At Circle, we're shaking up the global economy by making money simple. With us, you can send money like a text — instant, secure and free — whether your friend is across the table or across the ocean. How exactly are we doing this? Unlike existing systems that are closed and proprietary, we use open internet standards and protocols, including the blockchain (allowing us to offer this service for free). Our mission is to connect every person in the world by exchanging value across borders, between currencies and among friends.

• Collaborate with a fun, passionate team to help craft solutions to problems using the latest technologies
• Learn more about Circle’s business domains while teaching others about development and design
