RF/Radar Engineer — Principal/Senior Principal

RF/Radar Engineer - Principal/Senior Principal

Phased n Research is seeking a Principal or Senior RF/Radar Engineer to support U.S. Army radar Modeling and Simulation (M&S) programs. You will serve as the radar domain expert on a team of M&S software engineers, providing the systems engineering depth, performance analysis, and technical credibility needed to ensure simulation tools accurately represent real-world radar behavior. This role is less about writing simulation code and more about knowing what the simulation needs to get right, and why.

Primary Customer:

• This effort directly supports the Program Manager Search, Track, Acquire, Radiate, and Eliminate (PM STARE).

Radar Systems & Performance Analysis:

• Define and assess radar system performance across operationally representative scenarios including detection, tracking, discrimination, waveform behavior, and electronic protection.
• Develop radar performance analyses and trade studies to inform Army program requirements and architecture decisions.
• Evaluate M&S outputs against analytical predictions and empirical data; identify simulation fidelity gaps and communicate findings clearly to the software development team.
• Develop and validate radar signal processing algorithms and waveform designs, providing the software team with well-defined, implementable specifications.
• Assess radar performance in challenging environments including dense clutter, ECM, and multi-target engagements.

M&S Support & Validation:

• Provide radar domain expertise to support the development, validation, and accreditation of radar M&S tools for U.S. Army customers.
• Author and review model specifications, simulation validation plans, and V&V documentation grounded in radar physics and systems engineering principles.
• Use MATLAB and Python to prototype radar algorithms, verify signal processing behavior, and produce reference outputs for software team validation.
• Support integration and performance testing of simulation systems by defining acceptance criteria and reviewing test results from a radar systems perspective.

Program & Customer Support:

• Serve as the senior radar technical resource in supporting leadership with engagements with U.S. Army customers, supporting TIMs, design reviews, and program milestones.
• Translate customer requirements into clear radar system specifications and M&S development tasks for the engineering team.
• Produce technical documentation, requirements artifacts, and briefings that demonstrate program progress and support government reviews.
• Mentor junior engineers on radar systems fundamentals and M&S methodology.

Required Qualifications:

• Bachelor's degree in Electrical Engineering, Physics, Mathematics, or closely related STEM field.
• 10+ years of directly relevant radar or RF systems experience.
• Active Secret clearance; eligibility and willingness to pursue Top Secret/SCI.
• Demonstrated experience in radar system design, performance analysis, or algorithm and waveform development.
• Proficiency in MATLAB and/or Python for radar signal processing, simulation, or algorithm prototyping.
• Strong written and verbal communication skills; proven ability to present technical radar concepts to both engineering teams and government customers.
• Ability to work independently, drive technical tasks to completion, and operate effectively in fast-paced, mission-driven programs.

Preferred Qualifications:

• Master's degree or PhD in Electrical Engineering, Applied Physics, Mathematics or related STEM field.
• Direct relevant radar or RF systems experience.
• Experience with C++/CUDA software optimization and high performance computing.
• Active TS/SCI clearance.
• Prior experience supporting U.S. Army radar programs or other DoD M&S efforts.
• Background in missile defense, air defense, or ground-based radar systems.
• Working knowledge of C++ in a radar or signal processing context.

• Familiarity with software development workflows including version control, CMake, or containerization tools such as Docker or Podman.
