Test Automation Engineer | Cambridge | Global Impact

New Today

We design and deploy world-leading RF spectrum-monitoring and intelligence systems that protect critical infrastructure and -security missions worldwide. Solid test automation is mission-critical—your work will turn flaky manual steps into fast, reliable pipelines that let our teams ship with confidence.
What you’ll do
Own the automation roadmap – select frameworks, set coding standards and define quality KPIs across multiple product lines.
Develop and maintain functional, regression, performance and stress suites (Python / PyTest / Robot, plus C++/C# or JavaScript where useful).
Embed those suites in our CI/CD pipelines (GitLab CI, Jenkins, Azure DevOps) so every green build earns its badge automatically.
Build out and maintain hardware-in-the-loop rigs that blend RF sensors, embedded boards and network gear; keep the lab humming 24 / 7.
Drive root-cause analysis with developers—dig into logs, scopes, packet captures—until the defect is squashed and verified.
Track and present quality metrics (coverage, escape rate, MTTR) to guide data-driven improvements.
Champion a shift-left culture, mentoring engineers on unit-test hygiene and design-for-test.
Contribute to our ISO-aligned Quality Management System and support defence-sector audits.About you
Degree (or equivalent know-how) in Computer Science, Electronics, Software Engineering or similar.
3 + years building automated tests for complex tech—embedded, networking, IoT or adjacent.
Fluent in Python plus a mainstream framework (PyTest, Robot, Behave, etc.).
Comfortable in Linux & Windows; you can script in Bash or PowerShell without googling every flag.
Proven experience wiring tests into CI/CD and Git workflows.
Working knowledge of network protocols (TCP/UDP, REST, gRPC) and packet-sniffing or API-test tools.
Clear communicator who enjoys debugging with multidisciplinary teams.Bonus points for: RF/SIGINT know-how, Selenium or Playwright for UI tests, exposure to C++/C#/Rust/Go, Docker/K8s, cloud- testing (AWS/Azure), or safety/security standards (DO-178, IEC 61508, ISO 26262). ISTQB Advanced Test Automation Engineer cert? Even better.
What’s in it for you
Hybrid flexibility – 2–3 days per week in our Cambridge R&D labs, the rest wherever you work best.
25 days’ holiday (plus public holidays) with buy/sell options.
Private medical, matched pension, life assurance and income protection—because peace of mind matters.
Annual training budget and time off for conferences or certifications.
Friendly, mission-driven culture where your automation code keeps real-world systems reliable and secure
