  • Shepherd external security audits with the help of leading third-party audit firms.

  • Operate bug bounty programs on Immunefi, including leading, monitoring, and triaging submissions.

  • Work in a diverse, decentralized team environment with web3 professionals.

  • Clearly communicate security risks, findings, and proposed solutions.

  • Adhere to the highest standards of integrity, trust, and professionalism.

Requirements:

  • Strong desire to understand how things work, with the ability to quickly absorb new information.

  • Prior experience with code reviews, reverse engineering, fuzzing and/or binary exploitation.

  • Willingness and aptitude to learn different web3 technology stacks written in Rust, Golang or C.

  • Prior high ranking on bug bounty leaderboards, code audit contests, or CTF competitions. [Nice to have]
