Lead, Systems Engineer (Operations Analysis - Model and Sim) - Top Secret Clearance

L3Harris Technologies•Palm Bay, FL

23h•$127,000 - $236,500

About The Position

L3Harris Technologies is seeking a Lead Systems Engineer in Modeling, Simulation & Analysis (MS&A) to join the Mission Analysis Group (MAG). The role is based in Herndon, Virginia, or Palm Bay, Florida, and supports development of analytic toolsets for constructive simulation and experimentation across multiple domains. These capabilities support customer engagements, proposal efforts, and advanced concept exploration for internal stakeholders and external contract customers. The selected candidate will coordinate MS&A engineering efforts, integrate system performance and behaviors into operational analysis, and design and maintain simulation capabilities and analytic toolsets. The work includes developing models, simulations, and analysis products; integrating government and commercial simulations, frameworks, models, and tools; and supporting requirements development, system verification, and CONOPS development. The role also includes documenting reusable simulation capabilities, supporting technical presentations and knowledge sharing, and coaching junior technical staff. The position uses a 9/80 schedule: employees work nine days out of every 14, totaling 80 hours, with every other Friday off. Relocation assistance is available to qualified applicants. The role requires an active DoD Top Secret clearance, with the ability to obtain TS/SCI/SAP. The salary range stated for California, Connecticut, Massachusetts, New Jersey, Washington, the Greater D.C. area, Denver, and NYC is $127,000–$236,500; final compensation may vary based on experience and location. Benefits include health and disability insurance, 401(k) match, flexible spending accounts, EAP, education assistance, parental leave, paid time off, and company-paid holidays. Benefit availability may vary by hire date, schedule type, and applicable collective bargaining agreements.

Responsibilities

Communicate with internal and external stakeholders, including customers and vendors, to explain and influence policies, practices, concepts, and approaches; communicate significant matters to leadership and conduct briefings with senior leaders.
Establish short-term operational plans with measurable contributions to functional or business-area results, and make improvements to processes, systems, or products.
Coordinate MS&A engineering efforts to integrate system performance and behaviors into operational analysis.
Design multi-domain simulation capabilities using AFSIM, MATLAB, and/or STK in support of technology and mission roadmaps, internal research and development, and programs of record.
Integrate government-off-the-shelf and commercial-off-the-shelf simulations, frameworks, models, and analytic toolsets into existing software infrastructure.
Build and maintain analytic toolsets representing the find, fix, target, track, engage, and assess (F2T2EA) chain, including sensor, effects, and communications technologies and decision-support aids such as data visualization and Unity game engines.
Support operations assessment and lessons-learned development and refinement.
Document model specifications and maintain a repository of reusable simulation capabilities, frameworks, algorithms, system models, and analytic toolsets across multiple classification levels while maintaining configuration management protocols.
Support programs and pursuits by creating models, simulations, and analysis products; determine requirements, develop simulation software, troubleshoot existing capabilities, and create software designs and test plans.
Support requirements development, system verification, and concept of operations development; work with technical leaders and subject-matter experts to ensure MS&A capabilities meet operational mission requirements.
Develop new simulation capabilities and employment processes, and enhance existing analytic toolsets.
Support internal and external technical expos and roadshows by sharing knowledge of simulation capabilities and products.
Transfer knowledge through coaching and mentoring junior technical staff across the MAG.
Perform additional duties and responsibilities as assigned.
