I'm a senior-level software engineer, previously worked at tech companies, and this job is relatively easy for me. No on-call, work-life balance is good. I usually get everything done within 2-week sprints.
Cons
GMF is the true definition of work hard, not smart. There are so many dumb engineers. There was a time I had to work with non-technical teams like prod support, and it was quite frustrating. They wanted my team to build an automation so they didn't have to work manually as if anything is possible and there is no limitation within the company. I didn't even create a backlog item as it was a waste of time.
