Senior RF Engineer

Key Responsibilities 

• Lead the development of system- and subsystem-level requirements for an RF chamber supporting a Hardware-in-the-Loop (HITL) environment that includes a high-density RF array wall and full-motion simulation capabilities. 

• Architect and design the RF chamber layout, including array wall feed networks, signal distribution, shielding, isolation, and integration interfaces. 

• Oversee the complete installation of RF equipment, cabling, interconnects, and support infrastructure within the chamber, ensuring compliance with design intent, safety, and performance requirements. 

• Lead RF hardware integration efforts, including amplifiers, filters, switches, antennas, and array wall elements, into the HITL test environment. 

• Own verification and validation (V&V) planning and execution for the RF chamber and associated simulation subsystems, including performance characterization, path-loss modeling, noise analysis, and real-time target/background fidelity assessment. 

• Develop, validate, and maintain RF simulation models (using tools such as HFSS, CST, MATLAB, or equivalent) to support chamber design, array wall performance prediction, and HITL scenario generation. 

• Collaborate with systems engineers, supporting sub-system teams, and software developers to ensure seamless integration of RF components into the overall HITL architecture. 

• Conduct technical performance analysis, troubleshooting, and root-cause resolution of RF subsystems and simulation environments throughout integration and test phases. 

• Document technical specifications, design decisions, installation procedures, V&V results, and as-built configurations. 

• Interface directly with customers and internal stakeholders to support RF design reviews, requirements reviews, and technical interchange meetings. 

Required Qualifications 

• 10+ years in RF engineering, with a focus on antenna arrays, RF circuit design, or electromagnetic simulation. 

• Strong grasp of electromagnetic/antenna theory and Radars and RF Signatures. 

• Experience with Antenna Array Walls, RF Test and measurement, RF Circuit Design. 

• Familiarity with hardware-in-the-loop (HITL) testing and RF lab instrumentation (e.g., VNAs, spectrum analyzers). 

• Excellent documentation and communication skills for cross-functional collaboration. 

• Bachelor’s or Master’s degree in a relevant engineering or scientific discipline. 

• U.S. citizenship with an active TOP SECRET clearance. 

Preferred Qualifications 

• Have foundational knowledge of signal processing algorithms to support RF system analysis, test design, and performance optimization in HITL environments. 

• Familiarity with Python, MATLAB, C++, and radar cross-section modeling
