You get to work on meaningful projects that actually help people in the world.

For example, helping people gain access to money (for people who can't open a bank account) or allowing people to easily transfer money, etc.

Developers' infrastructure is not so good. The staging environment is unreliable, CI servers are failing frequently, and setting up stages is complicated.

Development is slow due to unstable infrastructure and the fact that many people are working on the same project.

You need to put emphasis on internal infrastructure. If possible, strive to maintain as little as possible and use good external solutions as much as possible.

If there is something that needs to be maintained internally, then you need to put the best people on infrastructure, even if it means paying them much more than their colleagues.
