Excellent verbal and written communication skills to effectively translate complex technical data to technicians, management, and parts personnel.

Must maintain the mobility required to inspect heavy equipment alongside technicians, work safely around heavy machinery, and provide technical oversight directly at the vehicle or repair bay.
Strong capability to prioritize workshop tasks within a set budget, maintain a high degree of patience, offer constructive feedback to developing technicians, and foster a collaborative, safety-first working relationship.
Valid work authorization in the country where the job is located is required.
