Paxos is on a mission to enable the movement of any asset, any time, in a trustworthy way. Today’s financial infrastructure is archaic, expensive, inefficient and risky - supporting a system that leaves out more people than it lets in. So we’re rebuilding it. 

As a regulated blockchain infrastructure company, we use technology to tokenize, custody, trade, and settle assets for enterprise clients like PayPal, Bank of America, and Interactive Brokers. Paxos is a top-funded blockchain company, with more than $500 million in total funding from leading investors like OakHC/FT, Founders Fund, PayPal Ventures, and Declaration Partners. Together, we empower today’s financial leaders to build a more open, trusted economy. 

As a Senior Blockchain Security Engineer, you’ll get to: 

• Own threat modeling and security assessments of new assets/tokens, blockchains, DeFi protocols, and smart contracts
• Collaborate cross functionally with engineering, product, compliance, and operations on impact of new forks, protocols, and chains
• Lead code reviews of systems that interact with the blockchain

Your experience should include:

• At least 4 years of experience in software development or information security, with at least 2 years in the blockchain space
• Experience in smart contract security, auditing, and blockchain protocols
• Experience in a variety of languages, such as Go, Python, etc.
• Strong debugging skills and/or experience in reverse engineering
• Cryptography experience and its application to distributed ledger tech

You might also have:

• Previous work experience in a high security and/or highly regulated industry
