Original job description

About the Team:

The Electronic Warfare and Novel Capabilities Group (EWNC) develops and delivers advanced signal processing algorithms and prototype systems for next-generation radar and electronic warfare technologies.

EWNC fosters a culture of innovation and collaboration. We investigate cutting-edge technologies and collaborate with engineers across STR, academic researchers, and industry partners to develop practical solutions to RF sensing and counter-sensing challenges. Our engineers are empowered to pursue innovative technical ideas, engage directly with customers, lead multidisciplinary teams, and transform advanced research into prototype capabilities that address the nation's most challenging RF sensing and electronic warfare problems.

The Role:

We are looking for a Principal Engineer to develop state-of-the-art algorithms for RF sensing, sensor decision-making, and autonomous electronic warfare. Areas of interest include signal detection and classification, electronic support measures, electronic attack, electronic protection, cognitive EW, and advanced RF sensing technologies. You will lead projects and proposal efforts, lead and advise fellow researchers, scientists, and engineers on multi-disciplinary teams spread across multiple STR campuses. You will partner with customers to understand their missions and develop innovative technical approaches, proposal strategies, and program plans that address their current and future needs.

What you will do:

Lead multidisciplinary technical teams
Architect advanced RF sensing and EW algorithms from concept to operational prototype
Engage directly with customers to understand their unique requirements and national security needs, and shape our solutions to meet their objectives
Mentor junior researchers and provide technical direction across programs
Transition new technologies from research into operational prototypes
Design and apply cutting-edge signal processing to solve complex RF sensing and counter-sensing challenges
Support business development initiatives and lead proposal efforts that help shape the future technical direction of our programs and organization

Who You Are:

This position requires the ability to obtain a security clearance, for which U.S. citizenship is needed by U.S. Government
BS, MS, or PhD in Electrical Engineering, Applied Mathematics, Physics, or related technical discipline
Typically 8-12+ years of relevant experience depending on education and demonstrated expertise
Demonstrated leadership in radar, EW, RF sensing, or related defense technologies
Experience on EW or radar programs, including the development of system modes and advanced signal- and data-processing algorithms from mathematical/analytical derivation through testing and verification of system performance
Expertise in two or more of the following areas:
RF sensing and radar signal processing
Electronic warfare
Optimization
Waveform design
Adaptive signal processing
AI/ML for RF applications
Modeling & simulation
Systems engineering
Experience briefing technical work to customers, senior executives, and multidisciplinary audiences
Proficiency in one or more scientific or mathematical programming languages, such as MATLAB, Python, and C/C++
Experienced researcher and technical leader who thrives in collaborative, multidisciplinary environments
Excellent communicator and briefer, who is comfortable communicating with both technical and non-technical audiences
Strong mathematical, troubleshooting, written, and verbal communication skills

Even Better:

Active Secret or TS/SCI Clearance
Ability to apply novel, innovative and interdisciplinary approaches to challenging engineering problems

Join EWNC and help shape the future of RF sensing and electronic warfare by developing innovative technologies that transition from advanced research into operational prototype systems. While this position is ideally suited for a Principal Engineer, applicants whose qualifications closely align with the requirements are encouraged to apply. We have opportunities for talented engineers at multiple experience levels in our MA, VA, and OH offices.

Pay Information Full-Time Salary Range: $206,000 - $284,000
