Job Description:

At L3Harris, we apply our passion to push the frontiers of advanced technology. Be part of L3Harris’ Digital Engineering transformation to accelerate development and delivery of high-payoff solutions to the warfighter!

We are seeking a dynamic Lead Modeling & Simulation (M&S) Systems Engineer to join our L3Harris team in Mason, Ohio. The Lead Modeling & Simulation Systems Engineer is responsible for supporting mission-critical maritime sensor development programs with specific focus on the analysis of next-generation surveillance, reconnaissance, and targeting sensor system performance in varied operational environments and scenarios.

When you join Lahore's Space & Sensors, you will be an integral part of an innovative and fast moving team where you will lead the collaboration with engineers and scientists to explore the feasibility and mission-level impact of advanced sensor subsystem and next-level system solutions (InfraRed Search and Track (IRST) and Imaging InfraRed). You should have a depth of InfraRed (IR), Radar, Lidar, ActiveEO, or equivalent M&S and systems engineering leadership experience in research and/or development programs. The successful leader and visionary will bring their passion for digital engineering, system architecture, modeling and simulation, analysis, and ‘what-if’ virtual explorations, and be able to adapt, communicate, and deliver on next-generation capabilities for passive, wide-area surveillance, and targeting sensor systems.

Essential Functions:

  • Understand the customer’s core mission requirement and the desired system concept of operation and the relationship to product architectures, subsystems, design, interfaces, and operations.
  • Help define technology and system roadmaps for L3Harris’ breakthrough multi-band infrared sensors, offering unprecedented range and resolution at an affordable price.
  • Evaluate the implementation of advanced sensors and weapons on target detection, tracking, identification, and engagement performance against existing and emerging threats.
  • Lead other engineers in the exploration and analysis of the feasibility and mission-level impact of complex optical sensor subsystems.
  • Apply modeling and simulation tools to translate customer or product requirements into system solutions.
  • Identify and guide system level analysis and trade studies to provide clarifying insight into the interplay between mission requirements and system performance to drive system design activities.
  • Provide technical leadership in architecting of the system model and development of lower level models of environmental conditions and objects, and/or components, subsystems, and/or system behaviors and performance, and support of the integration and use of these models across the engineering team.
  • Support development of scenario scripts and data sets to design and execute simulations; perform data acquisition and analysis of scenario results; develop and convey conclusions and recommendations in a way meaningful to the design engineers.
  • ‘One Team’ collaboration with internal subsystem teams and multiple external suppliers, teammates, platform providers, and customer organizations in execution of all program activities.


  • DoD active secret clearance.
  • Bachelor’s degree in Electrical Engineering, Computer Engineering, Computer Science, Physics, or a related field and minimum 9 years of prior relevant experience. Graduate Degree and a minimum of 7 years of prior related experience.
  • Minimum of 9 years of applicable modeling and simulation, operations research, systems analysis and trade studies, and/or systems engineering experience.
  • Demonstrated hands-on experience in sensor system performance modeling and/or simulation, with a track record of influencing and optimizing system design through M&S activities.
  • Experience with System Engineering functions such as:
    • System Trade Studies or System Performance Modeling;
    • System Conceptual Design & Analysis;
    • Experience with deep technical analysis;
  • Experience developing/creating custom analysis tools (MATLAB, Mathcad, Python, etc.).
  • Able to work collaboratively with the technical team.
  • Able to use excellent communication skills to work with individuals across L3Harris locations and the customer community to obtain consensus and understanding of the solution with minimal oversight.
  • Ability to develop creative yet practical solutions to technical challenges; able to recognize opportunities rather than see limitations or issues.
  • Background in InfraRed (IR) sensor modeling or equivalent (Radar, Lidar, ActiveEO, etc.).
  • Strong drive and sense of ownership.
  • Willing to travel as required.

Preferred Skills:

  • Working knowledge of standard models such as NV-IPM, SPIRITS, MuSES, ShipIR, and DIRSIG.
  • Ability to use creativity to advocate and logically drive practical technical solutions.
  • Familiarity with optimizing system design through M&S activities.
  • Demonstrated knowledge of a scripting language (e.g., JavaScript, MATLAB, Python).
  • Excellent verbal and written communication skills.
  • Proposal development experience.
