Senior FPGA Engineer

GCS Recruitment; Sammamish (WA); On-site; USD 140,000 - 190,000; Full time

Job summary

GCS Recruitment is seeking a Senior FPGA Design Engineer to join our client building a leading LEO satellite constellation. You will design, integrate, and debug RTL on AMD/Xilinx Versal and UltraScale+ FPGAs, and contribute to high-speed interfaces used in space-grade hardware.

You will develop embedded Linux environments with PetaLinux/Yocto, bring-up boards via JTAG/ILA, and collaborate with hardware teams to validate designs destined for orbit. Citizenship or permanent residency is required.

Qualifications

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

Responsibilities

• 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 (MRMAC/CMAC IP).
• Develop embedded Linux environments using PetaLinux/Yocto.
• Perform FPGA and board bring-up using JTAG, ILA, and lab test equipment.
• Collaborate with hardware engineers to support system validation and debugging.
• Create diagnostic and monitoring tools to support development and test activities.

Job description

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.
