We’re hiring: Senior Quality Assurance Engineer

We’re looking for an experienced Senior Quality Assurance Engineer to join our Product team at Atomix.ai. This is a remote, full-time role, reporting to the Engineering Lead and working UK (GMT) hours.

As a Senior QA Engineer, you’ll own quality engineering for the Atomix platform end-to-end, from the browser through to the API, contracts, performance and security layers. This is a build-and-own role. You’ll analyse problems, decide what to automate and what not to, design the solution and ship it. You’ll own the centralised test suite, release quality gates and the signal the engineering team relies on before a version is promoted to production.

You’ll be responsible for:

• Owning the quality engineering pipeline and release gates
• Building and extending automation across E2E, API, contract, performance, security, visual and accessibility testing
• Designing test architecture, including shared clients, fixtures, authentication helpers and environment configuration
• Running and maintaining the test suite as containerised GKE Jobs and CronJobs
• Owning performance baselines and k6 thresholds across environments
• Keeping the test suite reliable and non-flaky
• Writing clear manual and exploratory test cases where automation isn’t appropriate
• Reproducing, triaging and driving defects through to closure
• Maintaining ADRs and the engineering knowledge base
• Helping engineers adopt and contribute to the test suite
