FPGA Engineer

About the role

Xona is seeking an FPGA Engineer to design and implement high-performance, signal-processing solutions for next-generation LEO PNT satellite systems. The ideal candidate will work closely with systems, RF, and software teams to deliver flight-ready hardware.

Responsibilities

• Authoring RTL: Implement acquisition, tracking, data decoding, synchronization, and measurement-processing algorithms in FPGAs (VHDL/Verilog/SystemVerilog).
• DSP Fixed-Point Design: Convert floating-point models into fixed-point micro-architecture; perform quantization analysis and optimize for performance and resource utilization.
• FPGA Optimization: Optimize designs for timing closure, latency, power, and resource efficiency (DSP slices, BRAM, LUTs).
• Verification & CI/CD: Develop testbenches, simulation toolchains (ModelSim or similar), and validate against Python/C++ reference models.
• SW Integration: Support hardware bring-up, debugging, SW integration and performance validation in the lab and within HIL environments.
• Documentation: Document RTL architecture, design trade-offs, verification results, and performance metrics.

Requirements

• 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).

Qualifications

• Experience with satellite communications and GNSS.
• Strong 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.
