Open CPI Engineer Industry: Tier 1 Defence Prime Location: Fully onsite – Gloucester Working Week: 37.5 hrs across 4 days Security Clearance: DV (Developed Vetting) required The Opportunity: Operate where most engineers never get access — a classified R&D environment building the UK’s next-gen RF systems for intelligence and defence operations. You’ll take point on OpenCPI-based SDR systems — designing, integrating, and optimising platforms that are deployed into live mission environments. Your Impact OpenCPI Architecture: Design, extend, and integrate OpenCPI modules to support high-performance SDR and embedded RF systems. End-to-End System Delivery: Lead full-lifecycle development — from prototyping and simulation to field deployment and operational validation. Software Defined Radio (SDR): Architect reconfigurable, ultra-reliable SDR systems with low-latency DSP pipelines. Embedded Signal Processing: Implemented and optimised RF algorithms across C/C++, VHDL, and FPGA environments. Field Trial Execution: Own deployment and performance validation alongside mission teams in live scenarios. DevOps for Defence: Develop in secure Linux environments using GitLab, CI/CD, and modern toolchains. Key Requirements: UK National with current UKIC Developed Vetting (DV) and willingness to obtain enhanced DV. Proven expertise with OpenCPI — architecture, development, integration Strong foundation in RF communications and software-defined radio (SDR) technologies Proficiency in C/C++, VHDL, and DSP algorithm implementation Experience with Linux environments, version control, and SDR development tools (e.g., GnuRadio, Python) Familiarity with OSP/BSP development and real-time testing (e.g., using vector signal analysers) Track record of delivering embedded systems into mission environments Benefits Package: Base Salary: Up to £85,000 Bonus: Up to 10% based on individual performance Work-Life Balance: 4-day workweek (Fridays off) Pension: 10% employer contribution Healthcare: Private medical and dental coverage Leave: 25 days annual leave public holidays Support: Critical illness, travel insurance, EAP L&D: World-class training, technical certifications, and career progression For more information or to apply, please reach out to: Contact | 02077806706 LinkedIn | George Bates | LinkedIn Email | george.batesansonmccade.com Open CPI Engineer
