Senior SDET

• 5+ years of UI test automation, including designing or significantly extending a framework.
• Strong TypeScript/JavaScript and Node.js skills, with substantial hands-on Playwright experience. Strong Cypress or Selenium experience plus willingness to move to Playwright is also fine.
• Working Python skills (pytest, Playwright for Python): test tooling, data setup, backend checks inside UI scenarios, and contributing to the shared framework.
• Experience testing React apps with complex data grids (AG Grid or similar), dynamic forms and heavy client-side state.
• Experience mocking network traffic in the browser (REST and WebSocket) and testing authentication flows.
• Front-end performance testing experience:

Profiling: Chrome DevTools Performance and Memory panels, and the Lighthouse and performance APIs.

Diagnosis: finding long tasks, layout thrashing and memory leaks.

Budgets: setting performance budgets and enforcing them in CI.

• CI/CD experience with Azure DevOps (preferred) or Jenkins/GitHub Actions, and Git.
• Experience building isolated test environments:

Linux: comfortable on the command line, with shell scripting, processes, networking and log troubleshooting.

Docker: Docker and Docker Compose.

AWS: EC2, ECS or EKS, S3, IAM, VPC and CloudWatch.

Infrastructure as code: Terraform, CloudFormation or CDK.

• Strong reliability habits: isolated tests, deterministic waits instead of sleeps, controlled retries, and triage of flaky tests.
• Experience with test reporting and traceability (Playwright reports, Allure, Azure Test Plans, TestRail).
• Clear communication and good documentation.
