Skill: Mechanical Engineer

Summary

A Mechanical Engineer applies engineering principles to design, analyse, and support physical systems and mechanical components.
They ensure systems perform reliably, safely, and efficiently across their intended lifecycle.

Scope of Practice

A Mechanical Engineer may work on:

• Mechanical components and assemblies
• Structural and load-bearing systems
• Thermal and fluid systems
• Machinery and equipment
• Manufacturing and production systems
• Maintenance, reliability, and lifecycle planning

Work spans concept → design → validation → manufacture → operation → improvement.
