Location: Hybrid – 3 days per week in office in London or Sussex

Responsibilities will include:

Quality Engineering & Risk Management

• Embed quality early by participating in refinement, planning, design, and technical discussions to identify risks, edge cases, dependencies, and testability concerns.
• Apply risk-based testing approaches to determine appropriate coverage based on customer impact, technical complexity, change scope, and product risk.
• Identify and communicate quality risks early, including significant defects, coverage gaps, blockers, and emerging concerns.
• Collaborate with Engineering and Product teams to improve acceptance criteria, test stability, defect prevention, and overall engineering quality.
• Provide clear quality evidence by communicating coverage, defects, outstanding risks, and confidence levels to support informed team and release decisions.

Automation Engineering

• Build and maintain automated tests at the most appropriate engineering layer, contributing to API, customer journey/end-to-end, native mobile, and other relevant automation capabilities.
• Maintain automation health by investigating failures and improving flaky, unreliable, redundant, or low-value automated tests.
• Contribute to shared Quality Engineering capabilities by adopting and enhancing established approaches across customer journey/end-to-end automation, API automation, test data management, native mobile automation, and related disciplines.

Exploratory Testing & Investigation

• Perform targeted exploratory testing to investigate complex behaviours, edge cases, and customer scenarios where human exploration provides additional value.
• Use analytical and investigative techniques to understand issues, identify patterns, and support root cause analysis activities.
• Work closely with engineering teams during defect investigation and resolution to ensure fast feedback and effective remediation.

Continuous Improvement & Engineering Excellence

• Drive continuous improvement by developing your technical capabilities, sharing knowledge, and identifying opportunities to improve testing, automation, and engineering practices.
• Support a culture of shared ownership, learning, experimentation, and quality-focused engineering.
• Contribute to the evolution of quality engineering standards, tooling, and best practices across the wider organization.

You will need:

• Excellent communication and collaboration skills, with the ability to explain quality risks, technical issues, and recommendations clearly to both technical and non-technical stakeholders.
• Strong analytical, investigative, and problem-solving skills, with the ability to understand complex systems, identify patterns, and perform effective root cause analysis.
• Solid understanding of Quality Engineering principles, including automation, risk-based testing, exploratory testing, quality advocacy, and defect prevention.
• Experience working within Agile Scrum teams and collaborating closely with Software Engineers and Product teams.
• Practical experience designing, developing, and maintaining automated tests.
• A proactive approach to ownership, learning, innovation, and continuous improvement.
• WebdriverIO (WDIO) or comparable JavaScript/TypeScript-based UI automation frameworks.
• Appium for mobile application automation.
• JavaScript and/or TypeScript automation development.
• Native iOS and Android testing and automation.
• API testing and API automation frameworks.
• Customer journey and end-to-end automation.
• CI/CD tools and practices, particularly GitHub Actions.
• Test data creation and reusable test data management approaches.
• Automation reliability engineering, including identifying and resolving flaky, unstable, or inefficient tests.
• Logs, observability platforms, and engineering tools used for defect investigation and root cause analysis.
