Job Title: Controls Technician Job Description This Controls Technician role focuses on troubleshooting, diagnosing, repairing, and maintaining electrical and automation control systems on mobile asphalt production and road construction equipment. You will support equipment both in the shop and in the field, identify root causes of electrical and control issues, and ensure machines operate safely, reliably, and efficiently.
This position is ideal for a hands-on technician experienced with PLC-based control systems, electrical circuits, sensors, HMIs, and automation components on mobile industrial or heavy construction equipment. Responsibilities Troubleshoot and repair electrical, controls, and automation systems on asphalt plants, pavers, milling machines, and other mobile equipment. Diagnose issues involving PLCs, HMIs, sensors, VFDs, motor controls, wiring, and communication networks.
Read and interpret electrical schematics, wiring diagrams, and control drawings to support accurate troubleshooting and repair. Perform equipment commissioning, startup, testing, and system verification for new or modified systems. Assist with software, PLC, and HMI updates and modifications to improve system performance and reliability. Support field service efforts by responding to equipment issues at customer job sites as needed.
Conduct root cause analysis on recurring failures and implement corrective actions to prevent future issues. Troubleshoot hydraulic and electromechanical systems integrated with machine controls. Perform preventative maintenance inspections and repairs on mobile equipment control systems. Maintain accurate service records, troubleshooting documentation, and repair reports for all work performed. Coordinate with engineering, manufacturing, and service teams to resolve complex technical issues and support continuous improvement.
Use diagnostic tools such as multimeters, clamp meters, and communication troubleshooting software to identify and resolve faults. Travel to customer sites, as required, to support field installations, commissioning, and service calls. Essential Skills Strong troubleshooting experience with mobile equipment, heavy machinery, or industrial equipment controls systems. Hands-on experience working with DC-powered electrical systems (12VDC, 24VDC, and other DC control circuits).
Experience diagnosing and repairing electrical faults on mobile equipment control systems, including wiring, sensors, relays, actuators, and machine control components. Demonstrated ability to perform advanced root cause analysis on electrical, controls, and machine performance issues. Additional Skills & Qualifications Hydraulic troubleshooting experience, including diagnosing issues within hydraulic systems integrated with electronic controls and automation systems.
Experience troubleshooting electro-hydraulic systems on mobile or heavy equipment. Strong mechanical aptitude with the ability to diagnose issues across electrical, hydraulic, and mechanical systems. Experience supporting and troubleshooting mobile construction equipment, asphalt equipment, aggregate equipment, mining equipment, or similar off-road machinery. Familiarity with machine control systems utilizing sensors, hydraulic valves, engine controls, HMIs, and PLCs.
Ability to troubleshoot equipment in both shop and field environments with minimal supervision. Experience working on DC-powered machinery is highly preferred; AC power experience is considered a plus. Strong understanding of machine diagnostics and fault-finding methodologies for complex mobile equipment. Allen-Bradley, Siemens, or other PLC programming and troubleshooting experience. Knowledge of industrial communication protocols such as CAN Bus, Ethernet/IP, and Modbus.
Familiarity with hydraulic systems and engine controls integrated with electronic control systems. Work Environment This role combines work in a manufacturing environment with field service assignments at customer job sites.
