While working across various heavy equipment brands, a strong specialization and electrical familiarity with Volvo Construction Equipment (Volvo CE) systems is highly preferred. Additionally, the role requires integrated knowledge of hydraulic systems to effectively diagnose modern, electro-hydraulic machinery.

Duties and Responsibilities:

1.Diagnostic Troubleshooting: Perform advanced electrical diagnostics on heavy machinery using digital multimeters, oscilloscopes, and specialized software to isolate open circuits, short circuits, and communication faults.

2.System Programming & Calibration: Configure, calibrate, and program electronic control units (ECUs), displays, and safety systems following component replacements or software updates.

3.Schematic Interpretation: Read, analyze, and accurately interpret complex electrical wiring diagrams, circuit schematics, and technical network architecture maps.

4.Hydraulic Integration: Diagnose and repair electrical faults directly impacting hydraulic control systems, including electronic proportional valves, solenoids, pressure sensors, and joysticks.

5.Harness & Component Repair: Rebuild, repair, or replace damaged wiring harnesses, connectors, fuse panels, alternators, starter motors, and electronic sensors to OEM standards.

6.Documentation & Reporting: Maintain accurate records of all electrical modifications, software versions, and diagnostic logs using the company’s asset management

Skills and Competencies:

1.Technical Expertise: Deep knowledge of DC electrical systems (12V/24V), CAN-bus networks (J1939), multiplexing, and electronic control topologies.

2.Hydraulic Proficiency: Strong fundamental understanding of fluid power principles, electro-hydraulic valves, and how electrical signals drive hydraulic functions.

3.Analytical Thinking: Exceptional problem-solving skills with the ability to trace multi-system faults across complex mechanical, hydraulic, and electronic interfaces.

4.Precision Tools: Proficient in using specialized diagnostic laptops, electronic scanners, communication adapters, and precision testing equipment.

5.Safety & Compliance: Thorough understanding of electrical safety protocols, lockout/tagout procedures, battery handling safety, and electrostatic discharge (ESD) protection.

• Education: Diploma or certification in Electrical Engineering, Electronics Engineering, Automotive Electrics, or a related technical field.
• Experience: Minimum of five years of hands-on experience as an auto-electrician working specifically with heavy construction equipment (e.g., excavators, wheel loaders, articulated haulers).
• Brand Specialization: Proven track record working with Volvo Construction Equipment (Volvo CE) systems and diagnostic software (e.g., Volvo Tech Tool) is strongly preferred.
• Certifications: Certified Heavy Equipment Electrical Technician or equivalent industry-recognized electronics certification is highly advantageous.

Physical Requirements:

• Capability to work in diverse environmental conditions, including both workshop settings and outdoor field locations.
