Defence Sustainment Engineer

Location: Melbourne, Australia

Work Arrangement: Hybrid (Tuesday-Thursday in office)

About The Role

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

This role is ideal for a mechanically-minded engineer who enjoys understanding how equipment is built, maintained, supported, and improved throughout its operational lifecycle.

We are particularly interested in engineers with experience supporting, maintaining, improving, or managing complex assets and equipment within Defence or related industries such as Rail, Marine, Oil & Gas, Utilities, Manufacturing, Heavy Industry, Mining, Transportation, or Asset Management environments.

Working within our Defence Engineering team, you will contribute to the sustainment and long-term support of complex systems through activities including maintenance planning, asset management, reliability improvement, engineering investigations, lifecycle management, and supportability engineering.

Unlike larger Defence organisations where engineers are often limited to a single discipline, this role provides broad exposure across sustainment engineering, reliability, maintenance, supportability, lifecycle management, systems engineering, configuration management, and Defence support programs. You will work closely with experienced engineers, Defence customers, suppliers, and project teams while developing a broad understanding of how Defence capability is designed, maintained, and supported throughout its service life.

This is an excellent opportunity for an engineer looking to broaden their experience, solve practical engineering problems, work on complex physical assets, and build a long-term career within Defence engineering and sustainment.

What You'll Be Doing

• Support sustainment and lifecycle engineering activities across Defence programs.
• Contribute to maintenance planning and asset management activities.
• Assist with reliability, maintainability, and supportability engineering tasks.
• Support investigations into equipment performance, failures, and maintenance-related issues.
• Participate in root cause analysis and problem-solving activities involving complex mechanical systems.
• Develop and maintain engineering documentation, maintenance records, technical data, and supportability information.
• Support engineering change and configuration management activities.
• Assist with development of maintenance concepts, support strategies, and lifecycle planning.
• Support preparation of technical publications, operating instructions, and maintenance documentation.
• Work closely with Systems Engineers, suppliers, project teams, and Defence stakeholders.
• Contribute to continuous improvement initiatives focused on safety, reliability, maintainability, and operational performance.

What We're Looking For

Required Qualifications

• Degree in Mechanical Engineering, Aerospace Engineering, Systems Engineering, Electrical Engineering, or related engineering discipline.
• 3+ years of engineering experience supporting, maintaining, improving, or managing complex equipment, assets, or systems.
• Experience in one or more of the following:
• Maintenance Engineering
• Asset Management
• Reliability Engineering
• Sustainment Engineering
• Supportability Engineering
• Lifecycle Engineering
• Root Cause Analysis (RCA)
• Understanding of engineering fundamentals, asset lifecycle management, maintenance principles, and reliability concepts.
• Experience working with mechanical systems, industrial equipment, engineered assets, vehicles, machinery, plant equipment, or other complex physical systems.
• Strong analytical and problem-solving capability.
• Strong written and verbal communication skills.
• Ability to work effectively within multidisciplinary engineering teams.

Examples of Relevant Backgrounds

Successful Candidates May Have Experience

• Managing maintenance programs for industrial, marine, rail, Defence, manufacturing, or energy-related assets.
• Supporting asset reliability and lifecycle management activities.
• Planning preventive and corrective maintenance programs.
• Conducting root cause investigations and reliability improvement initiatives.
• Supporting sustainment, maintenance, or engineering support programs.
• Working with mechanical equipment, rotating machinery, transportation systems, mobile assets, plant equipment, or industrial facilities.

Preferred Qualifications

• Experience within Defence, Aerospace, Rail, Marine, Oil & Gas, Utilities, Manufacturing, Mining, or other highly regulated industries.
• Exposure to Defence sustainment programs, Integrated Product Support (IPS), Integrated Logistics Support (ILS), or other asset support and lifecycle management activities.
• Experience participating in engineering investigations, reliability studies, or failure analysis activities.
• Exposure to maintenance planning, supportability assessments, or asset lifecycle planning.
• Exposure to engineering change processes or configuration-controlled environments.
• Experience developing engineering documentation, technical publications, maintenance instructions, or user manuals.

What Makes Someone Successful in This Role

• Strong mechanical aptitude and curiosity about how equipment is maintained and supported.
• Ability to solve practical engineering problems using a structured and analytical approach.
• Interest in reliability, maintenance, asset performance, and lifecycle engineering.
• Strong attention to detail and commitment to engineering quality.
• Comfortable working across multiple engineering disciplines and stakeholder groups.
• Eagerness to learn and develop within the Defence engineering environment.

Why Join World Fuel Government Solutions?

• Work directly on Defence engineering and sustainment programs.
• Gain exposure across engineering, supportability, reliability, maintenance, and lifecycle management.
• Learn from experienced Defence engineers and technical specialists.
• Develop broad engineering capability rather than working within a narrow specialty.
• Enjoy significant ownership, responsibility, and visibility early in your career.
• Work in a collaborative, highly supportive engineering team.
• Build a long-term career within Defence engineering and sustainment.
