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.
