About the Role & Company
MicroRefrigeration Inc. is building next-generation datacenter cooling AI infrastructure solutions,
including proprietary compressed-refrigerant cooling technology that delivers superior efficiency
and density versus traditional direct liquid cooling systems.
We are seeking a Mechanical Engineer with strong design fundamentals, expert SolidWorks skills, and
practical experience with capital-equipment product release processes. This is a hands-on design
and build role. You will own mechanical design from concept through detailed design, drawings, BOM
creation, prototype fabrication support, and formal product release.
We are looking for a builder who is comfortable in a startup environment, moves quickly with
limited process overhead, and takes ownership of getting hardware designed, sourced, built, and
released.
No politics, just be a good engineer!
Key Responsibilities
Mechanical Design & SolidWorks
• Create high-quality 3D models, assemblies, and detailed manufacturing drawings in SolidWorks
(expert-level proficiency desired).
• Develop mechanical designs for refrigeration modules, cold plates, manifolds, server rack
integration, heater simulation assemblies, and supporting capital equipment.
• Apply DFM/DFA principles; produce drawings suitable for both prototype fabrication and
production release.
• Manage design data in PDM/PLM systems; maintain revision control, part numbering, and release
status.
Product Development & Release Process
• Own mechanical design deliverables through a formal Product Development Process (PDP) /
phase-gate process for capital equipment.
• Execute design reviews, design freeze, ECO/ECN processes, and transition from Engineering BOM to
Production BOM.
• Ensure designs meet manufacturing, cost, reliability, and scalability requirements for volume
production.
• Document design decisions, specifications, and as-built records that support final product
release.
Hands-on Build, Fabrication & Sourcing
• Support prototype builds in the Scottsdale facility — comfortable working with hands, measuring,
fitting, and debugging hardware.
• Source and order components and materials (McMaster-Carr fluency expected; also work with other
industrial suppliers).
• Create and maintain accurate BOMs; coordinate with technicians and suppliers for fabrication and
assembly.
• Iterate designs rapidly based on build feedback, test results, and manufacturing input.
Refrigeration & System Integration (Desired)
• Contribute to mechanical design of vapor-compression cooling systems, including compressor
modules, condensers, cold plates, and interconnecting plumbing.
• Collaborate with thermal, electrical, and controls engineers to deliver a complete, releasable
product.
Qualifications
• MSME, BSME, BSMET with ~5 years of mechanical design experience in capital equipment, industrial
machinery, HVAC/refrigeration equipment, or related hardware products.
• Expert-level SolidWorks skills — complex assemblies, drawings, configurations, and PDM
workflows. Ability to produce production-ready documentation is required.
• Demonstrated understanding of capital equipment product release processes, Product Development
Process (PDP), stage-gate or phase-gate methodologies, ECO/ECN, and design freeze practices.
• Hands-on experience with PDM and/or PLM systems for design data management and release.
• Comfortable building and fabricating equipment; able to work in a shop environment, support
prototype assembly, and debug mechanical issues.
• Practical experience ordering and specifying parts from McMaster-Carr and other industrial
suppliers.
• Refrigeration or HVAC mechanical design experience is strongly desired (vapor-compression
systems, cold plates, manifolds, condensers, or related components).
• Bachelor’s degree in Mechanical Engineering or equivalent practical experience.
• Startup or fast-paced product development environment experience preferred; ability to wear
multiple hats and deliver results with limited resources.
• Excellent communication skills and ability to document designs clearly for manufacturing and
cross-functional teams.
What We Offer
• Significant equity in a high-upside AI infrastructure venture.
• Opportunity to shape early engineering practices, product release methodology, and design
standards.
• Relocation support and the chance to work on groundbreaking cooling technology for AI
infrastructure.
• Competitive compensation commensurate with experience.
If you are a mechanical engineer with strong SolidWorks skills, real capital-equipment product
release experience, and a willingness to design, source, and help build hardware in a fast-moving
environment, we want to hear from you. Apply with your resume and a short note highlighting
relevant design and product-release work.
