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 Electrical Engineer supports the electrical hardware design, integration, and programming of control systems for air cooling equipment, including air handling units, fan arrays, direct expansion (DX) units, and related equipment. This role works under the guidance of senior engineering staff to implement well-defined tasks across controls hardware, controller, display, software, testing, and documentation. Supports new product development (NPD) for air-cooled HVAC OEM equipment, such as air handling units (AHUs), computer room air handlers (CRAHs), DX computer room air conditioners (CRACs), condensing units, and fan walls, used in data center and commercial applications.

Contributes to electrical design documentation, component selection support, BOM creation, prototype build support, and verification activities under guidance from senior engineers.

Key Responsibilities:

• Support electrical design for power distribution, control panels, instrumentation/sensors (temperature, humidity, airflow, differential pressure), damper actuators, refrigerant pressure/temperature sensors and safety switches, electronic expansion valves (EEVs), and VFD/EC fan motor and compressor (fixed-speed and inverter-driven) interfaces within shippable product units.
• Create and update electrical schematics, wiring diagrams, panel layouts/GA drawings, and cable schedules using AutoCAD (preferred) or similar CAD tools.
• Build and maintain bills of materials (BOMs), including part documentation, alternates, and revision updates.
• Support prototype and pilot builds: verify wiring, assist with troubleshooting wiring issues, and document corrections.
• Contribute to test documentation including FAT/SAT checklists, test procedures (including fan, airflow, and DX refrigeration circuit run testing), and inputs to O&M documentation.
• Collaborate cross-functionally with mechanical, thermal/airflow, refrigeration, and controls teams; maintain clear and detailed engineering documentation.

Qualifications & Requirements:

Required:

• Bachelor’s degree in Electrical Engineering (or closely related).
• 3+ years of professional electrical engineering experience, preferably in HVAC, industrial equipment, or OEM manufacturing environments.
• Proficiency in electrical CAD software, with AutoCAD Electrical preferred (SOLIDWORKS Electrical…
