Senior Systems Engineer - FPGA & GPU

Salary: $100,000 - 145,000 per year Requirements:

• We require a bachelors degree with at least 6 years of relevant engineering experience, a graduate degree with at least 4 years of related experience, or 10 years of comparable experience in lieu of a degree.
• We need hands-on experience with FPGA or GPU-based design, including VHDL, Verilog, CUDA, test benches, and simulation tools.
• We look for a strong grounding in RF and microwave fundamentals, including antennas, receivers, spectral behavior, and front-end architecture.
• We expect experience with signal analysis methods and tools such as pulse analysis, modulation evaluation, and emitter characterization.
• We require knowledge of radar fundamentals, including pulse radar, CW/FMCW, LPI principles, scan patterns, and threat system behavior.
• We need experience using MATLAB and Python for algorithm development, modeling, automation, data analysis, and visualization.
• We look for experience working with large IQ/sample data sets and building automated processing workflows.
• We require familiarity with test equipment such as spectrum analyzers, signal generators, oscilloscopes, vector signal analyzers, and AWGs.
• We expect experience with SDR platforms, digitizers, and receiver systems.
• We require an active Secret clearance or a recently held Top Secret/SCI clearance with the ability to maintain it.
• We need the ability to work occasional overtime or weekend hours when necessary.
• Preferred: active TS/SCI clearance.
• Preferred: experience integrating and troubleshooting complex RF or electronic warfare receiver systems.
• Preferred: experience using JIRA, Confluence, and DOORS for requirements and workflow management.
• Preferred: experience developing and implementing advanced DSP algorithms.
• Preferred: familiarity with system-level SEI, LPI/LPE techniques, or advanced emitter analysis methods.
• Preferred: experience in software integration and system-level testing.
• Preferred: proficiency with standard office and documentation tools.

• We lead FPGA and GPU architectural design, HDL coding, test bench creation, simulation, and analysis for high-performance DSP and signal-processing applications.
• We perform RF, microwave, and radar analysis, including spectrum behavior, propagation effects, receiver and front-end characteristics, pulse parameters, PRI/PW/RF measurement, modulation recognition, and emitter characterization.
• We apply DSP techniques such as FFTs, filtering, detection, estimation, and time-frequency analysis to support design and verification.
• We carry out systems engineering activities including requirements development, CONOPS definition, integration planning, test procedure creation, and performance analysis.
• We work closely with cross-functional engineering teams to plan and conduct system integration testing in laboratory and platform environments.
• We document system behavior, anomalies, and integration results in line with engineering standards, and verify and validate functionality across new and legacy baselines.
• We troubleshoot RF chains, timing and synchronization issues, calibration concerns, and hardware/software interactions during integration.
• We collaborate with customers to confirm system performance and clarify operational needs.
• We provide technical updates to management and customers and contribute to schedule, risk, and resource planning.
• We produce end-user documentation, integration reports, and technical analysis packages as needed.
• We operate effectively in a fast-paced environment with time-critical milestones and changing technical priorities.
• We uphold the highest ethical standards for ourselves and others and perform additional duties as assigned.
