Senior RF Engineer

STR•Woburn, MA

About The Position

The Senior RF Engineer will support design, development, integration, and testing activities in a research and development environment within STR’s Space Missions and Sensing Sector. The role contributes to teams developing counter-sensing systems for radar, electronic warfare, and other applications. Systems are primarily deployable prototypes intended to transition to low-volume product systems. The position offers opportunities for growth in a fast-paced, expanding company. The engineer works with small multidisciplinary teams to architect, design, implement, and test RF hardware systems that enable sensing, electronic warfare, and signal-processing systems. Work includes RF system integration, test, and verification; hardware architecture analysis; performance trade studies; simulation and real-world testing; and system demonstrations. The role also involves collaboration with signal-processing teams, evaluation of system readiness and performance, configuration and data management, operational documentation, and identification of opportunities to mature system capabilities.

Requirements

Bachelor’s degree in Electrical Engineering, Applied Mathematics, Physics, or a related technical discipline.
At least 5 years of experience working with RF components and subsystems, including T/R modules, rotary joints, pedestals, filters, radiating structures, isolators, amplifiers, cables, and ADC/DAC.
Design experience in RF systems, subsystems, and/or component analysis, including frequency planning, link budget analysis, transceiver architectures, and cascade analysis.
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.
Proficiency in MATLAB, Python, and/or other higher-level languages.
Strong mathematical, troubleshooting, written, and verbal communication skills.
Ability to obtain a Top Secret security clearance; U.S. citizenship is required by the U.S. Government.

Nice To Haves

Active Secret or TS/SCI clearance.
Advanced degree in Electrical Engineering, Applied Mathematics, Physics, or a related technical discipline.
Experience integrating hardware and software, software development, and/or integrating FPGAs.
Experience with RF systems engineering and technologies in sensing and electronic warfare applications, including electronic attack, electronic protection, cognitive EW, radar, and advanced ESM techniques.
Design experience in one or more of the following: antennas, RF printed circuit boards, RF integrated circuits, or transceiver building blocks such as power amplifiers, low-noise amplifiers, oscillators, mixers, and filters.

Responsibilities

Work with small multidisciplinary teams to architect, design, implement, and test RF hardware systems.
Collaborate with the team to define goals, system performance objectives, requirements, metrics, dependencies, and risks.
Design, simulate, and test RF hardware systems, emphasizing RF system integration, test, and verification.
Perform performance trade studies and analyses of proposed hardware architectures.
Analyze performance through simulations and real-world testing to validate system performance.
Build systems; perform bench-top unit testing; integrate and calibrate hardware; 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 design specifications, drawings, test plans, and reports.
