Blockchain Security Engineer

Join our Blockchain Security team!
Our growing team is directing the future of blockchain security. We review blockchain code and smart contracts for security vulnerabilities. Between engagements, we build custom tools like Manticore, Ethersplay, Slither, and Echidna to aid our process. Think of all of the security tools for x86 that you would have liked to have built yourself, but mature versions already existed. Few of those tools have been built yet for blockchain architectures. Join us to make a career-defining contribution.

Role Description
You will be at the forefront of blockchain security research. You will audit smart contracts, blockchain infrastructure code, and decentralized applications for security vulnerabilities using a combination of manual static analysis and our tool suite. In your time between engagements, you will help improve our existing tooling and create new tools and analytics. Other practitioners will come to rely on your work. You will make a name for yourself in this nascent discipline.
