Build the Future of Defence Sustainment

World Fuel Government Solutions is seeking a Defence Sustainment Engineer (Reliability & Supportability) to support the maintenance, reliability, supportability, and lifecycle management of complex Defence equipment and systems.

This role is ideal for a mechanically-minded engineer who enjoys understanding how equipment is designed, maintained, repaired, sustained, and improved throughout its operational life.

You will enjoy:
