What are the key skills and qualifications needed to thrive in the Modeling Simulation Engineer position, and why are they important?

To thrive as a Modeling Simulation Engineer, you need a strong background in mathematics, physics, and computer science, typically supported by a relevant engineering or science degree. Proficiency with simulation software such as MATLAB, Simulink, ANSYS, or similar tools, and sometimes certifications in systems engineering or modeling methodologies, are commonly required. Strong analytical thinking, problem-solving abilities, and effective communication skills set top candidates apart. These qualifications are crucial for accurately representing complex systems, translating requirements into effective models, and collaborating with multidisciplinary teams to achieve project goals.

What does a Modeling Simulation Engineer do?

A Modeling Simulation Engineer develops virtual models and simulations to analyze complex systems and processes. They use mathematical models, computer simulations, and data analysis to predict system performance and optimize designs before physical implementation. These engineers typically work in industries like aerospace, defense, automotive, and healthcare to improve efficiency, safety, and decision-making. Their role often involves coding, algorithm development, and working with simulation software to test real-world scenarios in a virtual environment.

What are the typical responsibilities and project stages for a Modeling Simulation Engineer?

Modeling Simulation Engineers are responsible for developing mathematical models, running simulations, analyzing results, and providing recommendations to improve system performance or design. Projects often begin with understanding client or stakeholder requirements, followed by designing models based on those needs and iteratively refining them as data is collected. Engineers work closely with design, hardware, and software teams to validate models and ensure alignment with real-world performance. Collaborating with colleagues and presenting findings to both technical and non-technical audiences are routine aspects of the job, making cross-functional communication vital for project success.

Job description

Lockheed Martin is a global security and aerospace company that employs approximately 114,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration, and sustainment of advanced technology systems, products, and services.
At Lockheed Martin, we apply our passion for purposeful innovation to keep people safe and solve the world's most complex challenges.
We are seeking an experienced Guidance, Navigation, and Control (GNC) Engineer who will specialize in Modeling and Simulation (M&S) of complex technical solutions to join our team in sunny Orlando Florida!
What You Will Be Doing
This person will join a highly skilled team of systems engineering technologists and algorithm developers supporting various contracts and IRADs within Missiles and Fire Control. Modeling & Simulation Engineer tasks include:
Design and documentation of model and simulation requirements and architecture
Develop, verify, and validate both complex models and simulations such as missile 6-degree-of-freedom simulations (6-DOF) and effects-based simulations
Evaluate system performance in complex scenarios and environments and verify system and subsystem level requirements
Perform critical studies, analyses, and test activities
Support ground and flight test efforts including Hardware-In-The-Loop (HWIL) activities
Support program reviews and technical interchange meetings with internal leadership and/or external customers.
The candidate must have experience in weapon system and/or sensor modeling, both for the items to be modeled, and the synthetic modeled environments used to stimulate the simulated hardware.
The M&S Engineer must be able to work with subsystem and software engineers to integrate MATLAB models, C++ models, and actual tactical software into the simulations.
The M&S Engineer must be proficient in C++ and MATLAB. The candidate must have good communication skills and must be comfortable working in a collaborative environment.
