• You will integrate automation with real hardware, simulators, and emulators.
• You will integrate automated tests into CI/CD pipelines supporting firmware, mobile, and system-level builds.
• You will develop tooling to enable repeatable, deterministic testing of distributed medical devices.
• You will maintain test environments, mocks, and simulators as systems evolve.
• You will ensure automation supports regulatory-compliant verification evidence.
• You will produce automation logs, artifacts, and reports suitable for design history files (DHF).
• You will work closely with verification engineers, firmware developers, systems engineers, and quality teams.
• You will support root-cause investigations using automated diagnostics and captured data.

What makes you successful:

• You have experience working with medical devices, wearables, or safety-critical systems.
