The short version: A field service engineer installs, starts up, repairs, and maintains complex equipment at customer sites. Instead of working at one desk or plant, they travel to factories, hospitals, data centers, labs, and power plants wherever their company’s machines are. The job mixes hands-on troubleshooting with customer service, and it usually comes with a lot of travel.
Field service roles are some of the hardest openings our manufacturing and automation clients fill, mostly because of the travel. Here is what the job really looks like.
What does a field service engineer do?
- Install and commission new equipment at customer sites
- Troubleshoot breakdowns, often under pressure because a line or system is down
- Perform scheduled maintenance, calibration, and software or firmware updates
- Train customer operators and maintenance staff
- Write service reports and feed problems back to design and quality teams
- Spot upgrade and service contract opportunities for the sales team
Industries that hire field service engineers
| Industry | Equipment they service |
|---|---|
| Industrial automation | Robots, PLC-controlled machines, packaging lines |
| Semiconductors | Wafer fab tools and cleanroom equipment |
| Medical devices | Imaging systems, lab analyzers, surgical equipment |
| Energy and power | Turbines, generators, switchgear, battery storage |
| Data centers | UPS systems, cooling units, power distribution |
| HVAC and building systems | Chillers, controls, large commercial units |
How much travel is involved?
Travel is the biggest factor in this job. Some regional roles cover a territory and get you home most nights. National and international roles can mean weeks on the road, overnight flights, and weekend call-outs when a customer’s equipment fails. Job posts often list travel from 25 percent to 75 percent or more. Ask exactly how many nights away per month before you accept an offer.
The travel often comes with perks: per diem, a company vehicle or rental cars, airline and hotel points, and overtime or travel pay. Many engineers use a few years in field service to see many plants and industries quickly.
Skills employers look for
- Troubleshooting. Reading schematics and finding faults across mechanical, electrical, and software systems.
- Controls knowledge. PLCs, HMIs, drives, and sensors come up in most industrial roles. See what a controls engineer does.
- Customer skills. Calm communication with frustrated customers whose equipment is down.
- Safety. Lockout/tagout, electrical safety, and site safety rules.
- Independence. You are often the only person from your company on site.
Education and background
Many field service engineers have a bachelor’s in mechanical, electrical, or mechatronics engineering. Others come up through an associate degree in electronics or engineering technology, or from military technical roles. Employers usually care more about troubleshooting experience than the exact degree. See our guides to electrical engineering careers and mechanical engineering careers, or the full list of types of engineering.
Career path
Field service is a strong launch pad. Common next steps include senior or lead field service engineer, field service manager, applications engineer, sales engineer, and controls or commissioning engineer. Engineers who know a product inside out from fixing it in the field are valuable in design and quality roles too. Robotics and automation companies in particular promote from their field teams.

How much do field service engineers make?
BLS does not track field service engineer as a separate job, and pay depends heavily on industry and travel. Semiconductor, medical imaging, and power generation roles tend to pay the most, and overtime and travel pay can add a lot on top of base salary.

Frequently asked questions
Is field service engineer a good job?
It is a good job for people who like travel, variety, and hands-on problem solving. The travel can be hard on family life, so it fits some career stages better than others.
What is the difference between a field service engineer and a field service technician?
Engineers usually handle more complex installs, commissioning, and root cause work, and often have an engineering degree. Technicians focus on routine maintenance and repairs.
Do field service engineers need a license?
Usually not. Some roles require electrical safety training, manufacturer certifications, or a clean driving record.
