OVERVIEW

Full-time/Permanent Employee

Location: Dayton, OH

We are seeking a Modeling and Simulation Engineer/Scientist III to support U.S. Air Force programs in Dayton, Ohio. In this role, you will develop and integrate high‑fidelity models using the Advanced Framework for Simulation, Integration, and Modeling (AFSIM) to evaluate air and space systems, electronic warfare (EW) capabilities, and mission‑level performance. Responsibilities include creating radio‑frequency (RF) sensor and antenna models, building algorithms and simulation components, and integrating these elements into engagement‑and theater‑level AFSIM scenarios. You will work closely with Air Force stakeholders to support analysis, concept development, and acquisition decisions through physics‑based modeling, scenario development, and Monte Carlo simulation execution.

RESPONSIBILITIES

• Develop RF sensor models, algorithms, and simulation software and conduct trade-space analysis for system verification

• Develop complex antenna element and array models and integrate them into larger system simulations

• Assess and verify antenna and system-level design characteristics and performance

• Document software and hardware characteristics, simulation environment changes, test designs, and analysis results

• Integrate models into engagement-level, theater-level, and hardware-in-the-loop simulation architectures

• Integrate models and system interactions within AFSIM environments for mission-level assessments

• Conduct in-depth studies and analyses, formulate parameters, and validate modeling and simulation results

• Lead the design, specification, and development of new modeling tools and system enhancements

• Provide technical leadership and mentorship to junior engineering staff

• Exercise independent judgement in solving highly complex technical problems and provide expert recommendations

• Maintain broad knowledge of engineering disciplines, modeling techniques, and programming principles

• Work closely with Government partners and interface effectively with customers and data suppliers

• Prepare and present technical reports, proposals, briefings, and documentation

• Provide training or guidance to other employees as required

• Provide technical support to operational strategies aligned within your program and initiatives that optimize processes, enhance productivity, and ensure quality across all program functions

• Ensure 100% of planned hours are worked and recorded

• Identify and forward to your leadership any opportunities that could lead to growth within your work area

• Participate in growth efforts as requested

• Ensure all contractual deliverables are met/exceeded to the customer's satisfaction

• Complete personal PDP and attend Company meetings

• Within your program, build productive and positive professional relationships with clients

• Execute all contract requirements as assigned in accordance with the contract specific LCAT and requirements

• Perform other related duties as assigned
