• Collaborate with clinical profiles to validate AI agent behavior.

• Develop quality gates, metrics, scorecards, and defect analyses.

Must have

• 8–10+ years of QA experience in complex distributed systems.

• Strong automation experience (Python, Playwright, PyTest, or others).

• Experience testing healthcare, regulated, or mission-critical systems.

• Strong understanding of clinical workflows, or genuine willingness to learn them deeply.

• Excellent communicator with very high attention to detail.

Nice to have

• Experience evaluating ML or AI agent outputs.

• Experience in safety-critical industries (healthcare, aviation, fintech, etc.).

Why Join

• Work on cutting-edge AI technology with tangible clinical impact.

• Collaborate with visionary founders who built billion-dollar companies.

• Shape the foundation of a high-growth product and engineering team in Barcelona.

• Build AI products that balance speed, safety, and science—a rare opportunity in HealthTech.
