• Perform daily rig inspections, routine maintenance, and minor repairs; report equipment issues promptly
• Locate utilities and set up sites in compliance with Colorado 811 and project safety plans
• Train and supervise a driller's helper
• Represent Triax professionally on client sites

What We're Looking For

• 3 years of geotechnical or environmental drilling experience, with hands-on time as the lead driller
• Experience with CME 55/75-class rigs (or equivalent) and hollow-stem auger sampling
• Air rotary and/or core drilling experience
• Monitoring well installation experience
• Valid driver's license with a clean driving record; CDL a plus
