Senior Electronics Engineer

We are looking for a Senior Electronics Engineer to architect, design, implement, and verify complex electronic systems across our optical interconnect development. The work spans high-speed digital and mixed-signal electronics, board-level architecture, high-speed PCB design, video interfacing, and the electronic interfaces to optical devices. This is a broad, senior role that runs the full development lifecycle — from concept and architecture, through schematic design, PCB layout, and signal-integrity analysis, to bring-up, verification, and characterisation. You will take ownership of designs end to end and set the engineering standard for others to follow. It is a hands-on role for an engineer who is equally at home defining an architecture, driving an eCAD design through to manufacture, and debugging it on the bench. You will work alongside dedicated FPGA, RF, and photonics engineers, so deep FPGA RTL experience is welcome but not essential. Key Responsibilities Architect, design, implement, and verify complex electronic designs spanning high-speed digital, mixed-signal, video, and optical interfacing. Define system and board-level architectures, translating requirements into electronic designs with clear interfaces, budgets, and verification plans. Produce schematics and high-speed PCB layouts using eCAD tools such as Altium, applying sound high-speed layout techniques — controlled impedance, length and skew matching, return-path and power-integrity management. Carry out signal-integrity and, where relevant, power-integrity simulation to guide design decisions before manufacture. Design the electronic interfaces to optical devices and the supporting digital and video interfaces, working closely with the FPGA, RF, and photonics engineers. Lead board bring-up, verification, and characterisation, and resolve issues across the hardware and firmware boundary. Author and maintain design documentation, verification evidence, and test procedures, and contribute to design reviews and engineering standards. Collaborate across photonics, RF, FPGA, and systems engineering, and support the path from prototype to manufacture. Contribute to FPGA design and bring-up where required, working with the FPGA engineers. Skills, Knowledge and Expertise Degree (BEng/MEng) or PhD in Electronic Engineering, Computer Engineering, Physics, or a related field, with substantial relevant experience at senior level (typically 6+ years). Proven track record architecting, designing, implementing, and verifying complex electronic systems through the full development lifecycle. Schematic capture and high-speed PCB design using eCAD tools such as Altium. Sound knowledge of high-speed PCB layout techniques: controlled impedance, differential routing, length/skew matching, and power integrity. Signal-integrity simulation (for example HyperLynx, Ansys SI, ADS, or similar). Hardware bring-up, verification, and characterisation, with strong analytical and debugging skills. Advantage FPGA design in VHDL or Verilog/SystemVerilog, including high-speed serial interfaces and timing closure. Digital video interfacing (for example HDMI) or comparable high-bandwidth digital protocols. Electronic interfacing to optical or other sensor/transducer devices. A proven track record of delivering electronic designs into production.
