About the Job

Requirements

  • U.S. citizenship is required to obtain a Top Secret security clearance.
  • A bachelor's degree in Electrical Engineering, Applied Mathematics, Physics, or a related technical discipline is required.
  • At least 5 years of experience working with RF components and subsystems, including transmit/receive modules, rotary joints, pedestals, filters, radiating structures, isolators, amplifiers, cables, and analog-to-digital/digital-to-analog converters, is required.
  • Design experience in RF systems, subsystems, and/or component analysis, including frequency planning, link budget analysis, transceiver architectures, and cascade analysis, is required.
  • Experience with RF component, subsystem, or system testing and measurement equipment and techniques, including anechoic chambers, oscilloscopes, vector network analyzers, spectrum analyzers, and signal generators, is required.
  • Proficiency in MATLAB, Python, or other higher-level programming languages is required.
  • Strong mathematical, troubleshooting, written, and verbal communication skills are required.

Responsibilities

  • Work with small, multidisciplinary teams to architect, design, implement, and test RF hardware systems for sensing, electronic warfare, and signal processing systems; systems are predominantly fielded as deployable prototypes intended to transition to low-volume product systems.
  • Collaborate with the team to quantify goals, system performance objectives, requirements, metrics, dependencies, and risks to guide the work.
  • Design, simulate, and test RF hardware systems, emphasizing RF system integration, testing, and verification.
  • Perform performance trade studies and analyses of proposed hardware architectures, using simulations and real-world testing to validate system performance.
  • Build, perform bench-top unit tests, integrate, calibrate, and demonstrate and document system performance.
  • Work with the signal processing team on sensing system test concepts and execution methods.
  • Plan and implement over-the-air system tests and demonstrations; evaluate hardware and system readiness; develop and evaluate performance metrics; verify requirements; manage system configuration and data; and write operational procedures and performance reports.
  • Review system effectiveness and identify opportunities to advance or mature subsystems and system capabilities.
  • Prepare documentation, including design specifications, drawings, test plans, and reports.

Desired Qualifications

  • Experience integrating hardware and software, software development, and/or integrating field-programmable gate arrays.
  • An active Secret or Top Secret/Sensitive Compartmented Information security clearance.
  • An advanced degree in Electrical Engineering, Applied Mathematics, Physics, or a related technical discipline.
  • Experience with RF systems engineering and technologies in sensing and electronic warfare applications, including electronic attack, electronic protection, cognitive electronic warfare, radar, or advanced electronic support measures techniques.
  • Prior design experience in antennas, RF printed circuit boards, RF integrated circuits, or transceiver building blocks such as power amplifiers, low-noise amplifiers, oscillators, mixers, or filters.

About the Company

STR

Defense, intelligence, homeland security R&D contractor

STR is an employee-owned technology firm serving national security agencies with R&D, software development, and integration under large federal contracts. Its three core areas are Analytics & C2, Cybersecurity, and Sensors, delivering AI-driven decision support, digital twins of embedded systems, and software-defined RF/acoustic hardware for multi-domain operations. Notable projects include DARPA's JAWS, AI for swarming drones, and sonar spoofing DSP, showing deep defense-domain focus. Its goal is to provide deployable technologies that enhance joint all-domain operations and situational awareness, while exploring commercial uses like automated medical imaging.
