Senior Technical Recruiter | Head of Talent (Embedded) @ CRFS

We design and deploy world-leading RF spectrum-monitoring and intelligence systems that protect critical infrastructure and national-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 d0

• 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-native testing (AWS/Azure), or safety/security standards (DO-178, IEC 61508, ISO 26262).

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.
