About the Job

Security of the protocols developed at Babylon is of paramount significance, as they will serve as the backbone for an unprecedented shared economy powered by Bitcoin. We are looking for a highly experienced security professional who is paranoid about loopholes and attack vectors at all fronts in decentralized protocols to lead our effort in securing Bitcoin staking technologies we develop. This role requires independent thinking and execution, while coordinating with the research and engineering team members to achieve the security objectives.

Your main responsibilities include:

  • Be the owner of security of all technologies, protocols, and products developed by the team, including potential attack vectors in algorithms, cryptography, code, and deployments.

  • Establish overall security objectives and lead the planning and execution to achieve them

  • Identify external security researchers and work closely with them for security review and analysis

  • Coordinate with the engineering team to establish best security practices in software development cycles

  • Create product launch plans and approve feature rollout based on security considerations

About You

As an experienced security professional, you have seen enough past incidents to understand how important yet how challenging it is to secure decentralized protocols. You are paranoid about anything that might give attackers an edge, yet you are capable of translating all your security concerns into actionable countermeasures. You understand that security needs to be baked into the culture of the team and you are passionate in championing that.
