As a Software Development Engineer III on the Quality Engineering team, you will build and maintain automation frameworks and testing infrastructure that give  engineering teams the confidence to ship quickly and safely. You’ll build tooling for functional, end-to-end, and security-focused test automation, help extend testing coverage into production through canary releases and progressive delivery, and apply AI-assisted testing practices as part of the team’s broader adoption.

This includes building test coverage for consumer-facing commerce and marketplace experiences (offers, cashback, affiliate/attribution flows) alongside core platform and identity services. You’ll work closely with engineering, product, and security teams to raise the bar on quality and resilience across a platform that verifies the identity of millions of users and the commerce experiences built on top of it.

• Build and maintain automation frameworks (Playwright, Python, Jest, API automation) that provide comprehensive, reliable test coverage across ’s services.
• Develop end-to-end and integration tests for complex, asynchronous, event-driven, and eventually-consistent systems, including workflow orchestration platforms such as Temporal.
• Support testing-in-production practices, including canary deployments, progressive/phased rollouts, synthetic monitoring, and automated rollback triggers, to help validate real-world behavior safely before full release.
• Build and maintain test automation for commerce and marketplace surfaces, such as offers, cashback, affiliate/attribution and click-tracking accuracy, consent gates, and persona-based experiences (e.g., logged-in/out, member-group-specific offers), including client-side surfaces like browser extensions.
• Integrate automated testing into CI/CD pipelines (e.g., Git Hub Actions), contributing to reusable/shared workflow components that other service teams can…
