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.

What we look for

Each of these is a demonstrated capability, shown through work you have done:

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.
