About the role

As a SDET, you will play a critical role in shaping and executing our automation-first quality strategy across web, API and AI-driven systems.

You’ll work closely with Engineering and Product teams to ensure that quality is designed into every feature, enforced through strong automation, and protected by strict release gates. This is a hands-on, technically deep role with real ownership and impact.

What you’ll do

Design, build, and maintain scalable automation frameworks using Playwright and SerenityJS
Contribute to the enhancement and scalability of existing automation frameworks
Build and maintain REST API automation using Postman or equivalent tools
Integrate and maintain automated test execution within CI/CD pipelines (e.g., Jenkins, GitHub Actions)
Investigate test failures, perform root cause analysis, and collaborate with engineering teams to resolve issues
Ensure automated test coverage aligns with defined acceptance criteria and release requirements
Participate in automation code reviews to maintain consistency, readability, and maintainability
Support execution of regression, integration, and end-to-end test suites across environments
Collaborate during story refinement and design discussions to identify test scenarios, risks, and edge cases
Contribute to automation reporting, metrics, and continuous quality improvements
Work closely with cross-functional teams to promote quality best practices

Who you are

2+ years of experience in QA Automation / SDET roles
Strong hands-on experience with modern automation frameworks (Playwright preferred)
Proficiency in JavaScript/TypeScript for building maintainable test automation
Solid understanding of REST API testing concepts and tools such as Postman
Experience integrating and running automated tests within CI/CD pipelines
Familiarity with BDD practices and frameworks such as Cucumber
Working knowledge of Git and modern version control workflows
Experience working in containerized environments (e.g., Docker); exposure to Kubernetes is a plus
Understanding of regression, integration, system, and end-to-end testing principles
Ability to debug automation failures and analyze application issues effectively
Strong communication skills and ability to collaborate with developers and product teams

Even better if you have

Exposure to accessibility testing and understanding of WCAG principles
Experience with visual regression or cross-browser testing
Familiarity with cloud-native or SaaS-based platforms
Exposure to AI-assisted testing tools or testing AI-driven features
Experience contributing to automation dashboards or quality metrics

You will thrive in this role if

Believe quality is a shared responsibility across Engineering, QA, and Product
Prefer preventing defects through strong automation and release gates
Enjoy building systems that scale, rather than relying on manual effort
Comfortable enforcing 100% pass-rate mandates for critical workflows
Like working on complex systems involving CI/CD, containers, and AI-driven logic
Care deeply about reliability, trust, accessibility, and real-world user experience
