Who you are

• 5+ years of experience in software engineering, SDET, or test automation roles
• Proven experience designing and maintaining test automation frameworks at scale
• Experience with API, integration, and end-to-end testing patterns
• Strong understanding of CI/CD systems and test pipeline optimization
• Experience improving test reliability, performance, and maintainability
• Ability to design systems for testability (e.g., dependency injection, contract testing)
• Experience working with distributed systems and understanding failure modes
• Experience with payments, e-commerce, or financial systems (preferred)
• Strong collaboration skills and ability to influence engineering practices

What the job involves

• We’re hiring a Senior SDET to own the engineering of quality for revenue-critical payment systems. This role focuses on building and evolving automated testing systems, improving developer workflows, and ensuring quality is enforced through engineering practices and not just manual validation
• Own the design, development, and maintenance of scalable automated test frameworks (Playwright, API, integration, end-to-end)
• Build and operate reliable test infrastructure integrated into CI/CD pipelines
• Drive test automation strategy, optimizing for coverage, speed, and signal quality
• Identify systemic quality gaps and address them through tooling and engineering improvements
• Partner with engineers to design systems for testability (e.g., observability, contracts, idempotency)
• Write production-quality code for test systems, utilities, and supporting infrastructure
• Improve developer experience by enabling fast, reliable feedback loops
• Validate complex payment flows and external integrations (e.g., Stripe) through automation-first approaches
• Lead root cause analysis for defects and implement systemic fixes to prevent recurrence
• Define and enforce quality standards for high-reliability, revenue-critical systems
