About CloudWalk:
We are one of the fastest growing fintechs on the planet. We kick ass. A unicorn, with millions of happy customers, a hardcore team, and hundreds of millions in funding and revenue. But not your typical startup.

  • Communication skills. You should be able to communicate effectively with multiple teams.
  • Ability to communicate and debate in English and Portuguese.

Nice-to-have skills:

  • Experience with financial or payment industry.
