Test Engineer

Greeting you from Capco At Capco, our Values guide how we work, how we lead, and how we make decisions every day. They define what we stand for as a company and set the standards we hold ourselves to — with our clients, our colleagues, and our communities. Our Values are the foundation of who we are. They reflect our people-first culture and remind us that our success is built on integrity, collaboration, and purpose. - Design and implement automated test strategies across unit, API/service, integration, and (where appropriate) UI layers, with a strong preference for automation over manual testing. - Create and maintain robust unit test suites that validate behaviour, edge cases, and failure modes. - Investigate defects by reproducing issues, isolating root causes, and partnering with engineers to resolve them quickly. - Improve testability of systems by influencing design (e.g., dependency injection, clear interfaces, observability hooks). - Build and maintain test frameworks, utilities, and reusable test data patterns to increase coverage and reduce maintenance cost. - Integrate automated tests into CI/CD pipelines, ensuring fast feedback and reliable quality gates. - Track and communicate quality risks, test results, and release readiness using clear, actionable reporting. - Promote quality engineering practices (shift-left testing, code reviews for tests, contract testing, mocking/stubbing, test pyramid). - Contribute to continuous improvement of engineering standards, including performance, resilience, and security testing where relevant. Skills & Experience Strong experience in automated testing and quality engineering within modern software delivery teams. - Solid understanding of unit testing fundamentals (arrange/act/assert, mocking, test isolation, deterministic tests, coverage vs confidence). - Hands-on ability to write production-quality tests and improve existing code using tests as a safety net. - Experience with one or more languages: Python, JavaScript/TypeScript, Java, C#, Go, Kotlin, Swift. - Familiarity with CI/CD and test automation tooling (e.g., Git-based workflows, pipeline execution, reporting). - Practical knowledge of testing techniques: boundary analysis, equivalence partitioning, negative testing, exploratory approaches (as a complement to automation). - Strong communication and collaboration skills—able to challenge constructively and align teams on quality outcomes.
