What is a Field Service Engineer?

A field service engineer, also known as a field engineer, is responsible for the maintenance, installation and repair of a wide variety of machinery, systems and equipment. They use their theoretical understanding of engineering concepts along with practical design and repair skills to solve problems in locations that range from airports to warehouses and building sites.

Whilst some engineering jobs require work in an office, lab or workshop most of the time, a field service engineer goes out in the field they work in and visits a range of different sites to implement their skills. It’s a brilliant role if you’re an engineer who enjoys visiting new places and working with a range of people, along with getting the chance to use your skills in hands-on tasks alongside more theoretical problem-solving.

In this article, we cover some of the key responsibilities of a field service engineer, common roles within the discipline, and what kind of skills are required to succeed in field service engineer jobs.

Key Skills for a Field Service Engineer

Technical Maintenance

The most important skill you can have as a field service engineer is the ability to service and repair a variety of different machinery and equipment. No matter what industry you work in, you’ll need good background knowledge and understanding of the kind of systems that you are working with and the technical ability to be able to identify any problems and know how to repair them.

These technical skills will be acquired through work experience, which is why many field service engineers begin as technicians or operators in their field. 


Whilst the maintenance and routine servicing of machinery is a key part of a field service engineer’s job, troubleshooting any issues or problems that arise with the machinery also a significant part. You will need to be able to interpret the results of tests and system checks, understand what happens when common problems occur, and be able to identify the most efficient solution to any system, process or component problems.

Critical Thinking

Critical thinking is a skill that is required for the same reason that good troubleshooting skills are required as a field service engineer. You will need to be able to quickly diagnose any problems that you come across in your work and identify what the best solutions are. These skills are essential if you want to work efficiently. 

Written Communication

A key part of a field service engineer’s role is writing up reports and reviews of the tests and repair work that you do. If you belong to an external company and have been brought in for routine checks or to fix a specific problem, you will need to provide the owner or operator of the machinery with a report that summarises what you have done and what may need to be avoided in the future.

You may also need to produce written reports that reflect on the work you have been doing and suggest improvements for the machinery that you commonly repair. Good written and verbal communication skills are essential to conveying this information clearly and concisely, and are a key part of being a successful field service engineer. 

Attention to Detail

A lot of the time as a field service engineer, you will find that the thing causing a problem or delay that you are there to fix is very small. You will need good attention to detail if you want to quickly be able to diagnose problems with machinery or equipment and understand what needs to be done to fix them. 


When you are a field service engineer, most of the time you will be working by yourself or as part of a small group. You will need to quickly decide what needs to be done when you arrive at a location or are working on a maintenance or repair project and break down the work into individual tasks that you can complete efficiently.

Whether you are studying manufacturing guidelines, deciding what tasks need to be completed, or writing up reports after running routine checks, organisation is a vital part of a field service engineer’s role.


Finally, field service engineer jobs are usually solitary. Most field engineers spend a lot of their time travelling around to different locations in order to complete their work. Therefore, you will need to be a very independent worker and feel comfortable managing your own time and workload in these kinds of roles.
