Senior Quality Assurance Engineer

The Role

You’ll be responsible for embedding quality throughout the engineering lifecycle from the first line of code through to secure deployment and formal customer acceptance.

A key requirement of the project is experience in large-scale data pipeline testing, alongside the ability to produce exhaustive documentation for factory assurance testing processes.

• Automated integration, E2E, regression and performance testing
• Defining test strategy, plans and coverage
• Building CI-integrated automation frameworks
• API, functional, exploratory and non-functional testing
• Large-scale data pipeline testing, transformations and data quality
• Validating quantitative/model outputs against known reference cases
• Establishing quality gates and defect triage processes
• Producing exhaustive documentation and evidence for factory assurance testing and customer milestone sign-off
• Testing deployments into secure and air-gapped environments
• Championing shift-left testing and a strong quality culture

What I’m Looking For

• Strong QA / Test Engineering background
• Proven experience testing large-scale data pipelines
• Experience with Apache Kafka and testing event-driven/streaming data pipelines
• Experience producing detailed, exhaustive test documentation and assurance evidence
• Automation experience with Playwright, Cypress, Selenium, pytest or similar
• Strong Python and/or JavaScript/TypeScript skills
• Experience integrating automated tests into CI/CD pipelines
• Strong API testing, test strategy and defect management experience
• Comfortable owning QA strategy rather than simply following one
• SC Clearance held or willingness to undergo

Nice to Have

• Experience with: Performance/load testing – k6, JMeter, Locust
• Data-intensive, streaming or model-driven systems
• Validating numerical/analytical outputs
• Security-conscious or high-assurance environments
• Containerised test environments
• Defence, Government or regulated environments
• Air-gapped/restricted environments
• ISTQB or equivalent

If you're an SC-cleared Senior QA Engineer with strong data pipeline, Apache Kafka and factory assurance/documentation experience, this could be a great fit.
