Pros
Lots of pros when compared to other companies I have worked at. Culture wise there is no place like KeyPay. Everyone gets along. That is one of the biggest strengths of the team. Management aren't breathing down your neck or actively taking over. They are extremely easy-going and approachable.
Dev-wise, the approach can be summed up as pragmatic and the structure is fairly flat. The decisions of the team are discussed together for short amounts of time before a sensible decision is made. There are no 2 hour meetings to discuss what can be discussed in 10 minutes. Sometimes we decide to add 2 more weeks of dev time... sometimes 4 more weeks of dev time. In either case, there is rarely a need to rush your work. You aren't expected to implement the SOLID principles to a tee in every part of your work. You won't be whipped for not following a Red-Green-Refactor TDD approach. You aren't expected to know everything. Asking questions is encouraged and trying to be a 10x engineer/rockstar dev is discouraged. On the other hand, the team do expect a certain level of ability and clean code. There are code reviews but these aren't as thorough and in-depth as I have experienced in other jobs which is quite refreshing.
If these sound like cons to you then I'm glad we don't work together :)
Cons
I can't think of any cons. The only one that comes close, is that remote work isn't for everyone, but for me and my current personal life situation its perfect. Depending on location, there are offices/share spaces where some colleagues work if that is more for you.
