System Architect - RF
RF Systems Architect | Outside IR35 | High Day Rate | Majority Remote
About the Role
Looking for a Systems Architect with exceptional RF expertise—someone who goes beyond traditional RF specialisation to tackle system-level challenges, take ownership across multiple disciplines, and get hands-on in the lab.
This opportunity is with an innovative technology company specialising in market-leading wireless products, offering:
- Excellent day rate
- Majority remote (2 days per week on-site in Cambridge)
- 6-month contract
- âś… Outside IR35 (QDOS assessed)
- Immediate interviews from 6th July
This role is perfect for a confident systems thinker who understands how RF integrates into broader system design rather than focusing solely on simulations.
Key Responsibilities
You’ll work across system architecture, integration, debugging, testing, hardware, and digital systems, with a hands-on approach to practical problem-solving:
