- Maintain inventory of spare parts, fluids, and tooling; order replacements and manage parts storage.
- Conduct pre- and post-trip equipment inspections and complete maintenance logs and service reports.
- Assist drill crews with rig-up/rig-down, equipment troubleshooting in the field, and safe operation procedures.
- Ensure compliance with safety policies, lockout/tagout, confined space and fall protection protocols, and environmental regulations.
- Calibrate and maintain ancillary instruments (flow meters, pressure gauges, winch controllers) as required.
- Train operators in basic equipment care and report recurring issues to maintenance lead or supervisor.
Requirements
- High school diploma or equivalent; technical certificate, trade school, or associate degree in diesel technology, heavy equipment mechanics, or related field preferred.
