Blockchain Security Lead

ABOUT THE ROLE When Mintlayer reaches institutional scale, the security of the protocol will be what allows sovereign wealth funds and regulated asset managers to trust it with real capital. The Blockchain Security Lead builds and maintains that trust from the inside: internal audits, external audit firms, the bug bounty program, and the security standards every major release must meet. We are looking for someone who has published CVEs, audited Rust-based blockchain code, and understands that finding a critical vulnerability before an attacker does is one of the most valuable contributions an engineer can make.
