Mechanical Engineer

MicroRefrigeration Inc. · Scottsdale, Arizona

FULL TIME

Job Description

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.
