📋 Description

• Design & implement Solidity and Rust smart contracts across EVM, L2s, and SVM that form the core Metalayer protocol. • Own on-chain security—role-based access control, pause/upgrade paths, and high-value asset protections. • Drive audits: spec, coordinate, and remediate findings with top security firms. • Collaborate with relayer, indexer, and frontend teams to define clear, developer-friendly on-chain APIs. • Build tooling for on-chain monitoring, alerting, and gas/performance profiling. • Research & prototype new protocol features that expand Metalayer’s surface area.

🎯 Requirements

• 3+ years engineering experience, including shipping production protocols with significant TVL. • Expert-level Solidity and/or Rust skills and a deep grasp of EVM/SVM internals. • Understand gas/compute metering on Ethereum, L2s, and Solana, and how off-chain components (relayers, indexers) interact with contracts. • Comfortable owning end-to-end security: access control, upgradeability, failure-mode analysis, and incident response. • Excel at systematic debugging, test-driven development, and writing clean, well-reviewed code. • Communicate clearly and enjoy partnering with frontend, backend, and product teams. • Bonus points for prior experience building AMMs, bridges, or MEV/intents systems. • Hands-on work with consensus algorithms. • Familiarity with ZK proofs, fast-finality research, or cross-chain messaging standards. • Significant open-source contributions to blockchain clients, protocol libraries, or security tools.
