Sr. QA Engineer at RenesasElectronics

  About the role: The Senior QA Engineer on the Duro Design team defines, builds, and scales the quality systems that ensure hardware engineers can rely on our platform every day. You’ll architect and implement quality strategy across our modern stack—from frontend interfaces to backend services—embedding confidence into how we design, ship, and operate software. This role partners closely with engineering, product, and DevOps teammates in a fast-moving, highly autonomous environment. We’re looking for engineers who think systemically about risk, embrace experimentation, and leverage modern AI-powered workflows to elevate quality across the organization. This is a hybrid role based in Los Angeles, CA (3 days per week in office). A day in the life of our Senior QA Engineer: Quality Strategy Ownership: Define and evolve our end-to-end quality strategy, determining what gets tested, at which layer, and how coverage maps to real user risk. Test Architecture: Design and maintain scalable test infrastructure across unit, integration, and end-to-end layers using modern frameworks such as Vitest, Jest, and Playwright. Cross-Functional Collaboration: Partner early with product and engineering teams to ensure features are testable by design and quality is embedded before code reaches production. Full Stack Validation: Validate React interfaces, GraphQL APIs, and PostgreSQL data integrity to ensure system-wide reliability. CI/CD Optimization: Architect and refine test pipelines in GitHub Actions (or similar) to balance speed, coverage, and deployment confidence. Experimentation & Analytics: Leverage PostHog session replays, feature flags, and analytics to detect regressions, surface edge cases, and proactively identify risk. AI-Driven Quality Engineering: Utilize AI-augmented development workflows to generate test scaffolding, explore edge cases, and increase velocity while maintaining rigorous standards. Continuous Improvement: Lead regression analysis and incident retrospectives, transforming defects into systemic improvements that strengthen long-term product resilience.
