Sr. Engineer, M&S, CFD and Thermal Management

About the Company

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 development (R&D) programs and product development projects. Key responsibilities include simulating airflow and heat transfer within enclosures housing power electronics, modeling internal components such as 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.

• Simulate airflow and heat transfer within enclosure housing power electronics (power distribution enclosures, switchboards, UPS, BESS).
• Model internal enclosure 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, placement and external environmental conditions.
• Model and simulate 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.
• Propose optimized designs for future product definition and thermal management requirements within enclosure.
• Supervise and assist with product testing regimes to gather data for simulation verification and refinement.
• Define testing requirements for verification and validation of prototype builds.
• Establish partnerships and manage collaboration with HVAC suppliers and capture technology roadmaps.
• Summarize and communicate CFD results to key stakeholders.
• Define requirements for HVAC and thermal management performance from simulation to support manufacturing and site implementation.

• 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, Solid Works 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.

• 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 regulatory frameworks and industry standards related to relevant energy technologies (Microgrid, Power generation, Energy storage).
• Experience with 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.
