Sr. Engineer, M&S, CFD And Thermal Manag

CFD Simulation Engineer

You’ve discovered something special. A company that cares. Cares about leading the way in construction, engineering, manufacturing and renewable energy. Cares about redefining how energy is designed, applied and consumed. Cares about thoughtfully growing to meet market demands. And - as “one of the Healthiest 100 Workplaces in America” - is focused on the mind/body/soul of team members through our Culture of Care. We are looking for a talented CFD Simulation Engineer to join our team. The successful candidate will be responsible for using computational fluid dynamics (CFD) software to develop models and conduct analyses for research and technology (R&D) development programs and product development projects.

Key responsibilities include simulating airflow and heat transfer within enclosures housing power electronics, modeling internal components including busbars, heat sinks, fans, and electronic components as heat sources at steady state and transient operating loads, and optimizing enclosure HVAC systems for efficient cooling. Additionally, the engineer will model and simulate heat transfer and temperature distribution within battery packs, considering environmental conditions, charging/discharging cycles, and thermal management. The ideal candidate will have experience in CFD simulation, strong analytical skills, and the ability to collaborate with cross-functional teams to ensure robust and efficient designs in support of initial concepts, prototype design, and manufacturing.

Minimum requirements:

• Education: Bachelor’s degree in Mechanical engineering or related field
• Experience: 5+ years of experience in CFD analysis
• Proven experience in CFD analysis with use of Ansys Fluent/CFX, Thermal Desktop, COMSOL, Star CCM+ or similar tools
• Familiarity with CAD design software such as AutoCAD, SolidWorks, or similar
• Strong analytical and problem-solving skills to interpret simulation results and provide design recommendations
• Ability to effectively communicate technical findings and collaborate with cross-functional teams

Preferred requirements:

• Graduate degree in Mechanical Engineering or related field.
• Experience in the energy sector; with a focus on microgrid, DER products, power distribution systems and enclosures, battery energy storage systems.
• Strong understanding of related regulatory frameworks and industry standards related to the relevant energy technologies: Microgrid, Power generation, and Energy storage.
• Experience with use of CFD for thermal management system design, optimization of cooling components and temperature distribution.
• Experience leading development and optimization of thermal management systems for batteries and enclosures

Travel: 5-10%

Work Schedule: This position works between the hours of 7 AM and 5 PM, Monday- Friday. However, work may be performed at any time on any day of the week to meet business needs. Work Location: Menasha, WI

Key responsibilities:

• Simulate the airflow and heat transfer within enclosure housing power electronics (power distribution enclosures, switchboards, UPS, BESS)
• Modeling of enclosure internal components like busbars, heat sinks, fans, and individual electronic components as heat sources
• Design optimization of enclosure HVAC system for efficient cooling considering sizing, capacity, and placement and external environmental conditions
• Model and simulation of heat transfer and temperature distribution within a battery pack considering environmental conditions, charging/discharging cycles, and thermal management
• Collaborate with CAD design engineers to import existing geometries and guide design
• Collaborate with engineering to gather relevant information and requirements for boundary conditions.
