Mechanical Engineer

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.

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.

MicroRefrigeration is an equal opportunity employer.
