Mechanical Engineer, EIT

WHAT YOU’LL DO: Role: The Mechanical Engineer role at CoolIT Systems focuses on designing and developing advanced Coolant Distribution Units (CDUs) for direct liquid cooling systems. You will support the full product lifecycle—from concept through production—while collaborating with cross-functional teams and partners. The role emphasizes continuous improvement to enhance performance and manufacturability. Ideal candidates bring a strong mechanical engineering foundation, proficiency in CAD and simulation tools, and effective communication skills. 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 Basic Qualifications: Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or directly related discipline. Registration as an EIT with APEGA, or eligibility to obtain EIT status within 12 months. Minimum of 3 years relevant mechanical engineering experience, ideally in a product design role relevant to liquid cooling, datacenter, HVAC, or building mechanical services industry. Preferred Qualifications: 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. Skills: Detailed design calculations; heat transfer, fluid mechanics, piping design, stress/strain, and HVAC. Proficiency in using CAD software (e.g., SolidWorks) for detailed mechanical designs & drawings. Proficiency with finite element computer simulations; CFD, heat transfer, and seismic analysis. Effective verbal, written, and interpersonal communication skills. Strong problem-solving, analysis, and risk mitigation skills. Excellent time management and organizational skills. Reliability analysis, tolerance stack-up calculations, or statistical design tools like design for lean six sigma would be an asset. Attention to detail and documentation to ensure that all design requirements are covered, verified, and validated. WHY COOLIT?
