Overview

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. Recognized as one of “The Americas’ Fastest Growing Companies 2023” by Financial Times and honored with the Deloitte Fast 50 Clean Technology award in 2022, as well as the Deloitte Fast 500 distinction in both 2021 and 2022, CoolIT's rapid growth is capturing global attention.

As demand for generative AI, high performance computing and cloud solutions rapidly expands, there has never been a more exciting time to join our team.

We are looking for a Thermal Mechanical Engineer to join our team, reporting directly to the Thermal Mechanical Engineering Manager. In this key role, you will lead the design and development of innovative Direct Liquid Cooling solutions, including passive cold plate loops, manifolds, and modular components.

• Use thermal and mechanical engineering principles to lead the design and development of custom passive coldplate loops and rack & chassis manifolds, leveraging knowledge in heat transfer, fluid dynamics, ergonomics and manufacturability to optimize design outcomes.
• Foster close collaboration with cross‑functional teams and customers to ensure seamless integration of products into overall cooling system designs and effective project execution.
• Oversee the fabrication and testing of products, conduct experiments, collect data, and iterate designs to achieve desired thermal and mechanical performance.
• Aid in conducting comprehensive reviews of designs and drawings produced by junior team members, providing feedback on mechanical and thermal designs, drawing best practices and approving engineering drawings for use in manufacturing and assembly.
• Develop detailed engineering documentation, reports and articulate technical presentations to effectively communicate design concepts, testing outcomes and recommendations to both internal teams and external stakeholders.
• Utilize CAD, simulation tools and engineering principles to aid in mechanical and thermal design of cooling products, driving new product introduction (NPI) efforts from concept to mass production.

• Bachelor's degree in Mechanical Engineering.
• Minimum of 6 years of relevant experience in thermal/mechanical engineering with a P.Eng designation or similar professional.
• Highly proficiency in using CAD and simulation software (e.g. Solidworks, Celsius EC) to create detailed mechanical designs & drawings and predict & optimize performance.
• Solid understanding of fluid dynamic principles, especially as they relate to heat transfer and fluid flow in cooling systems.
• Proven ability to design components for mass production using a variety of manufacturing methods and engineering principles (Statistical tolerance analysis, GD&T, FMEA, DFM & DFA).

• A Master’s degree in a relevant thermal or fluid dynamics field is an asset.
• Experience in a mass production environment is an asset.

• Strong analytical and problem‑solving abilities, with a focus on data‑driven decision‑making.
• Experience in conducting experiments, analyzing results, and iterating designs based on findings.
• Excellent written and verbal communication skills.

We strive to be an employer of choice and as such we believe in rewarding our employees with career and development opportunities that will maintain and strengthen our culture while aligning to our vision and values.

• Vacation and flex days, and paid company‑wide shutdown during the holiday season.
• Comprehensive benefits including Dental, Drugs, Optical, Paramedical and Health Spending covered from the first day.
• Dress for your day – in a casual yet professional environment.
• Retention rewards like “The Big Coffee Break” that reward tenure with additional vacation time and a monetary bonus.
• Employee ownership program.

We thank every candidate in advance; however, only those 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.
