Je travaille chez Square à plein temps
Engineering teams at Square have been given the opportunity and the freedom to operate largely independently. There is a strong engineering culture here with great engineering practices and lots of meetups (both internal and external). On top of all these, the payment industry offers a lot of complex business challenges and we are allowed to use cutting edge technologies such as Tensorflow or Dataflow.
Square is at a weird spot: not a huge company with super deep pockets but not a startup either. So we are showing pain that's related to our size.
The Payment industry is strongly linked with both domestic and global economies. The competition is fierce, too.
