An Insider's view of Circle

What’s the vibe like in the office?

We have a team-oriented, open concept, collaborative office. I love working with people who are incredibly passionate about what they do.

Rachel

Office Experience Coordinator

How do you collaborate with other teams in the company?

If I can, I walk over to them, but I typically message them on Slack about an idea or contextualized piece of customer feedback. With that info, we can better understand how to enhance overall customer experience and how we can improve it.

George

Customer Experience Specialist

How has your career grown since starting at the company?

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.

Karla

Paralegal

What's the biggest problem your team is solving?

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.
