Working on features that go live to a huge player base - you actually see your work in the game and can track real player feedback. Team is one of the strongest in the mobile gaming industry, genuinely experienced people around you. Good autonomy for senior devs, and the team is open to using newer Unity features when it makes sense. Compensation is competitive and reflects the level of work.
Cons
Roadmaps evolve during development, need to stay flexible with priorities.
