Impact Cooling is developing next-generation data center cooling using innovative direct-to-chip air cooling. Our approach is designed to reduce energy consumption and eliminate the need for liquid cooling infrastructure, cutting water use and simplifying deployment across a wide range of environmental conditions. By reducing reliance on water and traditional A/C equipment, our solution can significantly reduce total data center utility costs (deployment dependent).

Impact Cooling is leading sustainable advancements in cooling systems for a better and more efficient future.

We are seeking a full-time Mechanical Engineer to join our team on-site in Fort Collins, CO. The Mechanical Engineer will support the design, validation and implementation of mechanical and thermal solutions. The role includes numerical modeling, CFD, CAD design, hands‑on prototyping, manufacturing support, testing and analysis. In addition to these core responsibilities, you will help execute customer and government‑funded projects and take on other team responsibilities as needed.

This role may support U.S. government customers and defense‑related programs (e.g., DARPA). This role is open to new graduates. A Master’s degree is preferred, but not required.

• Design, validation, and implementation of mechanical and thermal solutions for high‑performance cooling products
• Create and iterate CAD models, assemblies, and drawings for prototypes and production‑intent hardware
• Plan and execute prototype build and test efforts; troubleshoot issues and drive design improvements
• Conduct thermal and mechanical validation testing (instrumentation setup, test execution, data analysis, reporting)
• Collaborate with cross‑functional teammates and external partners to translate requirements into reliable designs
• Perform CFD on CAD model to predict performance; design, build, test and compare against predicted data
• Support DFM/DFA efforts including tolerance considerations, BOMs, vendor communication, and build documentation
• Contribute to customer deliverables including integration support, test data packages, and technical documentation
• Assist with government‑funded project execution as applicable (milestones, validation plans, reporting inputs)

• Bachelor’s degree in Mechanical Engineering (Master’s preferred)
• Experience (academic, internship, or industry) in hardware design and development
• Familiarity with thermal systems, heat transfer fundamentals, and/or thermal testing methods
• CAD proficiency (Solid Works/Fusion/Creo/NX or similar)
• Strong analytical/problem‑solving skills and clear communication
• Ability to work effectively in a fast‑moving, flexible environment

• 2+ years of industry experience in mechanical/thermal product development
• CFD experience (Solidworks Flow Simulation, Flow Therm, ANSYS Fluent/Icepak)
• Experience with electronics cooling (heat sinks, forced convection, fans/blowers, packaging)
• Experience taking hardware from prototype to production (DFM/DFA, suppliers, drawing release)
• Experience helping bring a new thermal/cooling technology to market

Compensation: $60,000–$75,000 (base) + (equity if applicable)

Benefits: health insurance reimbursement up to $500/month, and unlimited PTO (as approved)
