You're a self-starter who thrives on tackling the toughest and most meaningful problems, even if they are the most difficult problems. You're comfortable with the unknown and understand that #startuplife means that you're going to be wearing multiple hats. And that's what motivates you. You're accountable and obsessed with improvement, both in yourself and in others.

  • Identify security issues related to consensus safety, chain halting, permission models flaws, block production vulnerabilities.
  • Implement and run custom scripts and test scenarios to simulate real-world validator/network behaviors, chain stress conditions, and edge cases.

Requirements
  • Strong written and spoken English communication skills.
  • High diligence and strong attention to detail, especially in multi-step testing and long-running experiments.
  • Solid understanding of blockchain architecture and node internals (e.g., Cosmos SDK / CometBFT, Go-Ethereum (Geth) internals, and Hyperledger Fabric / Besu)
  • Strong scripting & automation skills with Python or Bash
  • Familiarity with Docker and containerized testing environments.
  • Prior experience in manual Web3 security auditing is preferred, but not required.

What We Offer
  • Opportunity to shape the national conversation on blockchain and security.
  • Collaborate with industry-leading security researchers, technologists, and global institutions.
  • Flexible work environment and mission-driven culture.

Compensation: If the role is performed in the US, the target annual compensation is $120,000 - $180,000. The exact compensation at which this job is filled will be determined by the skills and experience of qualified candidates.
