United States4mo ago

In Office NA Banking Cryptocurrency Security Engineer Rust EVM Ethereum Solidity Foundry

Requirements

• Fluency in reading and writing production-level code in systems languages with a strong preference for Rust. • Deep expertise in EVM internals including knowledge of opcodes, storage slots, gas metering, and precompiles. • Proven track record of offensive security such as high rankings in CTFs or submissions to bug bounty programs with a focus on finding vulnerabilities that could lead to economic exploits (e.g., MEV). • Experience building custom security automation tooling rather than relying solely on standard scanners, indicating the ability to develop and implement unique solutions for complex problems in blockchain infrastructure. • Knowledge of recent hacks and mitigation strategies as they relate to Ethereum or similar blockchains where Solidity is used (implied by expertise required).

Responsibilities

• Proactively hunt for vulnerabilities in the Tempo protocol, consensus engine, and bridge architecture, treating our mainnet like a continuous CTF challenge. • Design and implement security tooling and automation in liaison with the Foundry team to catch logic errors and edge cases. • Partner with engineering teams to review critical architecture across our codebase. • Analyze incentives and game-theoretic risks within the protocol, such as MEV and staking dynamics, to prevent economic exploits.
