  VDC control circuits to 480
  
  VAC power systems.
• Diagnose and repair mechanical, pneumatic, hydraulic, and electromechanical system issues.
• Read and interpret electrical schematics, wiring diagrams, mechanical drawings, and installation instructions.
• Verify proper installation and functionality of modified systems through testing and commissioning activities.
• Identify root causes of failures and implement corrective actions in accordance with engineering requirements.
• Conduct system testing, inspections, and operational validation to ensure equipment meets performance and safety standards.
• Generate clear documentation of work performed, deficiencies identified, corrective actions taken, and commissioning results.
• Support startup, commissioning, warranty, and field service activities at customer sites.
• Work independently with minimal technical guidance while maintaining high-quality workmanship and strict adherence to safety procedures.
• Execute field modifications in alignment with engineering change documentation and technical requirements.
• Apply software-assisted diagnostics and fault analysis where applicable to support commissioning and troubleshooting activities.

• Strong working knowledge of electrical systems from 24
  
  VDC through 480
  
  VAC.
• Proven troubleshooting experience involving electrical, mechanical, and electromechanical systems.
• Ability to read and understand electrical schematics, wiring diagrams, technical manuals, and engineering documentation.
• Ability to perform field modifications and validate system functionality based on engineering requirements.
• Skilled in the use of electrical test equipment including multimeters, clamp meters, insulation testers, and related diagnostic tools.
• Mechanical aptitude with experience using hand tools, power tools, and precision measuring equipment.
• Ability to work independently, prioritize tasks, and solve complex technical problems with limited guidance.
• Strong attention to detail and commitment to safety and quality standards.
• Electrical troubleshooting capability across control and power circuits.
• Mechanical troubleshooting capability for complex assemblies and systems.
• Ability to interpret and apply technical documentation in the field.
• Competence in root cause analysis and structured problem solving.
• Experience performing commissioning testing and verification of system performance.
• Consistent adherence to safety and quality compliance requirements.

• Experience commissioning rail vehicles, transit systems, industrial equipment, or other complex electromechanical systems.
• Ability to perform software-assisted diagnostics and fault analysis.
• Familiarity with CAN communication networks, PLC controls, or vehicle control systems.
• Previous field service or startup and commissioning experience in a customer-facing environment.
• Experience with software diagnostics tools used in rail or industrial control applications.
• Comfort working in dynamic field environments where priorities and tasks can change rapidly.

This role is primarily field-based and involves working on rail vehicles and associated equipment in operational and commissioning environments. The Commissioning Technician works with a range of electrical and mechanical systems, using diagnostic tools such as multimeters, clamp meters, insulation testers, hand tools, power tools, and precision measuring instruments. The work may take place in rail yards, workshops, or customer facilities, requiring strict adherence to safety procedures and quality standards.

The environment can be fast-paced and hands-on, with frequent interaction with customer personnel during startup, commissioning, warranty and field service activities. Technicians are expected to maintain professional conduct, follow site safety rules, and wear appropriate protective equipment…
