We are the team of Software Development Engineers in Test (SDET) - the voice of quality within Engineering squads and the guardians of Continuous Delivery and Innovation.

- Proficiency in JavaScript/TypeScript preferred, proficiency in any functional or general-purpose language considered
- Hands-on experience with AI-assisted testing – using AI tools to generate tests, triage failures, maintain self-healing locators, or analyze coverage gaps – and a mindset of folding these into everyday workflows
- API testing knowledge – REST/GraphQL, request/response validation, auth flows, and API-level automation
