How will you make an impact? As an R&D – Mechanical Engineering Prototype Technician, Technology Center , you will provide hands-on technical support for rapid prototyping, refrigeration system assembly, engineering builds, and test-model preparation supporting the development and evaluation of cold storage and laboratory equipment. In this role, you will work closely with R&D engineers and Technology Center technicians to fabricate, assemble, modify, instrument, and troubleshoot prototype refrigeration and mechanical systems throughout the New Product Development (NPD) process. Your primary focus will be preparing functional test models for engineering performance, verification, and reliability evaluations, including refrigeration circuit assembly, brazing, refrigerant charging, and instrumentation. Your technical skills will help engineering teams rapidly build, test, troubleshoot, and improve new products while ensuring prototype systems are prepared safely, accurately, and efficiently for engineering evaluation. What will you do? Safety, Laboratory & Equipment Management Maintain a safe work environment and demonstrate a high level of safety awareness when working with refrigeration systems, refrigerants, pressurized components, electrical equipment, and prototype products. Follow established safety procedures for brazing, refrigerant handling, pressure testing, evacuation, charging, and operation of refrigeration systems. Maintain an organized laboratory environment through 5S, Gemba walks, standard work, and good laboratory practices. Properly maintain tools, fabrication equipment, instrumentation, and refrigeration service equipment. Assist the Mechanical Prototype Lab Supervisor with inventory management, consumables, materials, and laboratory equipment readiness. Mechanical Prototyping & Refrigeration System Assembly Fabricate, assemble, modify, and troubleshoot prototype mechanical and refrigeration systems supporting cold storage and laboratory equipment development. Perform refrigeration circuit assembly, including tubing preparation, bending, fitting, brazing, leak testing, evacuation, and refrigerant charging in accordance with engineering specifications and established procedures. Install and integrate refrigeration components including compressors, condensers, evaporators, heat exchangers, expansion devices, filters, tubing, fans, and related system components. Support prototype development of conventional and cascade refrigeration systems used in temperature-controlled and ultra-low temperature (ULT) products. Perform mechanical fabrication, sheet metal modifications, component mounting, and assembly activities using engineering drawings, CAD models, and work instructions. Support prototype electrical wiring, sensor installation, and integration of motors, relays, switches, and related electromechanical components. Work closely with engineers to implement design changes and rapidly prepare updated prototype configurations for testing. Prototype Instrumentation & Test-Model Preparation Prepare and instrument prototype products, refrigeration systems, and test fixtures for engineering performance, verification, and reliability testing. Install thermocouples, temperature sensors, pressure transducers, and other measurement devices used to evaluate refrigeration and thermal system performance. Verify prototype assembly, refrigeration system operation, instrumentation readiness, and test configuration before transferring units for engineering evaluation. Assist with fabrication and installation of test fixtures, reliability test fixtures, and specialized laboratory equipment. Document prototype configurations, component changes, instrumentation locations, and build information using established laboratory information systems. Engineering Test & Troubleshooting Support . Conduct assigned product evaluation and troubleshooting activities at the system, subsystem, and component level. Apply practical knowledge of refrigeration system operation to identify potential issues involving r
