QA Engineer (Automation + Functional

• United States - Remote (within location)

Rhythm Science, Inc.
· Remote (US, West Coast hours preferred)
· Full-Time

Rhythm Science builds clinical-grade remote monitoring software for cardiac care. Our platform is used by cardiology practices and health systems across the US to monitor thousands of patients. We're a growing Series A company building the infrastructure layer for cardiac care delivery.

We're looking for an engineer who owns software quality hands-on, from building automated test coverage to partnering with product on test plans before a line of code is written.

• - Build and maintain automated end-to-end and regression tests (Playwright) and keep them running reliably in CI/CD
• - Run functional, regression, and integration testing across our web and mobile apps
• - Partner directly with product and engineering to develop test plans for new features. You'll be involved early, helping define acceptance criteria, not handed a finished spec to validate
• - Help define release readiness criteria and quality gates as the team grows
• - Triage, reproduce, and clearly document defects; track quality signals (escaped defects, coverage, flake rate) and surface them to the team
• - Improve our testing tooling and processes as we scale

• - 3+ years in software QA with hands-on automation experience (Playwright or equivalent)
• - Comfortable writing test plans from product requirements and owning them through release
• - Experience integrating automated tests into CI/CD pipelines
• - Pragmatic and self-directed in a fast-moving startup. You build the process, not just follow it
• - US-based with solid West Coast (PT) overlap for day-to-day work with product and engineering
• - Strong written communication for clear, reproducible bug reports and test documentation

• - Experience testing HIPAA-compliant systems or an understanding of PHI data-handling requirements
• - API testing experience, or familiarity with EHR integrations (HL7/FHIR)
• - Background in healthcare SaaS, RPM, or clinical data platforms

• - Base salary $95, DOE
• - Meaningful equity at a growth-stage company
• - Full benefits, remote-first culture
