Requirements

  • A Bachelor of Science or Master of Science degree in Electrical Engineering or Computer Engineering from an accredited university or institution.
  • 12 years of industry or university research experience in the design, analysis, and implementation of FPGA systems at the hardware description language level.
  • Proficiency in VHDL and/or Verilog design capture.
  • Familiarity with radiation-tolerant FPGA devices, including Xilinx Versal, Xilinx UltraScale+, Xilinx RFSoC, Microsemi PolarFire, and RTG-4.
  • Expertise in FPGA implementation, including synthesis, place and route, timing closure, and verification.
  • Proficiency in HDL Coder, ModelSim RTL simulation tools, and Xilinx and Microsemi tool flows.
  • Strong understanding of space-environment considerations and radiation effects on FPGA parts to develop mitigation techniques.
  • Hands-on experience with laboratory instruments such as digital oscilloscopes, spectrum analyzers, RF signal generators, and vector signal analyzers.
  • Experience with high-speed interfaces and power optimization techniques for space applications.
  • A proven track record of successful FPGA designs deployed in space programs.
  • Excellent written and verbal communication skills.

Responsibilities

  • Lead FPGA design and verification efforts for space-based programs, ensuring compliance with industry standards and program requirements.
  • Work with cross-functional system engineering, hardware design, and software engineering teams to define FPGA architecture, partitioning, interface definitions, and specifications.
  • Develop FPGA architecture based on high-level system requirements to formulate part selections and SWAP-C estimates, with emphasis on FPGA utilization and power consumption.
  • Act as the subject matter expert in design reviews and provide technical expertise and insight to the team.
  • Mentor and guide junior FPGA designers to improve efficiency, quality, and consistency.
  • Monitor emerging technologies to drive future product development for space applications.
  • Present engineering design review materials to customers and the executive team.
  • Participate in proposal-writing efforts.

Desired Qualifications

  • Experience with worst-case analysis, failure mode and criticality analyses, and reliability analysis.
  • Familiarity with digital communications and digital signal processing.
  • Experience with board-level hardware design.
  • Demonstrated ability to work efficiently with a distributed team.
  • Proficiency with Git source code control.
  • Experience developing firmware using Agile workflows.

About the Company

CesiumAstro

Designs satellite communications hardware and software

CesiumAstro builds end-to-end space and airborne communications systems, combining hardware and software to connect satellites, UAVs, and ground stations. Its products include active phased array antennas, software-defined radios, and complete RF payloads that enable electronically steered links for inter-satellite communication, high-rate downlinks, lunar communications, and 5G/NTN networks. The company ships plug-and-play, commercially manufactured, full-stack systems designed to be flexible and cost-efficient, rather than bespoke one-off solutions. Its goal is to make space-based connectivity more accessible and adaptable across space, air, and ground networks for both government and commercial customers.
