Company

Develops engines, generators, power conversion and UPS systems, EV components, electrification solutions, microgrid controls, and clean energy products for OEM, residential, industrial, and commercial customers.

What you will do

• Lead thermal and fluid-flow simulations to evaluate and optimize cooling-system performance using CFD tools, including Siemens STAR-CCM+ and comparable technologies.
• Analyze engine thermal-management systems, including radiators, fans, airflow distribution, cooling packages, and related components.
• Perform simulation and validation for fuel delivery, exhaust, thermal-management, and power-electronics cooling systems.
• Develop analytical methods, processes, and optimization tools that improve thermal performance, robustness, and cost effectiveness.
• Conduct experimental testing and data analysis to correlate simulation models with physical validation results.
• Collaborate with product-development engineers, laboratory teams, suppliers, and cross-functional stakeholders; publish technical reports, standards, procedures, guidelines, and documentation.

Requirements

• Bachelor’s degree in mechanical engineering or a related engineering discipline.
• At least six years of engineering experience in thermal systems, fluid dynamics, simulation, validation, or related technical disciplines. Graduate-level research may count toward the experience requirement.
• Demonstrated experience applying Computational Fluid Dynamics tools to solve complex engineering problems.
• Strong understanding of heat transfer, thermodynamics, fluid flow, thermal management, cooling systems, and related engineering principles.
• Experience developing simulation models and validating analytical predictions through testing and experimentation.
• Effective technical communication skills, including presenting findings and recommendations to technical and non-technical audiences.

Nice to have

• Master’s degree or PhD in Mechanical Engineering, Thermal Sciences, Fluid Dynamics, Heat Transfer, or a related field.
• Experience with Siemens STAR-CCM+ or similar CFD software.
• Experience supporting engine cooling systems, power-generation equipment, power-electronics cooling, heat exchangers, or thermal-management systems.
• Experience correlating simulation models with laboratory and field validation data.
• Experience authoring technical papers, engineering standards, best practices, or white papers.

Culture & Benefits
