• Perform RF system analysis, including link budgets, radar performance, noise figure, dynamic range, sensitivity, and interference assessments

• Design and evaluate RF architectures involving antennas, RF front ends, transmit/receive chains, data converters, and embedded processing hardware

• Perform engineering trade studies involving performance, size, weight, power (SWaP), cost, reliability, and technical risk

• Support hardware/software/firmware integration and troubleshoot interactions across system components

• Conduct hands-on RF hardware development, prototype assembly, laboratory testing, and performance characterization using RF test instrumentation

• Develop and execute test procedures, analyze results against requirements, and identify opportunities for system improvement

• Independently manage technical assignments and occasionally lead small engineering teams or defined technical tasks

• Document designs, analyses, test results, and technical accomplishments through reports and presentations

• Participate in technical discussions with customers and support occasional field testing and demonstrations

• Contribute to technical proposals, white papers, and new research concepts as opportunities arise

Qualifications

• Bachelor’s, Master’s, or Ph.D. in Electrical Engineering, Computer Engineering, Physics, or a related field

• B.S. + 5 years, M.S. + 3 years, or Ph.D. + 0-1 year of relevant experience

• U.S. Citizenship with the ability to obtain and maintain a U.S. government security clearance

Technical Expertise

• Strong foundation in RF and microwave engineering, including RF architectures, signal chains, antennas, and transmit/receive systems

• Demonstrated experience with radar, RF communications, electronic warfare, or related sensing systems

• Experience developing system architectures and translating system-level requirements into subsystem requirements and interfaces

• Understanding of radar and communications performance analysis, including SNR, noise figure, dynamic range, propagation, and waveform considerations

• Familiarity with digital signal processing and hands-on experience with RF laboratory instrumentation

Applied Experience

• Experience developing complex RF systems from concept through integration, test, and demonstration

• Ability to troubleshoot interactions across RF hardware, digital hardware, firmware, software, and algorithms

• Familiarity with real-time processing platforms such as SDRs, FPGAs, GPUs, and SoCs

• Experience performing system-level testing, verification, and performance characterization

Additional Skills

• Proficiency in MATLAB, Python, C/C++, or similar engineering/programming environments

• Strong analytical, troubleshooting, and system-level problem-solving skills

• Ability to communicate complex technical concepts to engineering teams, program leadership, and customers

• Experience with technical documentation, design reviews, proposals, and customer presentations

• Willingness to travel occasionally for testing, demonstrations, and customer engagement

Preferred Qualifications

• Active Top Secret (TS) clearance; SCI and/or recent SAP experience preferred

• Experience with RF/EM simulation tools such as ADS, HFSS, or CST

• Experience with maritime, airborne, or other operational sensing environments

• Experience leading multidisciplinary technical efforts and mentoring junior engineers
