Senior Certification Engineer

Gradian is an engineering-led, full-line thermal solutions partner serving data center and other mission-critical, commercial, and industrial markets. Headquartered in Maple Grove, MN, with additional facilities across North America, we design and manufacture liquid cooling systems, air handling equipment, heat rejection units, and modular, factory-assembled thermal management solutions.

Gradian was founded through the unification of four complementary, established brands: MAS HVAC, Daedex, DeepCoolAI, and Eco Chillers. Together, we act as a single-source provider, deploying cooling technologies as scalable systems optimized for efficiency, spatial constraints, and overall performance. With a vertically integrated engineering and manufacturing model, we pair rapid design turnaround with precision fabrication, so customers can move faster on complex projects where reliability, timeline, and quality all matter.

Why work here

At Gradian, you'll work alongside others who get genuinely fired up by complex problems, see your work go from first sketch to job site in weeks, not years, and know that while we're developing the technologies critical for AI infrastructure to scale, our culture remains people-first by design.

It is core to our identity that we operate as one team — driving to win together, energizing others, and building lasting relationships that make the work fun and rewarding.

Position Summary:

We are seeking a Sr Certification Engineer to lead product certification and regulatory compliance strategy across Gradian’s liquid cooling, air handling, and chiller product lines. This role owns certification planning from concept through sustaining engineering, translates regulatory and standards requirements into actionable design inputs, and coordinates testing, technical documentation, agency submissions, audits, and product release readiness. The position partners with NPD, R&D, Test & Integration, Quality, Operations, Product Management, suppliers, accredited laboratories, and certification bodies to secure and maintain market access while reducing certification risk, cost, and schedule impact.

Key Responsibilities:

Own certification strategy, scope, budgets, schedules, and deliverables for new-product development, product changes, and sustaining programs across liquid cooling, air handling, and chiller platforms.

Determine applicable North American and international requirements by product architecture, voltage, refrigerant or coolant, pressure boundary, controls, installation, and target market; document the rationale in certification plans and compliance matrices.

Serve as the technical interface with Nationally Recognized Testing Laboratories, certification bodies, AHRI, authorities having jurisdiction, external test laboratories, customers, and suppliers.

Lead certification projects for applicable product-safety frameworks, including UL/cUL/CSA and IEC requirements; address UL/CAN/IEC 62368-1 for data-center coolant distribution equipment and UL/CAN/IEC 60335-2-40 or UL 1995 where applicable to HVACR equipment.

Lead performance certification and rating activities for applicable air and chiller products, including relevant AHRI programs and standards such as AHRI 550/590 for water-cooled and air-cooled chillers.

Define and review compliance test plans covering electrical safety, mechanical integrity, pressure and leak performance, abnormal operation, thermal performance, controls, EMC, environmental, reliability, and product-specific requirements.

Review schematics, layouts, bills of material, drawings, P&IDs, software or controls requirements, labels, installation instructions, and technical files; identify gaps early and drive practical corrective actions with engineering teams.
