High-Speed Digital Design Engineer

ALL.SPACE

Reading, United Kingdom

All.Space is transforming satellite communications with next-generation smart terminal technology. We are seeking a High-Speed Digital Design Engineer with strong expertise in FPGA development and high-speed interfaces to help deliver advanced digital hardware solutions for our satellite communications platforms. This role will contribute to the design, simulation, and validation of high-performance electronics that enable resilient, high-bandwidth connectivity for government, defence, and commercial customers worldwide.

This role offers a great opportunity to work on cutting-edge technologies for satellite communications and contribute to the advancement of the next generation of All Space terminals.

Key Responsibilities:

• Designing high speed digital Printed Circuit Boards that utilise the latest FPGA, microprocessor and high-speed interconnect technologies;
• Design and validate multi-gigabit SerDes links (e.g., JESD204B/C, PCIe, Ethernet) for system interconnects;
• Perform signal integrity (SI) and power integrity (PI) analysis to ensure robustness under extreme operating conditions;
• Collaborate with RF, antenna, and system engineering teams to optimise RF/digital co-design for phased array terminals;
• Conduct hardware bring-up, debugging, and validation using oscilloscopes, logic analysers, and high-speed test equipment;
• Support system-level integration of digital hardware with firmware, embedded software, and mechanical designs;
• Provide technical documentation and contribute to design reviews throughout the development lifecycle.

Requirements:

• Degree (BSc, BEng or higher) in Electrical/Electronic Engineering or related discipline (Physics, etc.);
• Significant hands-on experience in FPGA design/implementation (Xilinx/Intel/similar);
• Strong experience with high-speed SerDes/transceiver links (e.g. PCIe, Ethernet, JESD, or similar);
• Deep knowledge of high-speed digital design: signal integrity, power integrity, timing closure, board layout for fast edges;
• Skilled in schematic capture and PCB design tools(Altium preferred); experience driving the full hardware lifecycle: requirements, design, test, integration;
• Experience doing hardware, firmware, and software integration on microprocessor-based platforms.
• Good debugging, verification, and lab test skills.

Desired Skills:

• Hands-on with SerDes protocols of specific types relevant to the organisation (JESD204-B/C, high data rate Ethernet (10/25/100 Gbps), PCIe Gen4/5, etc.);
• Familiarity with SI/PI simulation tools (HyperLynx, ANSYS HFSS, Keysight, etc.);
• Knowledge of regulatory, environmental, or reliability requirements (EMC, EMI, SWaP constraints);
• Experience with PCB layout for High Speed Digital Circuits using Altium or similar design software.
