About the Role

We are looking for a Technical Senior Quality Engineer with 5+ years of experience to lead and deliver quality engineering across Java backend and React frontend applications. You will bring strong test automation skills across the full stack — unit, integration, API, UI, and E2E testing — embedding quality as a first-class concern across Agile delivery teams. This is a hands-on technical QE role requiring strong coding ability in Java and JavaScript, deep automation framework expertise, and a shift-left quality mindset.

Key Responsibilities

Test Automation & Framework Development

• Design, build, and maintain scalable test automation frameworks for Java backend and React frontend applications — covering UI, API, integration, and E2E testing layers.
• Develop Java-based automation scripts using Selenium WebDriver or Playwright — supporting functional, regression, and cross-browser testing across enterprise web applications.
• Build React / JavaScript frontend test suites using Jest, React Testing Library, and Playwright — ensuring component-level and E2E UI quality across frontend releases.
• Develop API test automation suites using RestAssured, Karate, or Postman — covering REST API contracts, authentication flows, and business logic validation across Java backend services.
• Write unit and integration tests using JUnit and Mockito — collaborating with Java developers to improve code testability and unit test coverage across backend microservices.
• Build and maintain BDD test frameworks using Cucumber and Gherkin — working with product owners and BAs to define business-readable acceptance criteria and test scenarios.
• Design and execute performance and load tests using JMeter or Gatling — validating Java backend scalability and response time under realistic load conditions.

Shift-Left & CI/CD Quality Integration

• Embed automated test suites into CI/CD pipelines — Jenkins, GitLab CI, or GitHub Actions — implementing quality gates that prevent defective code from reaching production.
• Champion shift-left testing practices — engaging with Java developers, React engineers, and architects early in the delivery lifecycle to define testability requirements.
• Implement contract testing using Pact or Spring Cloud Contract — validating microservices API contracts and preventing integration failures across service boundaries.
• Configure test reporting and observability — Allure, ExtentReports, or ReportPortal — providing clear, actionable quality metrics for engineering and stakeholder audiences.
• Support shift-right testing — production monitoring, synthetic testing, and canary release validation strategies.

Quality Leadership & Collaboration

• Define and own quality engineering strategy across assigned squads — establishing test approaches, automation roadmaps, and quality metrics.
• Lead test planning, estimation, and risk-based prioritisation — ensuring test coverage is proportionate to business and technical risk.
• Conduct thorough code reviews of test automation code — ensuring framework quality, maintainability, and adherence to coding standards.
• Collaborate with Java developers, React engineers, product owners, BAs, and DevOps teams — contributing to Agile sprint delivery from requirements through to production.
• Manage defect triage, root cause analysis, and quality reporting — providing clear quality status updates to delivery teams and stakeholders.
• Mentor and coach junior QE team members — sharing automation expertise across Java and React testing domains.

What We're Looking For

• 5+ years of quality engineering experience with strong hands-on technical automation expertise across Java backend and React frontend applications.

• Strong Java skills — writing production-quality test automation code, unit tests (JUnit / Mockito), and API tests (RestAssured) in Java.

• Proven Selenium WebDriver or Playwright expertise — building scalable, maintainable UI automation frameworks from scratch.

• Solid React / JavaScript testing skills — Jest, React Testing Library, and Playwright for component-level and E2E frontend testing.

• Strong API testing expertise — REST API validation using RestAssured, Karate, or Postman across Java microservices.

• Experience with BDD frameworks — Cucumber / Gherkin — for business-readable test scenario development.

• Hands-on CI/CD integration experience — embedding quality gates and automated test suites into Jenkins, GitLab CI, or GitHub Actions pipelines.

• Strong understanding of shift-left testing practices — engaging early in the delivery lifecycle to define testability and quality requirements.

• Good understanding of microservices architecture — sufficient to design effective integration and contract testing strategies across distributed Java services.

• Excellent communication and collaboration skills — working effectively across Java developers, React engineers, product owners, and DevOps teams.

Nice to Have

• Performance and load testing experience — JMeter, Gatling, or k6 — for Java backend scalability validation.
• Contract testing experience — Pact or Spring Cloud Contract — for microservices API contract validation.
• Accessibility testing knowledge — WCAG standards and tools such as Axe.
• AI-assisted testing tools — Mabl, Testim, or Applitools — for self-healing and intelligent test automation.
• Security testing awareness — OWASP Top 10 and basic DAST / SAST concepts.
• ISTQB Foundation or Advanced certification.
• Experience in Financial Services, Banking, or regulated industry environments.
