About The Position

Integer Technologies is hiring a Senior Modeling and Simulation Engineer for its Digital Engineering Division. Reporting to the Industry 4.0 Engineering Manager, this role develops models and simulation tools for safe, high-performance battery systems. The engineer works across electrochemistry, thermal behavior, digital engineering, and machine learning to advance battery technologies from research into defensible system designs for the DoD.

The role develops high-fidelity electrochemical and thermal models to predict battery performance, cycle-life degradation, and safety under abuse conditions; connects physics-based modeling with Model-Based Systems Engineering (MBSE) workflows; and uses AI/ML to create surrogate and reduced-order models linking component-level behavior to system-level performance. The engineer also collaborates across teams to integrate battery models into system architectures for defense and advanced commercial applications.

Requirements

• U.S. citizenship and ability to obtain and maintain a U.S. DoD Secret clearance.
• Bachelor’s degree in Chemical Engineering, Materials Science, Physics, Electrical Engineering, or a related field.
• At least 5 years of professional experience in scientific modeling, simulation, or digital engineering.
• Experience developing and validating physics-based or multiphysics models using COMSOL, MATLAB/Simulink, Simscape, Simcenter, ANSYS, or comparable platforms.
• Strong Python programming skills for automation and data analysis.
• Experience with AI/ML frameworks such as TensorFlow, PyTorch, or scikit-learn.
• Strong problem-solving skills and attention to detail.
• Ability to provide concise briefings to stakeholders.

Nice To Haves

• Eligibility for a Top Secret clearance.
• Master’s or PhD in a relevant engineering or scientific discipline.
• Experience in battery systems, electrochemistry, energy storage, reactive transport, thermal sciences, or another relevant physical domain.
• Strong modeling fundamentals and interest in developing battery expertise.
• Experience with Hardware-in-the-Loop (HIL) simulation and FPGAs.
• Experience designing pack-level thermal management integration, including ePCM and cooling plates, as well as potting/encapsulation and structural adhesives.
• Experience developing and maintaining enterprise software in production.

Responsibilities

• Develop and validate multiphysics models of battery electrochemistry, thermal runaway, and cell-to-cell propagation to assess survivability and abuse tolerance.
• Develop and manage system models using MBSE methodologies, including SysML v1/v2, to define requirements, architecture, and interfaces.
• Build and train surrogate and reduced-order models using Python frameworks such as PyTorch and scikit-learn to accelerate simulations and connect digital engineering with operational data.
• Support Battery Management System development by modeling and validating State of Charge (SOC) and State of Health (SOH) estimation algorithms.
• Work with test engineering to use battery testing cycler data for ongoing model calibration and validation.
• Present simulation results, architectural solutions, and risk assessments to technical teams and non-technical stakeholders.
• Integrate battery models into larger system architectures for defense and advanced commercial applications.
