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 ID.me'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., GitHub Actions), contributing to reusable/shared workflow components that other service teams can adopt. * Use AI tools to accelerate test authoring, test plan generation, and code review. * Collaborate with development teams on testable code structure, coverage gaps, and quality checks throughout the development lifecycle. * Debug and root-cause issues across frontend, backend, APIs, and distributed services, and drive fixes to closure. * Help define and track reliability metrics (e.g., time to detect, time to remediate) for the systems you test. ## Related Videos - [Keeping applications secure by evolving OAuth 2.0 and OpenID Connect](https://www.wearedevelopers.com/videos/100152-keeping-applications-secure-by-evolving-oauth-2-0-and-openid-connect) - [Docker Compose: Rediscovered](https://www.wearedevelopers.com/videos/1978-docker-compose-rediscovered) - [Innovating Developer Tools with AI: Insights from GitHub Next](https://www.wearedevelopers.com/videos/1268-innovating-developer-tools-with-ai-insights-from-github-next) - [Continuous testing - run automated tests for every change!](https://www.wearedevelopers.com/videos/190-continuous-testing-run-automated-tests-for-every-change) - [Delay the AI Overlords: How OAuth and OpenFGA Can Keep Your AI Agents from Going Rogue](https://www.wearedevelopers.com/videos/1637-delay-the-ai-overlords-how-oauth-and-openfga-can-keep-your-ai-agents-from-going-rogue) - [Bringing AI Model Testing and Prompt Management to Your Codebase with GitHub Models](https://www.wearedevelopers.com/videos/1536-bringing-ai-model-testing-and-prompt-management-to-your-codebase-with-github-models) ## Related Articles - [The 8 Best Code Testing Tools](https://www.wearedevelopers.com/magazine/402-the-8-best-code-testing-tools) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Dev Digest 137 - AI'm not sure about this](https://www.wearedevelopers.com/magazine/485-dev-digest-137-ai-m-not-sure-about-this) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [13 AI Tools for Developers](https://www.wearedevelopers.com/magazine/302-13-ai-tools-for-developers)
