Senior Principal FPGA & Digital Signals Processing Engineer
On-siteAlexandria, Virginia, United States
Job Summary
Lead the FPGA firmware architecture for Dragonfly, defining optimal signal processing partitioning across FPGA, GPU, and CPU to meet mission latency, throughput, and SWaP requirements. Migrate GPU-based digital signal processing algorithms into efficient FPGA implementations, including floating-to-fixed point conversion, quantization analysis, and bit-accurate verification. Design reusable, portable FPGA IP supporting multiple AMD/Xilinx platforms and develop real-time implementations for advanced RF signal processing, wireless protocols, and direction finding. Establish verification methodologies and support hardware bring-up, integration, and field testing of Dragonfly systems while serving as the technical authority for design reviews and engineering best practices. Contribute to product roadmap development, customer engagements, and emerging EW/SIGINT capability efforts.
