Job summary

SIXGEN is seeking a Lead Modeling and Simulation Engineer to onsite at Fort Meade, MD. You will lead cyber-physical and virtual simulation environments, guiding test ranges and emulated networks to reflect real-world threats and mission requirements.

The role requires 10+ years in modeling, simulation, or systems engineering, and an active TS/SCI clearance. Travel up to 10% may be involved, with comprehensive DoD-compliant processes and strong collaboration across teams.

Qualifications

• Bachelor's or Master's degree in Computer Science, Engineering, Mathematics, or a related technical field.
• 10+ years of experience in modeling and simulation, cyber range development, or systems engineering.
• Experience with simulation tools such as MATLAB, Simulink, STK, ns-3, and OMNeT++.
• Experience supporting cyber operations, testing and training environments.
• Strong knowledge of network architectures, operating systems, and cyber threat behaviors.
• Active TS/SCI clearance (or ability to obtain/maintain).
• Experience with cyber range platforms and adversary emulation tools.
• Familiarity with MITRE ATT&CK, cyber kill chain analysis, and threat modeling.
• Knowledge of cloud-based simulation environments and containerized architectures.
• DevSecOps pipelines supporting simulation and testing environments.

Responsibilities

• Lead the development and implementation of cyber-physical and virtual simulation environments, including test ranges and emulated networks.
• Design and execute modeling frameworks to replicate real-world systems, threats, and operational scenarios.
• Integrate live, virtual, and constructive (LVC) simulation capabilities to support training, testing, and mission rehearsal.
• Collaborate with cyber operators, engineers, and analysts to ensure simulations accurately reflect threat behaviors and mission requirements.
• Oversee the validation and verification (V&V) of models and simulation outputs to ensure accuracy and reliability.
• Support data collection, analysis, and visualization from simulation activities to inform decision-making.
• Ensure compliance with DoD/IC modeling and simulation standards, cybersecurity requirements, and system accreditation processes.
