Principal Software Engineer

Circle is a global financial technology firm that enables businesses of all sizes to harness the power of digital currency and public blockchains for payments, commerce and financial applications worldwide. Circle platforms and products provide a suite of internet-native financial services for payments, treasury infrastructure and capital formation. Circle is also a principal developer of USD Coin (USDC), which has become the fastest growing dollar digital currency in the world. USDC has grown to over 43+ billion in circulation and supported over $1.9+ trillion in transactions in the past year. Circle’s payments and treasury infrastructure services available through the Circle Account and APIs helps bridge the legacy financial system and digital currency and blockchain based finance. Combined, Circle’s suite of services helps companies to participate in a more open, global and inclusive financial system.

What you’ll be part of:

With the mission “To raise global economic prosperity through the frictionless exchange of financial value,” Circle was founded on the belief that the internet, blockchains and digital currency will rewire the global economic system, creating a fundamentally more open, inclusive, efficient and integrated world economy. We envision a global economy where people and businesses everywhere can more freely connect and transact with each other with new technologies for digital money and internet-native finance. We believe such a system can raise prosperity for people and companies everywhere. Our mission is powered by the values we espouse and which we expect all Circlers to respect. We are Multistakeholder, serving the needs of our customers, our shareholders, our employees and families, our local communities and our world. Furthermore, we are also Mindful, Driven by Excellence, and High Integrity.

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!
