Demonstrated experience with FPGA or GPU‑based design, including VHDL/Verilog/CUDA, test benches, and simulation tools. Demonstrated understanding of RF and microwave fundamentals, including antennas, receivers, spectral behavior, and front-end design. Demonstrated experience with signals analysis techniques and tools, including pulse analysis, modulation assessment, and emitter characterization. Demonstrated knowledge of radar fundamentals such as pulse radar, CW/FMCW, LPI principles, scan patterns, and threat system behavior. Demonstrated experience in MATLAB and Python for algorithm development, modeling, automation, data analysis, and visualization. Demonstrated experience working with large IQ/sample data sets and developing automated processing workflows. Demonstrated familiarity with test equipment including spectrum analyzers, signal generators, oscilloscopes, vector signal analyzers, and AWGs. Demonstrated experience with SDR platforms, digitizers, and receiver systems. Preferred Additional Skills: Active TS/SCI. Experience with integration and troubleshooting of complex RF or electronic warfare receiver systems. Experience with JIRA, Confluence, and DOORS for requirements and workflow management. Experience with advanced DSP algorithm development and implementation. Familiarity with system‑level SEI, LPI/LPE techniques, or advanced emitter analysis methodologies. Experience in software integration and system-level test. Proficiency with standard office and documentation tools. LI-AM2 L3Harris Technologies is proud to be an Equal Opportunity Employer.
