Decent place, but work-life balance is a struggle.
Johnson Controls is a huge company with some good people, but man, the hours can be tough. Especially as a Field Service Engineer, I felt like I was always on call.
They offer good benefits, which is nice for a big corporate company like JCI. You get to work on cool HVAC systems and learn a lot about industrial solutions. There's job stability here, which isn't always a given in the industry.
Work-life balance as a Field Service Engineer is really hard to maintain. I often worked 50-60 hour weeks, including weekends. Being on call for building automation issues means you can't really switch off.
Management needs to seriously look at staffing levels for Field Service Engineers. Implement clearer policies around on-call rotation and compensation for extra hours to improve work-life balance.
