• Paid Time Off (eligible after 90 days of employment)
• Sick Leave (eligible after 90 days of employment)
• Company Paid Holidays

What You'll Be Doing:
• System Design & Modeling: Designing complete industrial cooling systems, HVAC equipment, and liquid cooling loops (water/glycol) using SolidWorks.
• Standards & Compliance: Applying ASME B31 codes (e.g., B31.1, B31.3, B31.5) and industry standards to ensure piping, valving, pressure vessels, and fluid delivery systems meet regulatory and safety requirements.
• Calculations & Optimization: Performing thermal, fluid dynamics, heat transfer, and pressure drop calculations to size pumps, chillers, heat exchangers, and piping.
• Engineering Documentation: Generating detailed 3D models, fabrication drawings, Bill of Materials (BOMs), piping schematics (P&IDs), and assembly instructions.
• Cross-Functional Collaboration: Partnering with controls teams, manufacturing, and procurement to bring designs from concept to manufacturing and commissioning.
• Reporting: Reporting to Lead Mechanical Design Engineer

We are Looking for Someone Who:
• Has a Bachelor's Degree in Mechanical Engineering (BSME) or a related engineering field.
• Has 5+ years of professional experience in mechanical design engineering. • Can demonstrate a proven track record designing industrial cooling systems, HVAC systems, or liquid cooling loops (e.g., pumps, chillers, heat exchangers, manifolds). • Possesses expert-level 3D CAD design and drawing creation using SolidWorks. • Possesses active Engineer in Training (EIT) / Fundamentals of Engineering (FE) certification.
• Has strong practical understanding and working knowledge of ASME B31 piping design codes.
• Can demonstrate a strong understanding of fluid dynamics, heat transfer, and thermodynamics.
• Possesses a practical knowledge of manufacturing processes (welding, sheet metal, machining, pipe fitting).
• Demonstrates high attention to detail with excellent communication and problem solving skills.
• Is able to manage multiple project deadlines in a fast-paced environment.

Preferred:
• Experience Level: 10+ years of progressive experience in thermal systems engineering or industrial fluid processing.
