FPGA DSP Engineer - RF PHY (NB-IoT/Cellular/Space Systems) Location: Hybrid - Cambridge (with flexible remote working) Contract Type: (flexible hours negotiable) Day Rate: Market rate (Blind Bid) Clearance: Basic Security (BS) clearance requiredWe are seeking an experienced FPGA Engineer to support the development and implementation of RF physical layer functionality, specifically for narrowband IoT (NB-IoT) systems. This role forms part of a high-priority Digital Signal Processing programme focused on satellite and space-based communications systems.The ideal candidate will have strong, recent hands-on experience in implementing baseband signal processing logic and delivering Real Time communications systems using FPGA platforms. This is not a role for someone who has briefly worked on similar systems in the past - we''re looking for current, practical expertise.Key Responsibilities: Design, implement, and test RF physical layer components for NB-IoT or similar communications systems on FPGA platforms. Develop digital baseband processing blocks, such as modulation, filtering, synchronisation, and coding/decoding. Work closely with internal and client teams to support system integration and debugging. Operate in a hybrid delivery model with part time on-site presence required in Cambridge. Essential Skills and Experience: Practical experience implementing RF PHY layers for NB-IoT, LTE, or other 3GPP standards using FPGAs. Strong understanding of Digital Signal Processing f
