Protocol Security Engineer

Чем предстоит заниматься -Break things on purpose. Threat-model and review Solidity contracts, blockchain state transition functions in Rust, and other critical systems before an attacker gets the chance. -Own protocol components. Take responsibility for the secure architecture and implementation of the components you adopt, from design review through production. -Track the adversary. Follow hacks, exploits, and new attack vectors across the industry and convert the lessons into concrete improvements in our systems. -Scale security through others. Embed secure-design practice across development teams and influence architecture decisions early, without formal authority. -Use AI on defense. Apply modern AI systems to scale security work, while accounting for attackers using the same tools. -Respond when it counts. Join security investigations and incident response, often under time pressure with incomplete information. Наши пожелания к кандидатам -A record in security engineering or security research: threat modeling, security-focused code review, or vulnerability research on production systems, with findings you can walk through mechanism by mechanism. -Proficiency in strongly typed languages such as C++, Go, or Scala. Rust and Solidity are our primary languages, and prior experience with them is not required. -Deep grounding in algorithms and data structures, including their computational and memory complexity, with experience implementing them from scratch. -Protocol-level debugging and root-cause analysis on complex distributed systems. -Working knowledge of recent security incidents in the blockchain space and the prevention techniques behind them. -Clear written and spoken English, the company's working language. -Nice to have: Hands-on experience with Solidity smart contracts, ZK circuits, or core blockchain protocols. Public security research, audit reports, bug-bounty results, or CTF history all count as evidence.
