Pros
Satisfying job when dealing with customers in your region every day. If you like the freedom of field service, this has it. A lot of times you get to make your own schedule, and coordinate service for your customers. This job keeps you sharp, you learn something new every day and it will prepare you for any type of field service job. It doesn't get much harder or technical than here.
Cons
Below average base pay. Out of the three field service jobs I have had, this one was by far the most technical and hard work, the dirtiest environment, and the least amount of pay. The President of Amada America was quoted as saying no Field service engineer was worth 50k a year salary. This is absurd, FE's put in long hours of driving and labor every day, installing millions in machinery each year. Some of them have been in the field over 10 years, with no ladder to climb and no structured raises.
