upskilling sessions.

Testing and AI innovation

  • Conduct exploratory, usability, and compliance testing across devices, operating systems, browsers, and wearable hardware SKUs.
  • Pilot generative AI platforms for test-case authoring, data fabrication, and defect triage; evaluate solutions, build proofs of concept, and drive adoption.
  • Use ML-based anomaly detection in observability pipelines to trigger self-healing tests.

Infrastructure and collaboration

  • Partner with DevOps to enhance CI/CD pipelines for parallelized, containerized test execution and implement security and privacy test automation.
  • Work with Product, Engineering, Design, Customer Support, and Release teams on quality goals, release readiness, and feedback loops.
  • Provide data-driven insights to shape roadmap priorities and AI feature rollouts.

Required experience and qualifications

  • 9+ years of progressive QA experience, including 2+ years leading a QA team.
  • Experience testing OS-level and/or hardware, mobile, cloud, and AI/ML solutions in consumer or IoT environments.
  • API testing experience with REST, gRPC, or GraphQL, plus message queues, microservices, and data pipelines.
  • Demonstrated AI-tool use in QA or development workflows and strong knowledge of Agile, Waterfall, and DevSecOps.
  • Bachelor’s degree in Electronics or Electrical Engineering, or equivalent proven experience.
  • Must be eligible to work in Canada and fluent in English.

Preferred certification
