  • Opportunity to learn from and contribute to a premier, global engineering team!
  • Be part of leading-edge technology for the heat transfer industry.
  • Ability to impact customers across multiple industries.
  • Full health & welfare benefits, 401(k), PTO, and developmental opportunities!
  • Opportunity to travel 15% to API locations, clients and trade shows.
  • Salary Range: $95,000/year - $115,000/year

What You Will Do:

The Advanced Cooling Design Engineer will support our growing sales and design efforts by creating and managing designs for new product development projects, functioning as the dedicated CAD operator of the data center team. This position requires an individual with an expert level knowledge of SolidWorks, a high level of creativity, design for manufacturability knowledge, and excellent time management and communication skills.

  • Creation of new parts in the ERP system, manufacturing Bill Of Materials (BOM), and 3D modeling / 2D prints for production and customer approval.
  • Develop/execute the application engineering technology simulation into the heat exchanger design.
  • Work closely with both Application Engineering and Manufacturing Engineering to develop the next generation of cooling equipment.
  • Develop and manage product assemblies with integration of heat exchanger designs as required.
  • Assist the Project Engineer and Applications Engineer in detailing the standard costs of product designs.
  • Support manufacturing – fix, update and maintain BOMs, fix part info & drawings, provide drawings & answer questions as needed.
  • Author and distribute technical documents as required.
  • Support the team with validating each other’s output, analysis of results, and other efforts to produce world-class products.
  • Collaborate with internal teams to construct project scope and determine costs and manufacturing feasibility.
  • Collaborate on special projects with project team.
  • Contribute to setting project team priorities and provide technical leadership.
  • Stay updated on industry trends and advancements in heat exchanger technology.
  • Collect and share technology/application/market/competitor information.

What You Bring:

  • Bachelor of Science in Mechanical Engineering - heat transfer is specialization preferred or 10 years of proven industry experience in lieu of degree
  • Expert level knowledge and operation of SolidWorks CAD software.
  • Ability to set up & develop smart, self-generating automated 3D models and assemblies in Solidworks.
