what is a maintenance engineer?

As a maintenance engineer, you apply engineering concepts to ensure the smooth running of industrial machinery and equipment. Some of the activities you perform include installing, repairing and maintaining different types of equipment. Maintenance engineers monitor and diagnose machine failures using specialised equipment. In case of breakdowns, you restore the faulty equipment and ensure optimal performance.

Maintenance engineers use their specialised training for strategic problem-solving and guiding technicians to repair problems in the system. Depending on your employer and the company's size, you are likely to participate in significant installations and the maintenance of critical machinery only. The rest of the time, you take on managerial tasks. However, you are expected to do hands-on work in some companies, like performing generalised repairs and maintenance activities.

A career as a maintenance engineer allows you to work in mechanical repair workshops or companies dealing with machinery and equipment maintenance. Aside from working for consultancy companies, you can work in-house at large factories or manufacturing plants in various industries, including automotive, oil and gas, and electronic businesses.

how to increase your salary as a maintenance engineer

As a maintenance engineer, your earnings increase with experience and expertise. When you have a few years of experience in maintenance roles, you receive a higher salary due to the knowledge and expertise you bring to the company. Your educational qualifications improve your earning potential, too.

The size of the company you work for also influences your earnings. When you work for a small company, you earn less compared to maintenance engineers working for larger companies. In a large company, you handle complex duties. Besides, the vast resources of large organisations increase your earnings.

maintenance engineer skills and education

Some of the requirements of becoming a maintenance engineer include:

  • Education: pursue a bachelor's degree in engineering, such as mechanical, manufacturing or electrical engineering. These engineering courses equip you with technical knowledge of how machines operate and maintenance routines. Look out for professional development opportunities by joining the Hellenic Association of Mechanical and Electrical Engineers.
  • Work experience: enrol for internships and apprenticeships to improve your maintenance skills and knowledge. Some maintenance specialisations require licensing. For instance, you cannot maintain electrical and mechanical equipment without a licence from the Technical Chamber of Greece (TEE). For aircraft mechanical engineers, you require a licence from the Hellenic Civil Aviation Authority (HCAA) under EASA regulations.

competencies and characteristics of maintenance engineers

While you need experience and knowledge of machines in maintenance engineering, soft skills also improve your job success. Some of the skills include:

  • Leadership skills: as a maintenance engineer, you are in charge of a technical team, and leadership skills will help you integrate with other staff. Motivating team members and bringing them together to accomplish a task is useful during equipment failure. With your leadership skills, you can also manage stress levels during unfavourable conditions and promote accountability for mistakes made during inspection.
  • Problem-solving skills: multiple problems arise when operating equipment and machines. Despite creating procedures for dealing with problems, you cannot exhaust all possible system failure scenarios. You need creative problem-solving skills to tackle issues outside the standard maintenance procedures.
  • Attention to detail: becoming a good maintenance engineer depends on your ability to pay attention to small details. An error or miscalculation can have serious consequences; hence, you should be keen when diagnosing equipment faults.
  • Aptitude for physics: to learn how machines and equipment work, you need a knack for maths and physics. Sometimes, complex calculations are required to identify faults in a system. Aptitude for physics will also help you understand the schematics of machines from their blueprints and plan to fix the problems.
