Field Service Engineer - Rotary UPS

At IEM, we’re not just building innovative electrical distribution systems, we’re shaping the future. IEM is dedicated to delivering world‑class solutions for complex power needs. After 75 years, we continue to push the boundaries of what’s possible. Whether you’re an experienced professional or just starting out, you’ll have the opportunity to contribute, grow, and make a lasting impact on industries that power the world’s most dynamic markets.

The Senior Field Service Engineer – RUPS Systems will specialise in rotary UPS power system distribution builds, mechanical and generator integration, system integration, start‑ups, and preventative maintenance programmes. This role requires advanced technical expertise, mechanical aptitude, leadership skills, and hands‑on field experience with both electrical control systems and rotating equipment such as generators and flywheels. Strong troubleshooting skills and a commitment to delivering high‑performance power solutions in data centres, hospitals, industrial facilities and utility‑scale environments are essential.

This is not a typical UPS engineer or technician role. In fact, a strong background in traditional static UPS systems may not be advantageous for this position. The ideal candidate will have relevant experience with mechanical systems, generators and rotary equipment, and be comfortable commissioning complex power systems in the field. You will act as the front‑line expert for bringing large‑scale RUPS systems online, resolving technical issues and training others.

This role will also provide technical software and hardware troubleshooting support to the IEM customer base on‑site throughout North America while performing start‑ups, retrofits or preventative maintenance. The engineer will work closely with cross‑functional IEM teams to integrate current and new technologies, commission complex generator and RUPS systems, optimise existing power infrastructure and ensure seamless operation across our power products as defined by the customer’s RUPS design and sequence of operations (SOO).

This role will serve as the point of contact for all field service personnel related to RUPS start‑up, generator support, preventative maintenance, 24‑hour emergency response and remote technical assistance.
