Brazer

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 Brazer joins, fabricates, and assembles refrigeration and piping components for commercial and industrial HVAC/R applications. This includes layout, brazing, soldering, swaging, flaring, pressure testing, and ensuring all work meets code, safety standards, and system specifications. The role draws on the refrigeration piping discipline—installing copper, steel, and related materials—and requires strong, repeatable brazing technique and the ability to work independently or as part of an installation team.

Key Responsibilities:

Braze, solder, swage, flare, and thread piping to meet system design requirements.

Join refrigeration and piping components according to blueprints, work orders, and layout specifications.

Prepare pipe layouts based on blueprints, schematics, and instructions.

Install components such as valves, strainers, receivers, oil separators, coils, and line sets.

Perform pressure testing and leak detection on newly installed piping; evacuate and prepare systems for charging.

Safely operate cutting tools, threading machines, torches, and brazing equipment.

Inspect joints, fittings, and supports to verify quality workmanship and code compliance.

Document work completed and any issues encountered; maintain a clean, organized work area.

Adhere to OSHA guidelines, company safety policies, and refrigerant handling regulations.
