About the Company

Founded in Calgary, Alberta in 2001, CoolIT Systems is the leading Direct Liquid Cooling technology provider for data centers, supercomputers, and desktop computers. We design and manufacture solutions used by the largest tech companies globally.

About the 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, and 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 CDU designs are delivered on time, meeting and exceeding market needs.
- Perform 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 explain 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 improve CDU designs—performance, reliability, cost, and efficiency.

Basic Qualifications

- Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or a 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 within liquid cooling, datacenter, HVAC, or building mechanical services industry.

Preferred Qualifications

- Understanding of designing parts and assemblies for high-volume production.
- Knowledge 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.
- Experience with process piping, P&ID;, and building mechanical design, particularly with respect to HVAC and fluid transfer.
- Knowledge of pump, motor, heat exchanger, and sensor selection, testing, and validation.




- Experience with rapid prototyping manufacturing techniques and testing of thermal/mechanical components; familiarity with lab equipment for data collection.

Skills

- Detail-oriented design calculations: heat transfer, fluid mechanics, piping design, stress/strain, and HVAC.
- Proficiency in CAD software (e.g., SolidWorks) for detailed mechanical designs & drawings.
- Experience with finite element computer simulations; CFD, heat transfer, and seismic analysis.
- Strong verbal, written, and interpersonal communication skills.
- Strong problem‑solving, analysis, and risk mitigation skills.
- Excellent time management and organizational skills.
- Knowledge of reliability analysis, tolerance stack‑up calculations, or statistical design tools such as design for lean six sigma is an asset.
- Attention to detail with thorough documentation to ensure all design requirements are covered, verified, and validated.

Perks

- Vacation and flex days, and paid company-wide shutdown during the holiday season.
- Comprehensive benefits including dental, pharmacy, optical, paramedical, and health spending—covered from your first day.
- Casual yet professional dress environment.
- Retention rewards such as “The Big Coffee Break” that reward tenure with additional vacation time and a monetary bonus.
- Company‑funded RRSP contributions to support long‑term financial goals.

Only candidates selected for an interview will be contacted. Successful candidates for this position will be required to undergo background checks including criminal records check and education verification.
