BUILDING SOMETHING BIG
We’re more than a payment app. We’re changing the global economy with secure, simple technology that costs less. Our passion is to make sending money as open and easy as sending anything else digitally.
NAME DROPPING
We were founded in 2013 by serial internet entrepreneurs Jeremy Allaire and Sean Neville. Some of the most impressive names in the industry believe in us (to the tune of $136 million and counting): Goldman Sachs, IDG Capital Partners, Breyer Capital, Accel Partners, General Catalyst Partners, Baidu, CICC Alpha, EverBright, WangXiang and CreditEase.
EXPANDING THE CIRCLE
We like folks who are excited about the potential of digital currency technology. Who are curious. Who are up for a challenge and want to be part of a team — and make a true difference within it.
LURING YOU IN
Like the sound of unlimited paid time off, flexible hours, paid lunches and unlimited happy hours? These unbeatable perks are the cherry on top of standard medical and dental insurance, 401K, mobile phone benefits and commuter discounts. (Let’s be honest, they’re the rainbow sprinkles, too.)

 

Julia Hausman
Compliance Analyst

Circle is flexible in every way - not just in hours and vacation time. They've also given me the confidence and support to grow and change my role so I could follow my passions over the past four years. I love getting to work with such creative, smart people.

Karla Martinez
Paralegal

Coming to Circle from a law firm was a huge change for me, but I’ve learned so much in just a few months. From learning about cryptocurrency to employment law to stock options, I love that I get to work on something new every day. I’m excited to continue working for a company that gives me an opportunity to learn something new every day.

Jon
Analytics

Circle has been an ideal place for to gain technical knowledge from pros with deep expertise in their fields. Working alongside seasoned engineers and data scientists, a younger professional can learn the ins-and-outs of complex frameworks that would take years to master elsewhere. Circle has taken my technical skills to the next level.
