Nice To Haves

• Understanding of designing parts and assemblies for high volume production.
• Understanding of machining, sheet metal, welding, bending/forming, and related manufacturing methods.
• Understanding of fluid dynamics principles, especially as they relate to heat transfer and fluid flow in cooling systems.
• Process piping, P&ID and building mechanical design, particularly with respect to HVAC and fluid transfer.
• Understanding of pump, motor, heat exchanger, and sensor selection, testing, and validation.
• Rapid prototyping manufacturing techniques and testing of thermal/mechanical components; familiarity with lab equipment for data collection.
• Reliability analysis, tolerance stack-up calculations, or statistical design tools like design for lean six sigma would be an asset.

Responsibilities

• Contribute to the design of Coolant Distribution Units (CDUs) through the NPi process; concept development, prototyping, DVT, UL Certification, and PVT to product launch and mass production.
• Support rapid iteration of design concepts through technology assessment, feasibility analysis, and proofs of concept, oversee the building and testing of thermal, hydraulic, and integrated assembly prototypes for validation.
• Work closely with core teams, customers, and industry partners to ensure our CDU designs are delivered on time, meeting and exceeding market needs.
• Detailed product design using principles of thermodynamics, fluid mechanics, and mechanical engineering with a focus on delivering high performance and high reliability products.
• Create detailed engineering drawings, reports, design reviews, and other documentation to clearly explain convey design ideas, test results, and recommendations to internal teams and external stakeholders.
• Develop CDU component and assembly designs, drawings, and other engineering documentation.
• Continuously look for ways to make our CDU designs better performing, improve reliability, reduce costs, and increase efficiency.

Benefits

• Vacation and flex days, and paid company-wide shutdown during the holiday season.
• Comprehensive benefits including Dental, Drugs, Optical, Paramedical and Health Spending. These costs are covered by CoolIT and are enacted from your first day.
