Overview
Senior Mechanical Engineer Jobs in Greater Toronto Area, Canada at DeepCoolAI
Title: Senior Mechanical Engineer
Company: DeepCoolAI
Location: Greater Toronto Area, Canada
About the Company
DeepCoolAI delivers high-efficiency liquid-cooling solutions—Rear-Door Heat Exchangers (RDHx), Coolant Distribution Units (CDUs), Load Banks, and Service Carts—designed for hyperscale, HPC, and AI data centers.
About the Role
We are seeking a Senior Mechanical Engineer to lead the mechanical design, development, and release of DCAI’s liquid-cooling equipment. You will own major assemblies and end-to-end engineering execution—from concept and analysis through prototype, validation, manufacturing release, and field support—while mentoring junior engineers and partnering closely with Electrical, Controls, Manufacturing, Quality, Supply Chain, and Sales.
Responsibilities
- Technical leadership & ownership
- Lead mechanical design for RDHx, CDUs, and related platforms from concept to production release.
- Own subsystem architecture, requirements, design tradeoffs, and technical decision-making.
- Mentor engineers and review models/drawings for quality, safety, and manufacturability.
- Design, analysis, and validation
- Produce robust 3D CAD, manufacturing drawings, GD&T, tolerance stacks, and BoMs.
- Perform/oversee thermal and fluid calculations (heat transfer, pressure drop, airflow, pump selection), and guide test plans to validate performance.
- Drive design verification testing (DVT), reliability testing, failure analysis, and corrective actions.
- DFM/DFA & production readiness
- Partner with manufacturing and suppliers to optimize designs for cost, lead time, and quality.
- Create and maintain engineering documentation, revision control, and release packages (ECR/ECO workflows).
- Support NPI builds, pilot runs, and continuous improvement initiatives.
- Cross-functional collaboration
- Collaborate with Electrical and Controls teams to ensure mechanical designs integrate cleanly with sensors, wiring, enclosures, and automation.
- Support customer-facing technical work: reviewing specs, responding to RFIs, and contributing to proposals/quotes (as needed).
- Supplier & stakeholder management
- Lead supplier technical communication for fabrication, machining, sheet metal, welding, coatings, and assemblies.
- Identify technical risks early and drive mitigation through FMEA and structured problem solving.
Qualifications
- B.Sc. in Mechanical Engineering (or equivalent).
- 7+ years of relevant mechanical engineering experience (industrial equipment, thermal/fluid systems, HVAC/liquid cooling, or similar).
- Strong proficiency in SolidWorks (or equivalent 3D CAD) and drawing release practices (GD&T, tolerance stack-ups, BoMs).
- Demonstrated experience taking products from prototype to production (NPI, DFM/DFA, supplier builds, validation testing).
- Solid fundamentals in thermodynamics, heat transfer, and fluid mechanics; comfortable with pump/coil/fan selection and pressure-drop analysis.
- Excellent communication skills and ability to work cross-functionally in a fast-paced environment.
Required Skills
- Experience with data center cooling, liquid-cooled racks, or high-power thermal management.
- Familiarity with sheet metal, piping, weldments, and enclosure design.
- Exposure to simulation tools (FEA/CFD/thermal) and test instrumentation/data analysis.
- Knowledge of relevant standards (e.g., ASHRAE thermal management guidance).
- P.Eng (Canada) / PE (U.S.) or eligibility in progress.
Preferred Skills
- Build next-generation cooling solutions for the AI/HPC era in a highly applied, product-driven environment.
- High ownership, rapid iteration, and direct impact on real customer deployments.
- Remote-friendly culture with strong collaboration across engineering disciplines.
