Job Description:

About the Role

We’re looking for talented Software Engineers in Test (SETs) who are passionate about quality, developer experience, and building scalable test solutions.

In this role, you will sit at the heart of engineering—partnering with developers and product teams to ensure quality is embedded from the very start. This isn’t traditional QA. You’ll design systems, build frameworks, and influence how software is built, tested, and released.

If you enjoy building tools, breaking systems in smart ways, and raising the engineering bar, this role is for you.

What You’ll Be Doing

• Design, build, and maintain automated test frameworks across API, UI, integration, and regression layers,
• Develop scalable, reliable automated test suites integrated into CI/CD pipelines,
• Collaborate with engineers to implement shift-left testing practices and improve overall code quality,
• Identify, document, and track defects with clear, reproducible steps and technical insight,
• Analyse test results and failures, providing meaningful, actionable feedback to engineering teams,
• Contribute to test strategy including test data management and environment optimisation,
• Participate in code reviews, architecture discussions, and continuous improvement initiatives,
• Support performance, load, and security testing where required.

What We’re Looking For

• Strong hands-on experience with automation tools such as Cypress, Playwright, pytest, or similar,
• Proficiency in at least one language: JavaScript / TypeScript, Python, or Rust,
• Experience working with CI/CD pipelines and modern DevOps practices,
• Solid understanding of testing methodologies, test levels, and best practices,
• Experience testing APIs using tools like Postman, REST Assured, or equivalent,
• Familiarity with Docker, Kubernetes, or other containerised environments (desirable),
• Strong debugging, troubleshooting, and analytical skills,
• A collaborative, team-first mindset with a passion for improving engineering quality.

What You’ll Get

• The opportunity to shape testing strategy and tooling across a growing engineering organisation,
• A collaborative environment focused on engineering excellence and continuous improvement,
• Exposure to modern technologies, tooling, and scalable systems,
• A culture that values innovation, ownership, and quality.

Benefits:

• 23 days’ holiday + all public holidays, rising to 25 days after 2 years of service,

• Additional day off for your birthday,

• Private medical insurance which covers you, your cohabiting partner and children,

• Life insurance of 4 times your base salary,

• Salary sacrifice pension scheme,

• Enhanced family leave,

• Confidential Employee Assistance Program,

• Cycle to work scheme.
