What Does a Mechanical Engineer Do?
A mechanical engineer, along with mechanical trades professionals, plays an important role in creating and improving mechanical systems across a range of industries. Their work ensures that everything from machinery to heating systems operates safely and efficiently in our modern world. Trades roles, such as mechanical fitter, welder or maintenance technician, offer hands-on expertise to bring these systems to life and keep them running effectively.
What is Mechanical Engineering?
Mechanical engineering is a branch of engineering focused on designing, analysing and manufacturing mechanical systems. It covers activities such as developing engines, building machinery and creating effective ventilation and air conditioning systems. Degree-qualified engineers often lead in-depth design and planning, while trades professionals contribute practical skills needed for fabrication, installation and maintenance.

Mechanical Engineer Job Scope
Mechanical engineers and trades professionals work together to enhance and optimise mechanical systems for society’s evolving needs. Below are the key responsibilities that define a typical mechanical engineering setting:
Designing Mechanical Systems
Mechanical engineers create concepts and 3D models for products and systems. They develop detailed plans for parts and assemblies. Trades specialists, such as fitters and machinists, then use these plans to build prototypes, test components and prepare final products.
Analysing and Testing Designs
Engineers perform analytical and computational tests to confirm safety, performance and regulatory compliance. This may include producing prototypes and running physical experiments. Trades personnel often conduct the hands-on testing, record real-world data and fine-tune components based on results.
Materials Selection
Engineers evaluate factors such as strength, durability and cost when choosing materials for a project. Trades teams then handle the materials and apply proper techniques to ensure products are built to the required standards and are safe for users.
Project Management
Mechanical engineers typically oversee projects from planning and scheduling to budgeting and team coordination. Trades professionals carry out day-to-day tasks, including assembly, fabrication and quality checks, to meet project milestones on time and within budget.
Thermal and Fluid Systems
Mechanical engineers design and optimise thermal and fluid systems for HVAC, automotive and other applications. Trades professionals install, service and maintain these systems, ensuring they operate correctly and remain efficient over time.
