Review and audit Rust-based Solana programs (and optionally Solidity contracts).
Identify security flaws, gas / compute inefficiencies, and logical vulnerabilities.
Write detailed reports outlining findings, risk severity, and recommended fixes.
Collaborate with protocol and backend teams to implement best security practices.
Design automated testing and fuzzing frameworks for ongoing audits.
Stay updated on the latest exploits, attack vectors, and security research in DeFi.
Requirements:
Strong knowledge of Rust and Solana programming model (accounts, PDAs, CPI, etc.).
Prior experience auditing DeFi / staking / cross-chain smart contracts.
Understanding of cryptography, access control, and blockchain security principles.
Ability to explain vulnerabilities clearly to both engineers and non-technical stakeholders.
Fluent in English; clear technical writing skills are a must.
Nice to Have:
Experience with Anchor Framework / Move / Cosmos SDK / EVM contracts.
Publications or open-source contributions related to blockchain security.
Background in formal verification or fuzzing tools.
What We Offer:
Competitive compensation in USDT / SOL (fully negotiable).
Remote-first environment with flexible hours.
Collaboration with some of the most skilled engineers in the Solana ecosystem.
The chance to shape the security standards of one of the largest staking protocols.
If you have a sharp eye for vulnerabilities and a passion for secure DeFi, we’d love to hear from you.
