Senior Modeling and Simulation Engineer

About the role

Core4ce is seeking a Senior Modeling and Simulation (M&S) Engineer to support the Integrated Healthcare Transformation (IHT) initiative within the Veterans Health Administration (VHA). This role is responsible for the design, development, and execution of complex, multi-system simulations that model healthcare workflows, system architectures, and technical infrastructures. The Senior Engineer will work closely with stakeholders to define simulation goals, identify critical variables, and produce data-driven insights that inform technical decisions and optimize healthcare delivery systems.

Responsibilities

• Lead the coordination with government customers and stakeholders to identify model requirements, simulation objectives, and key performance variables.
• Design, develop, and execute complex, multi-system simulations to evaluate the performance, reliability, and scalability of healthcare technology solutions.
• Construct custom simulations tailored to specific customer specifications and operational scenarios.
• Perform software modeling and device characterization to ensure accurate representation of system components within simulated environments.
• Develop both "hard" (hardware-in-the-loop) and "soft" (purely software/mathematical) models to support diverse testing requirements.
• Conduct parametric testing and implement measurement automation to increase the efficiency and accuracy of simulation cycles.
• Analyze simulation data to identify system bottlenecks, vulnerabilities, and potential areas for optimization.
• Document and report on test results, providing clear, actionable insights to technical users and program management.
• Establish simulation frameworks that support the validation of interoperability and data exchange standards across disparate healthcare systems.
• Provide technical expertise in the selection of M&S tools, languages, and methodologies appropriate for large-scale enterprise transformation.
• Collaborate with system architects and engineers to integrate modeling and simulation into the broader engineering and software development lifecycles.
• Manage the lifecycle of simulation assets, ensuring models are maintained, version-controlled, and updated as system requirements evolve.

Required Qualifications

• Must be able to obtain and maintain a Public Trust clearance for this role.
• Bachelor's degree in Engineering, Computer Science, Mathematics, Physics, or a related technical field.
• Minimum of 10 years of professional experience in modeling and simulation engineering.
• Experience supporting the Veterans Health Administration (VHA), Department of Veterans Affairs (VA), or Department of Defense (DoD) in a modeling and simulation capacity.
• Extensive experience in model design and execution, specifically involving complex, multi-system environments.
• Proven track record of developing software modeling, device characterization, and hard/soft modeling solutions.
• Strong experience in parametric testing and the implementation of measurement automation scripts/tools.
• Demonstrated ability to coordinate directly with customers to translate business needs into technical simulation requirements and goals.
• Proficiency in simulation languages and tools (e.g., MATLAB/Simulink, AnyLogic, Arena, OPNET, or similar enterprise-grade M&S software).
• Strong technical writing skills with experience documenting test plans, simulation architectures, and final analytical reports.
• Excellent problem-solving skills and the ability to visualize complex system interactions.

Preferred Qualifications

• Experience modeling clinical workflows, patient flow, or healthcare information technology (HIT) infrastructures.
• Knowledge of healthcare data standards (HL7, FHIR) and their application within simulated data exchanges.
• Experience working within an Agile or SAFe environment, providing simulation support for incremental feature development.
• Familiarity with cloud-based simulation environments and high-performance computing (HPC) resources.

Benefits

• 401(k) with 100% company match on the first 6% deferred, with immediate vesting
• Comprehensive medical, dental, and vision coverage—employee portion paid 100% by Core4ce
• Unlimited access to training and certifications, with no pre-set cap on eligible professional development
• Tuition assistance for job-related degrees and courses
• Paid parental leave, PTO that grows with tenure, and generous holiday schedules
• Core4ce's "The Forge" program gives every employee the chance to propose bold innovations and help bring them to life with internal backing
