About LayerZero
LayerZero helps developers build applications that communicate across blockchains through omnichain messaging infrastructure. Using immutable smart contracts deployed on each supported chain, the protocol sends and receives messages between networks with censorship-resistant delivery. Developers can configure security through Decentralized Verifier Networks and independent Executors, supporting cross-chain state transitions, token transfers, and composable application logic across EVM and non-EVM chains.
Skills
Candidate Availability
Required and preferred rules are kept separate and reflect the wording in the original posting.
About the Role
You will design, implement, and maintain core protocol components that enable secure cross-chain messaging and interoperability. You will write high-assurance smart contract code, build and verify proofs and validators, and optimize for gas and performance. You will own components through architecture, testing, deployment, and iteration, and apply formal verification, fuzzing, and simulation to improve protocol robustness.
Requirements
- Bachelor's degree in Computer Science or equivalent practical experience
- Strong smart contract development experience in Solidity or equivalent languages
- Experience building protocol-level infrastructure such as bridges, interoperability layers, state sync systems, or light clients
- Ability to write clear, well-tested, and secure code with strong security and upgradeability practices
- Familiarity with distributed systems fundamentals and adversarial blockchain conditions
- Experience working with workflow engines
- Previous experience with blockchain technologies, smart contracts, or decentralized finance is a plus
Responsibilities
- Design and implement core protocol contracts and logic on EVM and non-EVM chains
- Develop and validate message validators, data availability mechanisms, and proof verification
- Collaborate with other teams to develop new system primitives and validate security assumptions
- Own components across architecture, implementation, testing, deployment, and iteration
- Apply formal verification, invariant testing, simulation frameworks, and fuzzing
- Investigate cryptographic techniques to enhance trust minimization and scalability
- Optimize contracts for correctness, safety, gas efficiency, upgradeability, and modularity
