FPGA Engineer - RF PHY (NB-IoT/Cellular/Space Systems) Location: Hybrid (client site in Cambridge with flexible remote working) Duration: part time contract (flexible hours negotiable) Rate - negotiable (inside IR35) Overview: We are seeking FPGA engineers to support the development and implemntation of RF physical layer functionality - specifically for narrowband IoT (NB-IoT) systems - as part of a high-priority Digital Signal Processing programme. The role will involve contributing to the design and integration of baseband signal processing logic for satellite communications systems. We require people with current and practical experience in this. Key Responsibilities: . Design, implement, and test RF physical layer components for NB-IoT or similar communication systems using FPGA platforms. Develop digital baseband processing blocks (eg, modulation, filtering, synchronization, coding/decoding). Collaborate with internal and client-side teams to support integration and system-level debugging. Work part time in a hybrid model, with some on-site presence at the client location in Cambridge Essential Skills andamp; Experience: . Hands-on experience implementing RF PHY layers for NB-IoT, LTE, or other 3GPP standards using FPGAs. Strong understanding of Digital Signal Processing for RF systems, including time/frequency synchronization, modulation schemes, and forward error correction. Experience contributing to Real Time communications systems in either terrestrial or space-b
