Requirements:
We require a bachelors degree with at least 6 years of relevant engineering experience, a masters degree with at least 4 years of related engineering experience, or 10 years of equivalent experience in lieu of a degree. We need a strong understanding of RF and microwave fundamentals, including antennas, receivers, spectral characteristics, and front-end design. We expect demonstrated experience with signal analysis methods and tools such as pulse analysis, modulation assessment, and emitter characterization. We require knowledge of radar fundamentals, including pulse radar, CW/FMCW, LPI concepts, scan patterns, and threat-system behavior. We need proficiency in digital signal processing, with strong MATLAB skills for algorithm development, modeling, simulation, and data analysis. We expect solid command of DSP principles such as filtering, spectral analysis, FFTs, modulation, sampling theory, and noise reduction. We require the ability to support algorithm implementation in C, C++, or Python. We require an active Secret clearance or recent TS/SCI clearance with the ability to maintain it. We require the ability to travel up to 10%. Preferred qualifications include active TS/SCI clearance, experience with RF or electronic warfare receiver integration and troubleshooting, and familiarity with JIRA, Confluence, and DOORS. Preferred experience includes using MATLAB and Python for algorithm development, automation, data analysis, and visualization. Preferred background includes working with large IQ/sample datasets, advanced DSP algorithm development, software integration, and system-level testing.
Responsibilities:
We partner closely with customers to design and implement new system capabilities. We write requirements, support development, and perform integration testing of new or updated products in laboratory, airborne, and ground-based environments. We verify and validate new baseline functionality while ensuring legacy behavior remains intact. We collaborate with systems engineering, agile development, flight line test, product development, and project engineering teams to understand new baseline capabilities. We work with our internal research and development teams to advance proprietary ELINT technologies and capabilities. We document test status and anomalies, and we verify corrective actions for hardware and software issues. We coordinate with customers to ensure satisfaction with system performance. We work with management to build and follow schedules and budgets for assigned efforts. We provide regular progress updates to management and customers. We operate effectively in a fast-paced, time-sensitive environment. We communicate across functions to support program execution from development through integration and delivery. We analyze customer needs, including system and subsystem trade studies, and develop detailed hardware and software specifications. We create test plans and procedures for equipment such as anechoic chambers, spectrum analyzers, and network analyzers. We contribute across the full program and engineering lifecycle, including IRAD, technical baseline development, and requirements management. We apply strong problem-solving skills with careful documentation, verification, and validation practices. We prepare working contract proposals and take on other duties as assigned.
