Industrial Controls and Instrumentation Technician

Shape safe, reliable operations as our Industrial Controls and Instrumentation Technician

Each day at our Rollinsford, NH facility starts with safety. You’ll open your toolbox, review the day’s permits, and head to the process units to calibrate instruments, inspect loops, and verify signals. Before lunch, you might trace a control fault through a PLC routine, replace a finicky transmitter, and document your findings. In the afternoon, you could be installing power and control cabling to a new motor control center, updating panel drawings, and closing out PMs—always with housekeeping, lockout/tagout, and life-critical rules top of mind.

• Lead with safety: follow all policies, procedures, and best practices every time.
• Troubleshoot and correct instrumentation and control issues across plant systems.
• Execute preventive maintenance and perform precise calibrations on field instruments.
• Create and maintain accurate logs, calibration records, and maintenance documentation.
• Install new control systems and associated power wiring.
