RF Engineer – Radio Systems / RF Hardware

Overview

CIS Secure is seeking an RF Engineer – Radio Systems / RF Hardware to join our team supporting the REACT program at Aberdeen Proving Ground (APG), Maryland.

The RF Engineer will lead the design, development, and integration of custom radio and RF hardware supporting critical national security missions. This role works across RF, digital, FPGA, and embedded systems to develop new communications capabilities, troubleshoot complex hardware, and rapidly prototype solutions for advanced mission requirements.

• Provide hands-on engineering expertise across the full radio development lifecycle, from architecture and component selection through circuit design, FPGA integration, board bring-up, and RF characterization.
• Develop and integrate RF front ends, digital processing hardware, and embedded components.
• Use laboratory test equipment to evaluate and troubleshoot system performance.
• Collaborate with embedded software, FPGA, cybersecurity, and systems engineering personnel to develop and mature custom radio capabilities for sophisticated operational environments.
• Perform other duties as assigned.

Required skills

• Experience designing, developing, integrating, or troubleshooting RF communication systems or radio hardware.
• Strong understanding of RF fundamentals, including signal chains, filtering, amplification, frequency conversion, impedance matching, noise, and link budgets.
• Experience with analog/digital circuit design and PCB-level hardware development.
• Familiarity with MATLAB/Simulink, Python, C/C++, or embedded Linux.
• Experience developing or integrating FPGA-based systems using Verilog, SystemVerilog, or VHDL.
• Experience integrating embedded processors, FPGAs, RF transceivers, ADCs/DACs, or similar devices.
• Hands-on experience with RF and electronics test equipment such as oscilloscopes, spectrum analyzers, VNAs, signal generators, and logic analyzers.
• Ability to troubleshoot hardware at the component, board, and system levels.

Education

• Bachelor's degree in Electrical Engineering, Computer Engineering, or a related technical discipline, or equivalent relevant experience.

Clearance

• Active TS/SCI security clearance required.

Operating hours and expectations

• This position anticipates standard operating hours, with flexibility as required to support program and mission requirements.
• This position is based at Aberdeen Proving Ground (APG), Maryland.

Travel

• No regular travel is anticipated for this position.

• Experience designing a radio or RF transceiver from the board/component level, not solely integrating commercial radios.
• Experience with software-defined radios, RF transceiver ICs, RF front ends, PLLs, mixers, LNAs, PAs, and filters.
• Experience implementing DSP functions in FPGA logic, including filtering, FFTs, modulation/demodulation, or digital up/down conversion.
• Experience with RF/mixed-signal PCB design, controlled impedance, grounding, shielding, signal integrity, and EMI/EMC considerations.
• Experience with RFSoC, SoC FPGA, high-speed ADC/DAC interfaces, or similar architectures.
• Experience with communications, unmanned systems, electronic warfare, SIGINT, radar, or other RF-intensive defense applications.
• Experience rapidly prototyping and debugging custom RF or embedded hardware.
