What you’ll be responsible for:

In 2020, Circle unveiled Circle APIs: a set of solutions and smarter technology to help businesses accept payments in a more global, scalable and efficient alternative to traditional banking rails (spoiler: we’re using USD Coin under the hood).

• Provide security guidance to various organizations throughout the company.
• Support broader security team projects such as threat modeling, vulnerability scanning, audits, and custom tool building.

• Ability to manage multiple competing priorities and use good judgment to establish order of priorities on the fly.
• Self-motivated and creative problem-solver able to work independently with minimal guidance.
• Experience/familiarity with Slack, Apple MacOS and GSuite.
