This is an opportunity to join a team that builds custom‑engineered heat transfer, refrigeration, and air‑handling systems used in a variety of environments - with strong organizational investment in innovation, new product development, and market expansion.

Relocation assistance is available for this position.

Due to confidentiality of some of these products, must be a US Citizen.

Key Responsibilities

• Creating and refining mechanical designs for heat exchangers, air‑conditioning systems, refrigeration equipment, and air‑handling units using 2D and 3D CAD tools (e.g., Creo, AutoCAD).
• Performing component sizing, selection, and system performance analysis.
• Provide budget, cost, and schedule input in order to drive new product development projects.
• Perform hands-on support of prototype fabrication, assembly, and product testing.
• Reviewing customer requirements and developing compliant, high‑quality product designs.
• Coordinating with suppliers and evaluating components, subsystems, and services.
• Supporting prototype builds, testing, qualification activities, and production release.
• Assisting with cost estimates, schedules, and proposal inputs.
• Providing hands‑on engineering support to cross‑functional teams, including manufacturing and testing.

Qualifications

• Bachelor's degree in Mechanical Engineering and 2-10 years of relevant experience (depending on level of position).
• Experience designing mechanical components or equipment - ideally in HVAC&R, thermal systems, or related mechanical assemblies (sheet metal, welded structures, machined parts).
• Proficiency with CAD modeling and drafting; familiarity with ASME drawing standards.
• Strong documentation, analytical, and communication skills.
• Comfortable working independently while collaborating with a multidisciplinary team.
• Proficiency with Microsoft Office tools.

Additional Desired Qualifications

• Experience using PTC Creo (including sheet metal and assemblies).
• Experience with Windchill or similar PDM/PLM platforms.
