Requirements

• Bachelor’s degree in Mechanical Engineering or related engineering discipline
• 6–12+ years of experience in mechanical engineering, thermal systems design, or product development within industrial or engineered product environments
• Experience designing cooling systems for enclosed equipment — not commercial building HVAC systems
• Strong experience with thermal management for battery systems, power electronics, industrial skids, generator enclosures, modular data centers, switchgear, or similar products
• Experience sizing cooling systems based on actual equipment heat loads and operational requirements
• Strong understanding of airflow management inside enclosed systems
• Proficiency with SolidWorks or similar 3D CAD platforms
• Strong knowledge of manufacturability, fabrication methods, and industrial product integration

Nice To Haves

• Experience supporting BESS, modular data centers, power systems, or industrial energy infrastructure
• Experience with CFD analysis and thermal modeling tools
• Background in sheet metal, weldments, enclosure design, or industrial packaging
• Experience in contract manufacturing or engineered-to-order product environments
• Familiarity with UL requirements, environmental testing, or industrial compliance standards
• Experience operating in fast-paced, high-growth engineering organizations

Responsibilities

• Design and integrate cooling systems for enclosed industrial equipment including BESS systems, modular data centers, power distribution equipment, and power generation platforms
• Size cooling systems based on actual equipment heat loads, thermal rejection requirements, and operating conditions
• Develop airflow strategies inside enclosed systems including ducting, circulation paths, pressure balancing, intake/exhaust placement, and thermal zoning
• Design systems for worst-case ambient conditions, elevated operating loads, and real-world environmental constraints rather than nominal conditions only
• Select and integrate off-the-shelf cooling equipment including HVAC units, heat exchangers, fans, chillers, and thermal management components
• Own mechanical design from concept through production release including enclosure layouts, mounting systems, access requirements, structural interfaces, and equipment integration
• Develop 3D CAD models, assemblies, manufacturing drawings, and BOMs using SolidWorks and related engineering tools
• Design for manufacturability, assembly efficiency, serviceability, and long-term reliability
• Support integration of pumps, piping, cable routing, thermal barriers, and mechanical support systems
• Coordinate packaging constraints involving electrical systems, structural members, airflow, and maintenance access
• Perform thermal analysis, airflow modeling, and engineering calculations supporting cooling system performance
• Support CFD analysis and interpretation where applicable
• Validate mechanical and thermal performance through testing, prototype evaluation, and field feedback
• Participate in heat runs, system testing, troubleshooting, and performance optimization activities
• Ensure designs meet customer, regulatory, and operational requirements
• Partner with Electrical Engineering, Structural Engineering, Manufacturing Engineering, NPI, Quality, and Operations teams throughout product development lifecycle
• Collaborate closely with manufacturing teams to ensure designs align with fabrication, welding, assembly, and integration capabilities
• Support prototype builds, pilot programs, and production launch activities
• Work directly with Supply Chain and vendors on component selection, manufacturability, and technical problem solving
• Drive DFM initiatives focused on reducing complexity, improving repeatability, and supporting scalable production
• Design around manufacturing constraints including weldments, sheet metal fabrication, assembly sequencing, and production tolerances
• Resolve production issues quickly and support continuous product improvement efforts
• Standardize mechanical design approaches, cooling architectures, and reusable engineering solutions where possible
• Support Root Cause Analysis for field issues, thermal failures, or performance deviations
• Contribute to engineering standards, design guides, and best practices across product lines
• Mentor junior engineers and provide technical leadership on mechanical and thermal design challenges
• Drive continuous improvement in performance, cost, manufacturability, and reliability

Benefits

• Medical, dental, and vision insurance
• 401(k) with company match (where applicable)
• Paid Time Off (PTO) and paid holidays
• Sick time in accordance with state and local requirements
• Company-paid life insurance and disability coverage
• Career advancement opportunities within a rapidly growing organization
• Exposure to advanced manufacturing, modular infrastructure, and large-scale industrial projects
• Collaborative, fast-paced environment with strong operational and engineering leadership
• Employee-focused culture centered on safety, quality, accountability, and continuous improvement
