• Quality strategy for our clinical platform • Define what quality means at Heartbeat, how we measure it, and how we improve it - across partner-specific configurations, clinical decision support, workflow orchestration, and integration points. You own the quality outcomes, not just the test artifacts. • Validation architecture • Design the systems that make validation fast, reliable, and low-friction - test data strategies, environment management, automation frameworks, CI/CD integration. Give engineers back time by making quality infrastructure a force multiplier, not a tax. • Release confidence • Strengthen release predictability by systematizing validation earlier in the development lifecycle. When something ships, the team should know - with evidence - that it works. • Embedded cross-functional partnership • This is not a handoff role. You'll sit inside the development process - participating in refinement, influencing how work is scoped and acceptance criteria are defined, shaping what "done" means. You're a core member of a small, high-impact team where everyone has direct access to product, engineering, and clinical leadership. • Exploratory testing where it matters • Perform targeted exploratory testing on high-risk areas - new features, edge cases, partner-specific configuration behavior, clinical workflow paths. You know when automation is the right tool and when human judgment is the only tool.
