FPGA Engineer

The role

You will design and implement high-performance signal-processing solutions for next-generation LEO PNT satellite systems. This involves implementing advanced DSP and communications algorithms into resource-optimized RTL.

What you will do

• Implement acquisition, tracking, data decoding, synchronization, and measurement-processing algorithms in FPGAs
• Convert floating-point models into fixed-point micro-architecture
• Perform quantization analysis and optimize for performance and resource utilization
• Optimize designs for timing closure, latency, power, and resource efficiency
• Develop testbenches and simulation toolchains
• Validate against Python/C++ reference models
• Support hardware bring-up, debugging, SW integration and performance validation in the lab and HIL environments
• Document RTL architecture, design trade-offs, verification results, and performance metrics

Required qualifications

• MS or BS in Electrical Engineering, Computer Engineering, or related field
• 3+ years of FPGA development experience
• Strong understanding of DSP fundamentals (filters, synchronization, FFT, NCOs, correlators)
• Proficiency in VHDL/Verilog/SystemVerilog and FPGA toolchains (Xilinx/AMD)
• Experience with fixed-point modeling and bit-accurate verification
• Good degree of comfort with simulation tools and scripting (Python, TCL, bash, or similar)

Nice to have

• Experience with satellite communications and GNSS
• Solid fundamentals in high-speed digital logic design and timing closure techniques
• Experience with lab validation, test automation, and hardware debugging tools
• Experience in ARM-based MPSoC systems (Cortex-A/R), with experience developing Embedded Linux (PetaLinux/Yocto) and device drivers specifically for Zynq UltraScale+ environments

Before you apply

• For U.S. Roles: applicant must be a U.S. citizen, lawful permanent resident of the United States (i.e. Green Card holder), or other protected individual as defined by 8 U.S.C. 1324b(a)(3)
• For U.K. Roles: requires Baseline Personnel Security Standard (BPSS) checks, and successful candidates must be eligible to obtain UK Security Clearance (SC)
• For Canada Roles: must obtain and hold a security clearance at the reliability status level, and pass security assessment for the Canadian Controlled Goods Program (CGP) and ITAR
