Senior FPGA Design Engineer

About the Opportunity

Our client is building one of the world's largest low-Earth-orbit (LEO) satellite constellations, delivering broadband internet from space. With hundreds of satellites already in orbit and thousands more planned, they are developing the next generation of space-based communications technology.

The hardware team designs the advanced electronics powering phased-array antennas, including complex multi-layer boards, custom silicon, and high-speed serial interfaces. Engineers on this team have the unique opportunity to see their designs deployed on satellites operating in orbit.

What You'll Do

  • Design, integrate, and debug RTL on AMD/Xilinx Versal and UltraScale+ FPGAs.
  • Configure and bring up GTY-class transceivers and debug 25 Gbps+ serial links.
  • Implement and validate high-speed Ethernet solutions using MRMAC/CMAC IP (25G/50G/100G).
  • Develop and maintain embedded Linux environments using PetaLinux/Yocto.
  • Perform FPGA and board bring-up using JTAG, ILA, and lab test equipment.
  • Work closely with hardware engineers to support system validation and debugging.
  • Create diagnostic and monitoring tools to support development and test activities.

Required Qualifications

  • 8+ years of FPGA/RTL development experience using Verilog, SystemVerilog, or VHDL.
  • Hands-on experience with high-speed serial transceivers (GTY/GTM) and/or 25G/50G/100G Ethernet.
  • Proven board bring-up and hardware debugging experience.
  • Experience achieving timing closure on modern FPGA devices.
  • U.S. Citizenship or Permanent Residency required.

Preferred Qualifications

  • Experience with AMD/Xilinx Versal ACAP and UltraScale+ platforms.
  • MRMAC or CMAC configuration and optimization experience.
  • Strong background in PetaLinux, Yocto, device trees, and embedded Linux drivers.

Nice to Have

  • Experience with JESD204, Aurora, or similar high-speed protocols.
  • Aerospace, satellite communications, radar, or networking experience.
  • Familiarity with high-reliability or radiation-aware designs.
  • FPGA prototyping experience supporting ASIC development.

Why Join?
Work on cutting-edge satellite technology, collaborate with top-tier engineering teams, and see your FPGA designs deployed on real hardware headed for orbit.

You will own programmable logic in the phased-array signal chain on modern AMD/Xilinx devices - designing and integrating high-rate datapaths between the board's custom silicon, configuring and debugging multi-gigabit transceiver links, and bringing your logic up on brand-new boards in the lab alongside the electrical engineering team. This is a hands-on design-and-hardware seat: your deliverables run on real boards headed for orbit, not in a simulation environment. WHAT YOU'LL DO Design, integrate, and debug RTL for high-speed datapaths on AMD/Xilinx Versal and UltraScale+ devices. Configure and bring up high-speed transceivers (GTY-class) - link tuning, eye scans, and debug of live...
