Requirements

What you’ll need

Significant hands-on experience as an SDET, Test Automation Engineer, or Quality Engineer in a software product environment
Deep expertise building test automation frameworks from scratch (not just writing scripts in existing frameworks)—you've made architectural decisions about tooling, patterns, and infrastructure
Strong programming skills in Java, Python, TypeScript, or similar languages; you write production-quality code
Experience testing modern web applications built on frameworks like React/Next.js/React Native/Flutter and backend services on Spring Boot or similar JVM-based stacks
Proficiency with API and integration testing tools and practices (REST, GraphQL, contract testing)
Hands-on experience integrating automated tests into CI/CD pipelines (GitHub Actions, Jenkins, or similar)
Experience with cloud infrastructure (AWS preferred): understanding of how to test applications running on Lambda, Step Functions, API Gateway, DynamoDB, and related services
Strong debugging and root cause analysis skills—you can read application code, trace through distributed systems, and pinpoint where things break
Excellent communication skills and the ability to influence engineering teams on quality practices as a peer, not a gatekeeper
Bachelor's degree in Computer Science or equivalent practical experience.
