Circle is a financial technology company at the epicenter of the emerging internet of money, where value can finally travel like other digital data — globally, nearly instantly and less expensively than legacy settlement systems. This ground-breaking new internet layer opens up previously unimaginable possibilities for payments, commerce and markets that can help raise global economic prosperity and enhance inclusion. Our infrastructure – including USDC, a blockchain-based dollar – helps businesses, institutions and developers harness these breakthroughs and capitalize on this major turning point in the evolution of money and technology.

  • Proven experience in Golang and related technologies
  • Expertise with cryptography, blockchain technologies, and the underlying fundamentals and mathematics.
  • Technical understanding of blockchain technologies including but not limited to BIPs, UTXO, EVM, Nakamoto Consensus, and cryptography.
  • Willingness to pick up new and emerging ground-breaking blockchain technologies
  • Excellent communication skills, able to collaborate with remote teams, share ideas, and present concepts optimally.
  • Extensive knowledge of secure cryptosystem operating practices is required.

We also prefer but don’t require:

  • Advanced degree or equivalent experience in cryptography, computer science, mathematics, or related fields is strongly preferred.
  • Experience participating or maintaining in open-source software development is highly preferred.
