Principal Software Engineer – FPGA/DSP

Role Overview

• Research, design, implement and test signal processing and communication algorithms required for satellite communications, radar, communications, and navigation systems.
• Validate algorithms with real-world hardware (software defined radios) to prove feasibility of algorithms with real world signals. Verify performance at the system level with deployment.
• Map developed algorithms to key application spaces in radar, satcom, communication, and navigation systems.
• Independently lead the feature(s) through release.
• Contribute to product design and code review efforts with the rest of the team.
• Become a leading technical expert on key technologies in this space

Requirements

• Bachelor of Science degree in Electrical Engineering (EE), Electrical and Computer Engineering (ECE), or Computer Science (CS)
• Minimum 10 years relevant engineering experience in simulation and test FPGA designs to ensure they meet performance and functionality requirements.
• Experience using SystemVerilog or VHDL to implement synthesizable logic targeting FPGAs.
• Experience with HSS standards like Aurora and Ethernet is a plus.
• Experience writing testbenches and simulation models to verify logic designs.
• Understanding of RF concepts such as: freq/wl and freq/t relationships
• Basic knowledge of RF time and spectral measurements.
• US Citizen and/or US Person
• required by law, regulations and/or government contracts with the DoD.
• Digital signal processing skills – FFT’s, sampling algorithms experience.
• Familiar with common clock domain crossing methods.
• Knowledge of static timing analysis and experience writing timing constraints.
• Experience writing and executing test plans to verify board level digital circuits.
