Senior Signatures Modeling Engineer

Leidos is looking for a Signatures Modeling Engineer to work in our Beavercreek office in the greater Dayton, OH area. The role requires applying signature modeling skills to support missions for AFRL, NASIC, LCMC, and other agencies. You will run state‑of‑the‑art signature prediction codes such as Xpatch and SENTRi, create custom tools, and perform analyses to generate highly accurate signature models.

This position requires most duties to be performed onsite due to the sensitive nature of the work, with flexible in‑office hours and the ability to perform some tasks remotely.

• Model and characterize electromagnetic (EM) phenomenology (scattering, absorption, polarization, refraction, diffraction, etc.) primarily in, but not limited to, radio frequency (RF) bands
• Characterize and evaluate radar cross sections (RCS)
• Verify and validate measured data and computational electromagnetic (CEM) predictions
• Create signature predictions using CEM prediction software (SENTRi, Xpatch, COMSOL, CST, HFSS, Feko, etc.)
• Write and present technical information related to development activities
• Assist or lead the team with business development activities, supporting proposal and technical solution development and interfacing with other parts of Leidos for multi‑disciplinary capture opportunities
• Apply technical leadership abilities and lead or assist teams to develop solutions for complex technical issues

• Bachelor’s degree with 12+ years’ experience or a master’s degree or higher with 10+ years’ experience in Electrical Engineering or a closely related scientific field such as Physics, Optics, Engineering Physics, etc.
• US citizen
• Must have an active Secret clearance with the ability to obtain a TS/SCI clearance
• Strong understanding of applied electromagnetics with skills in EM modeling and experimentation
• Adept in CEM prediction software and proven history of applying simulation tools to characterize EM phenomenology
• Excellent communication skills and a willingness and interest to collaborate in an interdisciplinary team environment to drive towards overall project and team objectives
• Expert in technical writing, documentation, and organization
• Ability to both lead and work as a team member
• Strong attention to detail and deadlines
• Ability to lead small technical teams to solve complex problems
• A self‑starter with a strong drive to lead and develop solutions that meet customer demands in a timely manner

• PhD
• Active TOP SECRET clearance desired but not required
• Radar Cross Section (RCS) design familiarity
• Knowledge of antenna and radome design principles
• CAD and meshing familiarity
• Supervisory experience
• Interest in Business Development
• Entrepreneurial interest in working across multi‑disciplinary teams on larger, more complex undertakings
• Basic understanding of, or exposure to, the following is a plus but not required:
  Automatic Target Recognition
• Radar signal processing fundamentals
• MATLAB, Python, and C++
• Experience with running simulations on high‑performance computing (HPC), graphics processor units (GPU), and other advanced processing platforms
