Experience working on high-throughput, low-latency systems, trading infrastructure, cryptography, or custody platforms is a strong plus

Our take

Paxos develops regulation-compliant infrastructure services for companies looking to add features like crypto brokerages or branded stablecoins to their customer offerings. Its focus on regulatory compliance, and its status as one of only three national trusts born in the crypto ecosystem, gives it an edge in building a unique and global network of enterprise customers.

Cryptocurrency remains a risky sector, so a company at the forefront of crypto regulation is proving highly attractive to a growing sector of enterprises tentatively dipping their toes in. It is pushing ahead of competitors as one of the largest crypto/blockchain startups with substantial funding and an impressive valuation.

Its growth has been backed up by material results, too. It has established relationships with firms like Bank of America, Credit Suisse and Mastercard. PayPal also leverages Paxos on its backend to enable its users to buy, sell and hold crypto. This proven success with an expanding roster of big-name clients is very impressive, as is the company's success in receiving approval to convert to an OCC National Trust Bank.
