•Translate requirements into clear, testable acceptance criteria
•Work with engineers and stakeholders to remove ambiguity and make expected behavior objectively verifiable
•Validate end-to-end customer journeys across cart, checkout, ordering, billing, invoicing, authentication, and related integrations
•Verify changes and provide evidence through meaningful test results, coverage, and validation of expected behavior and failure scenarios in pull requests
•Use AI-assisted engineering tools daily for testing, automation, and review; critically validate generated output and remain accountable for the final result
•Review other engineers' code and test changes, identify quality, reliability, integration, and design risks early, and provide actionable feedback
•Improve testing efficiency and reduce manual effort by automating repetitive validation where practical
•Support production quality by participating in incident analysis, identifying test coverage gaps, and improving automated testing and engineering practices based on production issues
•Work across existing and unfamiliar systems, understand complex or legacy applications and integrations, and develop effective test coverage without unnecessary rewrites
•Mentor engineers in quality practices and share testing approaches, automation techniques, and quality standards across the team
•Coordinate quality dependencies across teams, identify integration risks early, and work with relevant engineers to ensure cross-team changes are tested appropriately
•Participate in the on-call rotation for the systems you build

•Experience defining test strategies and translating requirements into clear, testable acceptance criteria
•Experience working closely with software engineers throughout the development lifecycle, not only after development is complete
•Ability to read and understand application code to identify risks, test gaps, and potential defects
•Experience with production systems and incident analysis, including using production issues to improve test coverage
•Hands-on experience with AI-assisted engineering or testing tools in day-to-day technical work
•Strong written communication skills and ability to work effectively in a remote, distributed team across multiple time zones
Nice to have
