Mechanical Engineer

Company Overview

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.

Role Description

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.

Responsibilities:

• 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)

Requirements:

• 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 (SolidWorks/Fusion/Creo/NX or similar)
• Strong analytical/problem-solving skills and clear communication
• Ability to work effectively in a fast-moving, flexible environment

Preferred Qualifications:

• 2 years of industry experience in mechanical/thermal product development
• CFD experience (Solidworks Flow Simulation, FlowTherm, 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)

Application deadline: Applications accepted on an ongoing basis; posting will remain open until filled
