This role is centered on the hands-on development of operational RF communications systems, including waveforms, signal processing, SDR implementation, system integration, and performance in challenged or contested RF environments. Work across SDR, radar, resilient networking, secure communications, and RF sensing technologies while contributing directly to systems from design through integration, testing, and field demonstration.Why experienced engineers choose Secmation Spend your time building, integrating, and testing advanced RF systems. Contribute to system development from early design through field deployment. Work directly with experienced engineers, DoD customers, and mission users. Solve challenging RF, Electronic Warfare, SDR, radar, and secure communications problems. Collaborate with a small, highly technical team where every engineer has real impact. Build technology designed to transition into operational use.What you'll build and contributeContribute directly to the development of advanced RF technologies that support critical defense missions. This is a highly hands-on individual-contributor role focused on communications-system design and implementation, modeling, integration, HWIL testing, field demonstration, validation, and operational deployment. A core focus is developing and evaluating RF communications capabilities that must perform in challenged or contested environments. The position does not carry technical team-lead responsibilities.You'll work across: Electronic Warfare capabilities and applications, with opportunities to support Electronic Attack, Electronic Support, Electronic Protection, and countermeasure development. Software Defined Radiosolutions, including software, embedded processing, and integration with firmware-based radio platforms and secure embedded communications systems. Tactical RF communications, SATCOM, resilient networking, radar, and RF sensing technologies. AI-enabled RF analysis, mission systems, and adaptive signal-processing capabilities as part of the broader program environment. RF algorithm development, communications-system modeling, mission simulation, and scenario development using MATLAB, Python, or comparable tools. System integration, hardware-in-the-loop testing, field testing, validation, and live customer demonstrations. Close collaboration with RF, software, hardware, cybersecurity, and systems engineers across the program.What we're looking for U.S. citizenship and an active DoD Secret security clearance arerequired, with the ability to obtain and maintain TS/SCI.Bachelor's degree in Electrical Engineering or a related technical discipline. 8+ years of relevant experience in RF systems, communications engineering, SDR, radar, Electronic Warfare, or a related field. Demonstrated hands-on experience developing RF communications systems from design through implementation, integration, test, and operational demonstration or deployment. Experience with SDR frameworks and platforms such as GNU Radio, REDHAWK, USRP/UHD, Epiq, or comparable technologies. Experience using MATLAB, Python, or comparable tools for RF modeling, simulation, algorithm development, or data analysis. Experience with C/C++ for embedded or systems-level applications. Experience supporting system integration, HWIL testing, mission simulation, field testing, validation, or customer demonstrations. Experience with one or more of the following: tactical communications, SATCOM, resilient networking, radar, RF sensing, or Electronic Warfare systems. Deep understanding of communications-system design, including waveforms, modulation/demodulation, coding, synchronization, link performance, RF/DSP tradeoffs, waveform performance analysis, and related signal-processing techniques. Ability to independently lead analysis of communications-system behavior in challenged or contested RF environments and develop technical approaches to improve friendly-system performance, resilience, and mission effectiveness or to influence/degrade adversary RF system performance. Ability to independently execute complex technical tasks while collaborating effectively within a multidisciplinary engineering team. Strong technical communication skills, including the ability to document and present findings to internal teams, program leadership, and government stakeholders.Preferred Qualifications Experience with Electronic Attack, Electronic Support, Electronic Protection, or countermeasure development. Experience integrating software with firmware-based SDR or embedded radio platforms. Experience supporting defense or government programs through field testing or operational deployment.
