About the Role
We are looking for a Senior Software Development Engineer in Test (SDET) to lead automation initiatives across modern web applications and distributed systems. This is a hands-on engineering role where you will design scalable automation frameworks, develop production-grade automation code, and integrate quality engineering practices into CI/CD pipelines. You will collaborate closely with developers, product managers, architects, and DevOps teams to deliver high-quality software through robust automation and continuous testing.
The ideal candidate has extensive experience with Playwright-based UI automation, API test automation, and automation framework architecture, along with a passion for building reliable, maintainable, and scalable test solutions.
Key Responsibilities
UI Automation
- Design, develop, and maintain scalable end-to-end automation frameworks using Playwright and TypeScript.
- Build maintainable automation using Page Object Model (POM) and component-based design patterns.
- Optimize browser context management, parallel execution, and test concurrency for efficient CI execution.
- Develop stable automation by implementing resilient selectors and intelligent synchronization strategies.
- Implement visual regression testing where applicable.
API Automation
- Design and maintain API automation frameworks for REST, GraphQL, and SOAP services using Python and pytest.
- Develop reusable fixtures, API clients, and parameterized test suites.
- Build GraphQL schema validation and operation-level assertion libraries.
- Create API performance and SLA validation checks.
- Maintain Postman and Newman collections for API smoke and contract testing.
CI/CD & Automation
- Integrate automated tests into Jenkins and GitHub Actions pipelines.
- Design automated quality gates supporting smoke, sanity, functional, and regression testing.
- Build fail-fast deployment validation and post-deployment verification pipelines.
- Monitor automation execution, maintain reporting dashboards, and improve pipeline reliability.
- Identify and eliminate flaky tests through continuous framework improvements.
Mocking & Service Virtualization
- Design and maintain WireMock stubs for dependent service simulation.
- Support consumer-driven contract testing.
- Maintain mock services aligned with evolving API contracts.
- Enable local development through mock-first testing strategies.
Automation Architecture
- Establish automation coding standards, framework architecture, and best practices.
- Develop reusable utilities, fixtures, data builders, and shared automation libraries.
- Review automation code and mentor engineers on automation design principles.
- Evaluate emerging automation technologies and recommend improvements where appropriate.
Collaboration & Leadership
- Mentor junior and mid-level automation engineers through code reviews and technical guidance.
- Partner with development teams to improve application testability during design.
- Work closely with DevOps teams to optimize automation infrastructure and execution environments.
- Maintain traceability between requirements, user stories, and automated tests using Jira.
- Present automation metrics, test coverage, and quality reports to engineering stakeholders.
