The Ideal Candidate

As part of our transformation journey toward quality automation, we are strengthening our Quality Engineering capabilities. We are looking for a pragmatic Quality Engineer who can take ownership of manual integration testing across multiple teams while also designing and evolving automated test coverage.

This role suits someone comfortable working hands-on across systems today, while actively driving automation maturity over time.

The Role

The Senior Quality Engineer: Automation & Integration Testing is responsible for ensuring high product quality across multiple teams, with a strong initial focus on manual integration testing between three development teams, alongside building and maintaining automated tests.

The role plays a critical part in validating cross-service workflows, identifying integration risks early, and progressively strengthening automation to support continuous integration and delivery. The engineer collaborates closely with development and product teams to embed quality throughout the software development lifecycle.

Responsibilities

• Own and execute manual integration testing across three development teams, validating cross service workflows, data flows, and end to end customer journeys.
• Design and execute risk-based test strategies, using manual and exploratory testing where automation is not yet feasible or effective.
• Define, build, and maintain automated integration and end to end tests, with a clear focus on gradually reducing manual effort through sustainable automation.
• Collaborate closely with developers to validate integration points, APIs, contracts, and system behaviour across environments.
• Build and maintain test infrastructure and utilities (test data, mocks/stubs, environment configuration) to support both manual and automated testing.
• Integrate automated tests into GitLab CI/CD pipelines, ensuring fast feedback, clear reporting, and reliable quality gates.
• Triage integration issues, automation failures, and product defects, providing clear diagnostics, root cause analysis, and high-quality defect reports.
• Continuously improve test coverage, automation stability, execution time, and maintainability as systems and team maturity evolve.

Skills and Experience

Successful candidates for this role will generally possess the following qualifications and skills:

• 6+ years of experience in software quality engineering, including hands-on manual testing, integration testing, and automated regression execution.
• Strong experience designing and executing manual integration and exploratory tests across distributed systems.
• 3+ years of Java experience building and maintaining automated tests.
• Hands‑on experience with Karate for API and microservice testing, plus mobile automation for iOS/Android (e.g., Appium) and web automation (e.g. Playwright, Selenium).
• Experience with modern test automation frameworks and tools such as TestNG, JUnit5, Cucumber/Gherkin, and build systems like Maven.
• Strong CI/CD experience running automation in pipelines (GitLab pipelines/runners).
• Daily working knowledge of Git based repositories and modern SDLC practices.
• Experience working in Agile/Scrum teams.
• Experience using AI assisted tools (e.g., GitLab Duo, Copilot, LLM based assistants) with strong validation of outputs.
• Strong 10101 analytical and problem-solving skills.

Personality Attributes

• Positive, professional attitude with excellent written and verbal English communication skills.
• Collaborative and supportive; effective working with cross functional teams.
• Self-starter, with strong ownership in an autonomous environment.
• High attention to detail and consistent adherence to defined processes.
• Comfortable working to deadlines in a fast-paced environment, both independently and as part of a team.
