This role focuses on creating and validating mathematical models and multi-body dynamic simulations using MATLAB, Simulink, and Simscape to analyze the performance of thermal fluid systems, pneumatic actuators, and electro-mechanical mechanisms. The engineer will collaborate with cross-functional teams, guide global modeling initiatives, and provide technical leadership to advance model-based engineering practices. Key Responsibilities:
Develop multi-domain physics-based plant models and multi-body dynamic simulations for aerospace systems, including actuators, thermal fluid systems, and dynamic mechanical systems. Validate models using experimental lab data, application testing, and hardware-in-the-loop (HIL) setups. Support controls integration with system-level simulations for closed-loop performance verification and stability analysis. Analyze actuator-structure interactions, load transmission, and transient responses using multi-domain coupling techniques. Refine and update models based on experimental results to improve predictive accuracy and reliability. Collaborate with global teams and product teams to define modeling objectives, assumptions, and expected results while ensuring the technical quality of model deliverables. Document analysis processes and produce traceable verification artifacts, including interface control documents and verification matrices. Mentor junior engineers, support global modeling efforts, and champion best practices for modeling and simulation workflows. Required Skills:
Minimum of six (6) years of relevant professional experience, including hands-on work in modeling mechanical, thermal fluid, pneumatic, and actuator systems. Expertise in MATLAB, Simulink, and Simscape (including Simscape Fluids) for modeling mechanical, thermal fluid, pneumatic, and actuator systems. Proficiency in modeling and simulation tools for dynamic systems and thermal-fluid systems. Experience with hardware-in-the-loop testbeds, real-time model deployment, and system testing. Ability to implement systems engineering principles for simulation activities, including multidisciplinary system coupling and actuator integration. Strong technical data analysis, model refinement, and verification skills using experimental and flight test data. Excellent cross-functional communication and teamwork abilities, including mentoring, technical oversight, and delivering traceable verification artifacts. Familiarity with aerospace and defense standards (e.g., MIL-STD-810/DO-254). US Citizenship with the ability to obtain and maintain a secret clearance. Desired Skills :
Ten (10) years or more of relevant professional experience, including hands-on work in modeling mechanical, thermal fluid, pneumatic, and actuator systems. Knowledge of Simulation Process Data Management (SPDM) tools. Experience with advanced modeling software such as Siemens Amesim. Hands-on experience with multi-body dynamics and actuator-structure interaction assessments. Exposure to CAD/FEA workflows, thermal-stress analyses, and experimental testing. Education Requirements :
Bachelor's degree in mechanical or aerospace engineering, or a related discipline from an accredited institution. Advanced degree (MS or PhD) in mechanical or aerospace engineering, or a related discipline strongly preferred but not required. Benefits include the following:
Healthcare coverage Retirement plan Life insurance, AD&D, and disability benefits Wellness programs Paid time off, including holidays Learning and Development resources Employee assistance resources Pay and benefits are subject to change at any time and may be modified at the discretion of the company, consistent with the terms of any applicable compensation or benefit plans.
