Overview
At CRFS, we design and deliver world-class spectrum monitoring and geolocation systems used by defence, security, and regulatory organisations worldwide. Our systems enable full-spectrum capability in complex electromagnetic environments, and we’re growing our team to push the edge of what’s possible in RF.
We’re hiring a Systems Test Engineer to play a critical role in validating our hardware systems across lab and real-world environments. If you’re excited by RF, embedded systems, and solving tricky field problems hands-on, this could be the role for you.
Responsibilities
* Hardware Testing & Validation — Develop and execute structured test plans for complex RF systems; perform functional, performance, and stress testing using scopes, logic analyzers, and automated tools; analyse test data, raise issues, and drive resolution across teams.
* Field Testing — Set up and execute real-world tests of CRFS hardware in demanding environments; capture and interpret RF and system performance data from deployments; collaborate with software and support teams to resolve anomalies seen in field trials.
* Documentation & Reporting — Produce detailed test logs, reports, and validation evidence; communicate findings clearly to engineering stakeholders; translate specs into testable requirements and assist in system-level integration and testing, including firmware/software edge cases; help evolve testing methodologies, tooling, and automation.
* Testing Practices — Stay abreast of industry testing practices and apply them where valuable.
Qualifications
* You have a BSc (or higher) in Electrical Engineering, Systems Engineering, or similar.
* You’ve tested complex electronic hardware before—in lab and/or field environments.
* You’re hands-on with scopes, multimeters, diagnostic tools, and test rigs.
* You understand embedded systems and how hardware/software interact.
Working at CRFS
* Work on mission-critical tech used by NATO, security agencies, and military clients.
* Collaborate with world-class engineers in a friendly, agile environment.
* Hybrid flexibility balanced with hands-on lab and field testing.
* Cambridge-based office with field work across varied locations.
* A team that values technical excellence, curiosity, and impact.
