Safety First: Conduct pre-task safety planning and strictly adhere to all site-specific safety protocols.

Requirements

Motivation to Learn: High interest in construction and engineering; willingness to study for and obtain industry certifications.

Communication: Strong verbal and written skills for reporting technical data to project stakeholders.

Physical & Driving: Ability to drive a company vehicle (comparable to a Ford F-150) and perform physical tasks on active construction sites.
