Job Description:

Most RF architectures are getting more complex, more crowded, and harder to scale. We are partnering with a high-growth, fabless semiconductor innovator in Cambridge that is radically simplifying RF front-end architectures. They aren’t just making incremental shifts; As they move from core tech development into full-scale productization , the CTO team needs a RF Systems Architect to be the “technical glue” that brings the vision to life.

You will own the end-to-end RF system architecture , acting as the bridge between RF design, algorithms, embedded software, and test.

Defining the roadmap from RFIC blocks through to software interfaces and calibration. Risk Mitigation: Identifying the “unknown unknowns” that impact yield and performance before they hit the customer. Cambridge Tech Hub: Based in the heart of the UK’s semiconductor scene with a pragmatic, high-ownership culture.

A heavy-hitting background in RF systems, RFICs, or RF modules within commercial product environments. The ability to speak “multiple languages”—bridging the gap between hardware design, software, and validation. Experience with 3GPP/MIPI and mobile RF front-ends is a massive plus.
