As part of the Hoffman family of companies, we partner with engineers, contractors, building owners, facilities teams, manufacturers, and fellow Hoffman companies to deliver reliable, sustainable heating and cooling systems. Hoffman Hydronics is a 100% employee-owned company through our ESOP, which means when we succeed together, every employee shares in that success.

Our culture is built on teamwork, shared accountability, innovation, mentorship, and a commitment to doing the job right. We are growing our Suwanee operation and are seeking a skilled, customer-focused technician to perform startup, warranty, troubleshooting, and field-service work while also providing in-house pump build and repair support.

The Start-up & Pump Build Technician is a field-service role responsible for factory-authorized startup, commissioning, warranty service, troubleshooting, performance verification, and customer training for commercial hydronic equipment. The technician works with boilers, water heaters, pumps, pump packages, booster systems, motors, VFDs, and related controls in commercial and institutional facilities.

In addition to regular field responsibilities, the technician will support the Suwanee pump shop approximately one to two days per week, as field schedules and customer commitments allow. Shop responsibilities include pump build, repair, testing, documentation, and coordination with parts and equipment needed for customer projects and repairs.

The successful candidate combines strong field-service judgment with hands-on mechanical ability. They use manufacturer installation manuals, wiring diagrams, control schematics, piping drawings, startup checklists, and measured operating data to confirm equipment is installed correctly, operating safely, and documented thoroughly.
