Mechanical engineer job profile

What does a mechanical engineer do?

Mechanical engineering involves the design, development and operation of machines and systems. It is one of the broadest engineering disciplines as it involves anything with moving parts. As a mechanical engineer, you can work across all stages of product development, from research and design to installation and commissioning.

Many industries rely on mechanical engineers, including:

• Aerospace – A mechanical engineering career in the aerospace sector involves the design, construction and maintenance of aircraft and spacecraft.
• Construction – Design the systems in buildings such as heating, air conditioning and smoke ventilation.
• Electronics – Design and develop electronics used in everything from mobile phones and computers to laboratories and research equipment.
• Food processing – Improve efficiency and process across food production lines, explore chemical interactions with food and develop new processing techniques.
• Medical – Develop, test and maintain medical equipment from simple devices to the latest technology. 
• Power – Mechanical engineers work on the generation and delivery of energy, from nuclear power plants to solar panels.
• Vehicles – Specialise in the mechanical systems that control vehicles. Automotive engineers work with cars, motorbikes and trucks, while naval architecture engineers work on oil rigs and ships. 

Duties of a mechanical engineer 

A mechanical engineer’s responsibilities vary depending on where you work and your specialism. These are likely to include:

• Using computer-aided design to create technical plans
• Applying mathematical and materials science principles to design and modify equipment
• Designing and testing mechanical components 
• Surveying systems and machines
• Producing technical documents 
• Presenting data to managers and clients
• Liaising with suppliers

More senior mechanical engineers may also:

• Manage a team of engineers
• Control budgets and project plans

Working environment and hours

Where do mechanical engineers work? 

Mechanical engineers can work in offices, laboratories, workshops, factories, oil rigs, research facilities and building sites. As a result, an engineer’s dress code can range from business attire to a hard hat on a construction site. Travel during the working day is common as you may need to visit client sites or suppliers. 

Hours

The working hours for mechanical engineers are usually full-time (37 to 40 hours a week), Monday to Friday. Depending on your role you may work shifts over weekends and evenings. 

Skills required to become a mechanical engineer

A mechanical engineering job description might include some or all of the following skills:

Qualifications and training 

To study mechanical engineering at university you will need to achieve good grades in three or four A Level subjects, including Maths and at least one science. Relevant A Levels to choose include:

• A Level Chemistry
• A Level Physics
• A Level Mathematics
• A Level Further Mathematics

If you did not study A Levels you will need to study an Engineering Foundation.

To qualify as an engineer, you should study an undergraduate degree (BEng) in engineering, which is usually three years. Choose a subject like mechanical, electromechanical, mechatronics or mechanical/manufacturing engineering. 

Alternatively, study a Master of Engineering (MEng) for four or five years, which combines the foundations of a BEng and further specialist knowledge. This level of education gives you the opportunity to apply for Chartered Engineer status. 

Degrees should be accredited by the Institution of Mechanical Engineers or Institution of Engineering and Technology. 

The ability to speak another language can also be helpful as many employers operate internationally with clients around the world. 

Work experience 

Work experience is a great way to demonstrate to future employers that you are passionate about your chosen career. It will deepen your knowledge and help you find out what the role involves. Many degrees include work placements, and university careers services can support students who want to arrange their own.
