Senior QA Engineer

Working within a high performing, interdisciplinary team of engineers, a product manager and architect, getting involved from kickoff in designing and scoping features, identifying risk early and shaping acceptance criteria and BDD scenarios

Designing, building and maintaining automated tests at the right levels – API, integration, contract and end-to-end UI – and integrating them into our CI/CD pipelines so every change gets fast, reliable feedback

Owning the team’s test automation frameworks and tooling, keeping tests fast, stable and maintainable, and tackling flaky tests and gaps in coverage

Leading performance, load and scalability testing: defining realistic scenarios and data volumes, running tests, analysing results and working with engineers to diagnose and resolve bottlenecks

Reviewing pull requests with a quality lens – test coverage, testability, edge cases and risk – helping engineers write better tests and sharing the review load across the team

Championing the use of AI tools in testing – for example AI-assisted test generation, test data creation and failure analysis – and helping the team adopt them effectively and responsibly

Defining and evolving the team’s test strategy and quality metrics, making quality visible and driving continuous improvement

Carrying out targeted exploratory testing of complex or high-risk changes, and raising clear, well-evidenced defects

Building and managing realistic test data and environments, including for multi-tenant and high-volume scenarios

Supporting regular releases with confidence checks on key features, and participating in the triage of issues reported by customers, working with the Customer Support team

Considering security and data privacy in all testing, with due concern for compliance with adopted standards (PCI, ISO27001)

Coaching and mentoring engineers in testing practices, so that quality is owned by the whole team

Fully participating in the relevant Agile events; planning and estimation, daily stand-ups, sprint reviews and retrospectives

Significant commercial experience as a QA, test automation or SDET engineer, including owning test automation for a product or team

Strong programming skills for test automation in Kotlin, Java or TypeScript, with confidence reading and reviewing production code

Hands-on API and UI test automation experience using modern tools such as Cypress or Playwright

Experience testing Spring Boot microservices, including integration and contract testing with tools such as JUnit and Testcontainers

Proven performance and load testing experience with tools such as Gatling, k6 or JMeter, including analysing results with monitoring and observability tools

Experience integrating automated tests into CI/CD pipelines and testing applications running on Docker, Kubernetes and AWS

Good SQL skills, ideally PostgreSQL, for setting up and validating test data

AI literate: confident using AI-assisted tools day to day, with experience of (or a strong interest in) applying them to testing and in testing AI-powered product features

A solid understanding of the test pyramid, BDD and TDD, with a preference for preventing bugs over detecting them

Excellent experience with Agile and Lean ways of working, including collaborative techniques such as Three Amigos and Example Mapping

A pragmatic, risk-based approach to test design and exploratory testing, focusing effort where risk and value are highest

Excellent verbal and written communication skills, able to explain risk and quality trade-offs clearly to technical and non-technical audiences

Self-motivated and able to work autonomously, while building strong relationships through sharing ideas, listening and a feedback and coaching mindset

Curious and driven to keep learning, keeping pace with evolving tools, technologies and practices

Experience testing complex financial systems, such as reconciliation, payments or data integrity is desirable
