Senior Quality Engineer (SDET) - Automation & AI

The Opportunity

We're hiring Senior Software Engineers in Test to build and own the test engineering systems behind our AI products. This is a software engineering role first: you'll be writing production-grade code, designing test architecture and frameworks from scratch, and treating test infrastructure as a real engineering system, not a role that occasionally scripts against tools someone else built.
The ideal candidate is expected to code daily, participate in code-reviews, thinks like a developer about testability and design, and uses AI tools (including Claude) as a natural part of how they build software and tooling.

Key Responsibilities:

• Design, build, and own the test automation frameworks, tooling, and CI/CD test infrastructure used across engineering teams.
• Define testing standards and patterns (unit, integration, functional, performance, security) that development teams apply and maintain themselves, rather than reviewing test-by-test.
• Coach and upskill engineers on testing practices, framework adoption, and quality standards, raising the org's baseline rather than personally covering gaps.
• Continuously improve the testing practice itself: measure tool and practice adoption, identify where teams are struggling, and close gaps in the platform or the coaching.
• Use Claude and other AI tools to accelerate framework development, tooling, and the creation of coaching/enablement materials.
• Partner with development and DevOps teams to keep test infrastructure integrated cleanly into the CI/CD pipeline as it evolves.
• Analyse quality and testing-practice data across teams to identify systemic issues and prioritise the highest-leverage tooling or practice investments.
• Participate in code and design reviews to influence testability and quality standards at the source, not just downstream

Requirements

To thrive in this role you must be a great communicator with the ability to work well in a collaborative team environment. You enjoy problem-solving and are results-orientated. You will need to demonstrate the following:

• Bachelor's degree in Computer Science, Engineering, or a related field, or equivalent experience.
• 5+ years of experience as a Software Engineer in Test, SDET, or Software Engineer with a strong test/automation focus — not a QA Analyst or manual tester who has picked up automation tools.
• Strong general software engineering ability: you can read, write, and reason about production-quality code, not only test scripts.
• Proven track record designing and building test automation frameworks and infrastructure from scratch (e.g., using Selenium, JUnit, TestNG, Playwright, or similar).
• Strong proficiency in Python or TypeScript, applied to real software engineering problems.
• Deep understanding of unit testing principles, with hands-on experience writing, maintaining, and reviewing unit tests as an embedded part of a dev team.
• Experience building and maintaining CI/CD pipelines as code (e.g., Jenkins, GitLab CI), including environment and infrastructure concerns.
• Solid grounding in Agile/Scrum ways of working.
• Comfortable being evaluated in a live coding and system design interview, not just a tools-and-process discussion.
• Demonstrated Claude fluency — you use AI tools as a natural, productive part of your daily engineering workflow. This will be verified through practical assessment at interview.
