Senior Electrical 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:

The Senior Electrical Engineer provides ownership for the electrical design of engineered liquid cooling solutions. Highly independent specialist and technical leader for NPD platforms delivering liquid cooling products for data center applications. Leads electrical architecture, standards application, validation rigor, and mentoring to ensure safe, compliant, manufacturable designs for shippable units.

Essential Responsibilities
• Own assigned product and project electrical scope end-to-end, including requirements, architecture, detailed design, calculations, documentation, release, manufacturing support, and verification.
• Establish electrical architecture for assigned products and projects, including power distribution, protection, panel topology, grounding and bonding, safety circuits, instrumentation, motors, pumps, and VFD integration.
• Independently review and release complete electrical design packages, including schematics, wiring diagrams, panel layouts, cable schedules, calculations, bills of materials, and release records.
• Review and approve work completed by Electrical Engineers, including calculations, component selection, drawings, and design packages.
• Perform and approve electrical load and feeder calculations, conductor and overcurrent-protection sizing, SCCR evaluations, control transformer and power-supply sizing, voltage-drop calculations, panel thermal-load calculations, motor and VFD sizing, grounding and bonding design, and electrical inputs supporting arc-flash analysis.
• Independently interpret and apply applicable requirements, including NFPA 70, NFPA 70E, UL 508A, IEC 60204-1, applicable CSA requirements, and customer-specific requirements; contribute improvements to Gradian electrical standards.
• Develop electrical verification requirements, acceptance criteria, and test procedures; support Test & Integration during system-level validation, FWT/FAT, compliance, and certification activities.
• May lead manufacturing-floor troubleshooting, structured root-cause investigations, disposition of electrical nonconformances, and production-related design changes.
• Independently review supplier submittals, panel-builder documentation, component substitutions, deviations, and alternate-component proposals.
• Mentor Electrical Engineers, lead technical reviews, and reinforce…
