Job description

The Heavy Equipment Hydraulic Specialist is responsible for the advanced diagnosis, troubleshooting, repair, and overhauling of complex hydraulic systems and components on heavy construction machinery. This role ensures optimal machine performance, safety, and minimal downtime. While working across various heavy equipment brands, a strong specialization and technical familiarity with Volvo Construction Equipment (Volvo CE) is highly preferred. Additionally, the role requires integrated knowledge of electrical systems to effectively diagnose modern, electro-hydraulic machinery.

Duties and Responsibilities:

1. Diagnostic Troubleshooting: Perform advanced diagnostics on complex hydraulic and electro-hydraulic systems to identify, isolate, and repair technical faults.
2. Component Overhauling: Disassemble, inspect, repair, rebuild, and reassemble heavy-duty hydraulic components, including pumps, motors, control valves, cylinders, and steering systems.
3. Schematic Interpretation: Read, interpret engineering drawings, complex hydraulic and electrical circuit diagrams.
4. Electrical Integration: Diagnose and repair electrical faults related to hydraulic control systems, including wiring harnesses, sensors, solenoids, and electronic control units (ECUs).
5. Preventative Maintenance: Execute scheduled maintenance, system flushes, pressure testing, and calibrations to maximize equipment lifespan and operational safety.
6. Documentation & Reporting: Maintain accurate records of all maintenance activities, parts used, diagnostic readings, and repair times using the company’s asset management software and the ability to write professional reports.

Skills and Competencies:

1. Technical Expertise: Deep knowledge of fluid power principles, closed-loop systems, and proportional valves.
2. Electrical Proficiency: Strong fundamental understanding of DC electrical circuits, digital multimeter usage, and reading electrical schematics.
3. Analytical Thinking: Exceptional problem-solving skills with the ability to trace multi-system faults (mechanical, hydraulic, and electrical interfaces).
4. Precision Tools: Proficient in using specialized diagnostic tools, flow meters, pressure gauges, and electronic calibrators.
5. Safety & Compliance: Thorough understanding of workshop safety practices, hazard identification, and proper disposal of hazardous fluids.

• Education: Diploma or technical certification in Mechanical Engineering,
• Experience: Minimum of five years of hands-on experience as a hydraulic technician working 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 software (e.g., Volvo Tech Tool) is strongly preferred.
• Certifications: Certified Fluid Power Hydraulic Specialist (CFPHS) or equivalent industry certification is highly advantageous.

Physical Requirements

• Ability to lift heavy components and work in restricted or awkward physical positions.
• Capability to work in diverse environment conditions, including both workshop settings and outdoor field locations
