Senior Software Engineer

Engineering at Circle:

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).

In 2021, Circle launched Circle Yield, Circle Account, and Verite to help our users earn, manage, and secure their funds. We built foundational industry partnerships which grew USDC market cap by 10x+. To broaden the utility of USDC, we also added support for digital dollars on 6 new blockchains: SOL, XLM, HBAR, TRX, AVAX, FLOW.

Over the next year, we will continue to grow USD Coin and the Circle API platform to become the #1 US dollar stablecoin of the world by building, scaling and partnering with both web2 and web3 ecosystems. Expect to see product announcements and launches for L1, L2, DEFI, and Identity solutions!
