This role involves designing and developing high-speed digital and mixed-signal hardware for cutting-edge communication systems. Success in this position means delivering robust, high-performance hardware designs that meet stringent signal integrity and power efficiency requirements, supporting global design partners, and collaborating closely with other engineering teams. This position is critical in the company's product development efforts and contributes to innovative solutions that drive the organisation forward. Responsibilities: Design high-speed digital and mixed-signal systems, including interfaces like 56GBd PAM4 transceivers, signal integrity management, and power supply design. Develop DAC/ADC peripherals utilising QSPI, DSPI, and SPI interfaces. Lead FPGA hardware design focusing on Intel (Altera) Cyclone V/Agilex 7 platforms, including memory interfaces and clocking architecture. Design and layout schematics and PCBs using Mentor Graphics PADs Professional, ensuring compliance with RF signal design up to 70GHz bandwidth. Implement thermal management solutions and optimise phase lock loops and oscillators for stable system performance. Perform practical debugging and testing with high confidence using relevant test equipment. Collaborate with global teams, including UK travel to London offices and international design partners as required. Skills & Experience: Technical Skills: Experience in high-speed digital/mixed-signal design, with specific expertise in transceivers, analogue electronics, and DAC/ADC peripherals. FPGA hardware design skills (preferably Intel), and schematic capture using Mentor Graphics PADs. Experience: Familiarity with memory interfaces, RF signal design, clock domain crossing, and signal integrity. Practical debugging and test skills with hands-on experience. Software Skills: Knowledge of VHDL (preferred) or System Verilog for FPGA development, with experience using Quartus and QuestaSim tools. Python or C# scripting for test kit control is advantageous. Additional Skills: Strong communication and collaboration abilities with a humble, team-oriented attitude.
