• Perform RF, microwave, and radar‑related analysis including spectrum behavior, propagation effects, receiver/front‑end characteristics, pulse parameters, PRI/PW/RF measurement, modulation recognition, and emitter characterization.
• Apply DSP techniques including FFTs, filtering, detection, estimation, and time‑frequency analysis to support system design and verification.
• Execute systems engineering tasks including requirements development (JIRA/DOORS), CONOPS definition, integration planning, test procedures, and performance analysis.
• Work closely with cross‑functional engineering teams to plan and conduct system integration testing in laboratory and platform environments.
• Document system behavior, anomalies, and integration results following established engineering standards; verify and validate system functionality across new and legacy baselines.
• Support troubleshooting of RF chains, timing/synchronization issues, calibration, and hardware/software interaction during system integration.
• Collaborate with customers to ensure satisfaction with system performance and to clarify operational requirements.
• Provide technical updates to management and customers, contributing to schedule, risk, and resource planning.
• Produce end‑user documentation, integration reports, and technical analysis packages as required.
• Work effectively in a fast‑paced environment with time‑critical program milestones and evolving technical objectives.
• Active Secret or recently held Top Secret/SCI security clearance with the ability to maintain.
• Ability to work occasional overtime or weekend hours if required.

Qualifications

• Bachelor’s Degree and minimum 6 years of prior relevant engineering experience.
• Graduate Degree and a minimum of 4 years of prior related engineering experience.
• In lieu of a degree, a minimum of 10 years of prior related engineering experience.
• Demonstrated experience with FPGA or GPU‑based design, including VHDL/Verilog/CUDA, test benches, and simulation tools.
