What is a director modeling simulation engineer?

A Director Modeling Simulation Engineer is a senior-level leader responsible for overseeing the development and implementation of complex models and simulations, often within industries such as aerospace, defense, or engineering. This role involves managing teams of engineers and scientists, setting technical strategy, and ensuring that simulation tools meet organizational goals and project requirements. The director collaborates with other departments, ensures quality control, and often represents the modeling and simulation function to stakeholders. They are also involved in resource planning, budgeting, and mentoring junior staff. The position requires extensive technical expertise and leadership experience.

What are the key skills and qualifications needed to thrive as a director modeling simulation engineer?

To thrive as a Director Modeling Simulation Engineer, you need advanced expertise in systems engineering, computational modeling, and simulation development, typically supported by a degree in engineering or applied sciences and extensive industry experience. Familiarity with technical tools such as MATLAB, Simulink, C++, and modeling frameworks, as well as certifications like INCOSE CSEP or PMP, is common. Strong leadership, strategic thinking, and excellent communication skills help drive cross-functional teams and effectively present complex technical concepts to stakeholders. These abilities ensure successful project execution, innovation, and alignment of simulation efforts with organizational goals.

How does a director modeling simulation engineer typically collaborate with cross-functional teams to drive project success?

A Director Modeling Simulation Engineer often works closely with teams such as product development, systems engineering, and software engineering to ensure simulation models align with overall project goals. This role involves leading technical discussions, translating complex modeling requirements into actionable tasks, and providing guidance to ensure accuracy and integration of simulations within larger systems. Frequent collaboration may also include presenting findings to stakeholders, mentoring junior engineers, and coordinating with project managers to align timelines and deliverables. Strong communication and organizational skills are essential to facilitate effective teamwork and project outcomes.

What is the difference between Director Modeling Simulation Engineer vs Modeling Simulation Engineer?

AspectDirector Modeling Simulation EngineerModeling Simulation Engineer
CredentialsTypically requires a bachelor's or master's degree in engineering, computer science, or related fields; often with leadership experienceRequires a bachelor's or master's degree in engineering, computer science, or related fields
Work EnvironmentLeads teams, manages projects, and collaborates with senior managementFocuses on developing and running simulations, working within engineering teams
Industry UsageUsed in aerospace, defense, automotive, and technology sectors for high-level simulation oversightCommonly employed in similar industries for technical simulation tasks

The main difference is that the Director Modeling Simulation Engineer oversees teams and strategic projects, while the Modeling Simulation Engineer focuses on technical simulation work. The director role involves leadership, project management, and higher-level decision-making, whereas the engineer role emphasizes hands-on simulation development and analysis.

Job description

Shield AI is a venture-backed defense-tech company with the mission of protecting service members and civilians with intelligent systems. Its products include Hivemind autonomy software, V-BAT and X-BAT aircraft, and Aechelon simulation and synthetic reality technologies. With offices and facilities across the U.S., Europe, the Middle East, and Asia-Pacific, Shield AI's technology actively supports operations worldwide. For more information, visit www.shield.ai. Follow Shield AI on LinkedIn, X, Instagram, and YouTube. 

Job Description:
The Aircraft Simulation team is the nerve center of autonomy integration at Shield AI. We deploy the innovative tools, intelligent models, and streamlined processes that make it possible to evaluate complex autonomous flight algorithms at scale. Our tools are utilized in a broad range of simulation-from mission autonomy simulation to Hardware-in-the-loop, and every layer between. In an era of rapid advancement in Artificial Intelligence, our goal is simple: make AI fly-safely, reliably, and fast.
As a Staff Modeling & Simulation Engineer, you will be a pivotal force in engineering Shield AI's foundational simulation platform for our next-generation VTOL aircraft. You'll develop our emerging simulation engine and deploy advanced aircraft models in C++ across multiple engineering domains-ranging from mathematical physics to the latest in surrogate machine learning methods. You will also utilize your multiphysics and aeronautical systems knowledge to conduct system performance analysis against test and vendor data to ensure simulation results are valid in operational scenarios, and simulation platforms are both stable and fast. 
What you'll do:
  • Develop infrastructure and models in C++ for autonomous aircraft simulation.
  • Serve as a subject matter expert in modern aerospace and software engineering.
  • Architect deterministic, high-performance simulation software.
  • Lead verification and validation (V&V) analysis studies on models and model tooling.
  • Collaborate tightly across autonomy, embedded, GNC, and test engineering teams to ensure our simulation mirrors real aircraft behavior and mission scenarios.
  • Contribute to platform-agnostic simulation tooling to accelerate future development efforts.
  • Train and guide junior engineers in modeling and simulation best practices.
Required qualifications:
  • BS in Computer Science, Aerospace, Robotics, or related field.
  • 7+ years of experience in simulation software development with C++ competency; exceptional candidates with less experience and demonstrated depth will be considered.
  • Strong understanding of rigid-body dynamics, kinematics, and the physics of dynamic systems.
  • Proven experience developing or integrating simulation systems for robotics, aerospace, and/or other complex dynamic systems (e.g., maritime, space, defense ground systems, or gaming).
  • Ability to debug complex build and runtime environments.
  • Experience with simulation verification and validation.
  • Strong communication skills across software, hardware, and systems disciplines.
  • Must be eligible to obtain a Secret Clearance; Secret clearance eligibility requires US Citizenship.
Preferred qualifications:
  • MS or PhD in Computer Science, Aerospace, Robotics, or related field.
  • Familiarity with modern C++ standards (C++20 or later).
  • Grasp of real-time and deterministic software design, including multi-threading, synchronization, and memory management. 
  • Experience with DevOps-integrated simulation workflows, including CI/CD and automated testing environments.
  • Experience with Hardware- and Software-in-the-Loop simulation environments, including integration of real hardware into simulation environments.
  • Experience with CMake, package management tools (e.g. Conan, Nix), and profiling tools.
  • Experience with software testing tools (GTest, etc.)
  • Working knowledge of Python for data analysis, test automation, or simulation orchestration.
  • Experience working on autonomous aircraft systems.
  • Active Secret or Top Secret Clearance is desired.
