• Preferred: Technical or trade certification in mechanical maintenance or related field; Experience leading crews or mentoring technicians; Experience coordinating major maintenance or shutdown work; Advanced condition monitoring experience (vibration, thermography, oil analysis).

Work environment/physical demands include:

• Field-based role in an active processing plant environment
• Working around heavy industrial equipment and rotating machinery
• Walking on uneven surfaces, climbing stairs and ladders
• Exposure to dust, noise, heat, and varying weather conditions
• Exposure to mechanical hazards including moving equipment and material handling
• Ability to wear required personal protective equipment (PPE) in operational areas

All candidates will be required to complete a pre-employment medical exam, drug and alcohol test, and background check. All positions require a pre-placement physical examination to ensure candidates are 'fit for duty'. Additional training and/or testing may be required.
