Automation and Controls Field Service Technician

Overview

Company Summary

Founded in 1980 by Geoffrey Sherwood and Charles Logan as a manufacturers' representative for over ten companies in the mid-Atlantic region, Sherwood-Logan has grown into one of the premier providers of water and wastewater treatment equipment. Our teams include degreed engineers, licensed Professional Engineers, and respected industry professionals across four offices from Virginia to Connecticut, with more than 500 years of combined water/wastewater experience.

In 1984, we added S-L Controls, a systems integration division dedicated to the municipal water and wastewater market. Since then, we have delivered nearly 1,500 instrumentation and control systems projects, ranging from small pump station control panels to plant-wide SCADA systems. In 2019, Sherwood-Logan became part of the Vessco family of companies, positioning us for continued growth within a broader network of water and wastewater specialists.

The Automation and Controls Field Service Technician is responsible for supporting the reliable operation of automation, electrical, instrumentation, and mechanical equipment at municipal and industrial water and wastewater treatment facilities throughout the Mid-Atlantic region. This role installs, calibrates, troubleshoots, and maintains process instrumentation, control panels, motor control systems, and PLC/SCADA platforms, working independently in the field and managing multiple service tasks across customer sites.

Frequent overnight travel is required.
