Requirements

Candidates should have 3+ years of engineering experience, including shipping production protocols with significant TVL. Expert-level Solidity and/or Rust skills and a deep grasp of EVM/SVM internals are required. A strong understanding of gas/compute metering on Ethereum, L2s, and Solana, and how off-chain components interact with contracts is necessary. Candidates must be comfortable owning end-to-end security, including access control, upgradeability, failure-mode analysis, and incident response. Excellent communication skills and experience partnering with frontend, backend, and product teams are also essential. Bonus points for prior experience with AMMs, bridges, MEV/intents systems, consensus algorithms, ZK proofs, fast-finality research, cross-chain messaging standards, or significant open-source contributions.

Responsibilities

The Protocol Engineer will design and implement Solidity and Rust smart contracts for the Metalayer protocol across EVM, L2s, and SVM. Responsibilities include owning on-chain security, including role-based access control, pause/upgrade paths, and high-value asset protections. The role involves driving audits by specifying, coordinating, and remediating findings with security firms. Collaboration with relayer, indexer, and frontend teams to define clear, developer-friendly on-chain APIs is expected. The engineer will also build tooling for on-chain monitoring, alerting, and gas/performance profiling, and research and prototype new protocol features such as fast-finality bridges and ZK-verified proofs.
