With LayerZero's simple, generic messaging protocol, builders will develop cross-chain dApps designed to unify the power of individual blockchains.\nWe are funded by the best investors in the world including:\na16z, Sequoia, PayPal, Binance Ventures, Coinbase Ventures, Uniswap Labs, Circle Ventures, Delphi Digital, and many more.\nABOUT THE ROLE\nAs a Protocol Engineer, you'll work on the core infrastructure that underpins decentralized interoperability. You will design and implement core protocol components that operate across heterogeneous chains with rigorous security and performance constraints. You’ll be part of a deeply technical team working across LayerZero’s protocol and smart contract surface, contributing to novel cross-chain primitives and helping shape the architecture of systems used by some of the most demanding applications in Web3.\nWHAT YOU'LL DO\nDesign and implement core protocol contracts and logic on both EVM and non-EVM chains (e.g., message validators, data availability mechanisms, proof verification).\nCollaborate with various teams to develop new system primitives, validate security assumptions, and improve protocol robustness.\nOwn components across their lifecycle: architecture, implementation, testing, deployment, and iteration.\nContribute to high-assurance engineering practices: formal verification, invariant testing, simulation frameworks, fuzzing, and audit readiness.\nInvestigate emerging cryptographic techniques and novel designs to enhance trust minimization and scalability.\nOptimize for correctness and safety in gas-constrained environments, with an emphasis on upgradeability, modularity, and composability.\nKeep pace with changes across LayerZero-supported chains to ensure cross-chain compatibility and performance.\nABOUT YOU \nBachelor's degree in Computer Science or related field, or equivalent practical experience.\nStrong smart contract development experience in Solidity or equivalent languages, with a focus on correctness, modularity, and gas efficiency.\nHave built protocol-level infrastructure: bridges, interoperability layers, state sync systems, light clients, or equivalent.\nWrite clear, well-tested, and secure code and have strong opinions on security models and upgradeability patterns.\nFamiliar with distributed systems fundamentals and have good intuition around adversarial conditions in blockchain environments.\nExperience working with workflow engines.\nPrevious experience with blockchain technologies, smart contracts, and decentralized finance is a strong plus.\nThe base salary for this position ranges from $120,000/year up to $250,000/year. Salary is based on a number of factors and may vary depending on job-related knowledge, skills, and experience. LayerZero is a total compensation company. Dependent on the position offered, equity, and other forms of compensation may be provided as part of a total compensation package, in addition to a full range of medical, financial, and/or other benefits.\nEqual Opportunity Employer\nLayerZero Labs is committed to fostering a diverse and inclusive workplace.
