LayerZero
The Future is Omnichain.
Founded in 2021, LayerZero’s vision is to create a community of cross-chain developers, building dApps that are no longer constrained by individual blockchain capabilities. With LayerZero's simple, generic messaging protocol, builders will develop cross-chain dApps designed to unify the power of individual blockchains.
We are funded by the best investors in the world including:
a16z, Sequoia, PayPal, Binance Ventures, Coinbase Ventures, Uniswap Labs, Circle Ventures, Delphi Digital, and many more.
ABOUT THE ROLE
LayerZero Labs is a research-driven protocol company building the infrastructure for cross-chain interoperability. We are looking for a Cryptographer to join our research team and contribute to the design, analysis, and implementation of cryptographic protocols at the core of our systems.
This is a full-time role based in Vancouver, BC. We provide relocation assistance and visa/immigration support for candidates requiring it.
WHAT YOU'LL DO
- Design and analyze cryptographic protocols with a focus on zero-knowledge proof systems (SNARKs/STARKs), proof aggregation, and recursive composition
- Contribute to applied research translating theoretical constructions into production-grade implementations
- Evaluate cryptographic assumptions and assess security of existing and proposed primitives
- Collaborate with low-level systems engineers on performance-critical implementations in Rust/C++
ABOUT YOU
- PhD (or equivalent research experience) in Cryptography, Mathematics, or Computer Science
- Deep expertise in the design and/or cryptanalysis of zero-knowledge proof systems or lattice-based schemes, including their related primitives
- Strong publication record or demonstrable open-source research contributions
- Comfort working at the intersection of theory and engineering — you can write a security proof, implement a cryptographic primitive, and benchmark code
- Experience with Rust or C++ is a strong plus
- Background in distributed computing or GPU development is a plus

ABOUT THE ROLE
We’re seeking a Systems Engineer to join LayerZero. In this role, you’ll build the foundational systems that power our execution and infrastructure layers, including Zero.
This is a low-level, performance-critical role focused on runtime architecture, concurrency, and scalable execution. You will make architectural decisions that directly impact how our systems execute, scale, and remain stable under load.
WHAT YOU'LL DO
- Architect high-performance systems and leverage AI to implement them in Rust.
- Build and optimize core runtime, networking, or state management components.
- Profile and improve performance both at low-level (CPU, memory) and cluster-scale (network, scheduling).
- Debug race conditions, deadlocks, and production performance issues.
- Contribute to architectural decisions around scheduling, synchronization, and system scalability.
- Own systems end-to-end from design through production.
ABOUT YOU
- Bachelor’s degree in Computer Science, Computer Engineering, or equivalent practical experience.
- 2+ years of experience building systems-level or performance-critical software.
- Strong proficiency in systems programming and leveraging AI to build software.
- Deep understanding of concurrency, CPU architecture, cache hierarchy, and operating systems .
- Experience designing or contributing to low-level storage, compute, or network infrastructure.
- Strong intuition for striking a pragmatic balance between complexity for performance and simplicity for robustness
- Experience using low-level profiling and debugging tools in production environments.
- Interest in working on distributed and execution-layer systems.

ABOUT THE ROLE
As 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.
WHAT YOU'LL DO
- Design and implement core protocol contracts and logic on both EVM and non-EVM chains (e.g., message validators, data availability mechanisms, proof verification).
- Collaborate with various teams to develop new system primitives, validate security assumptions, and improve protocol robustness.
- Own components across their lifecycle: architecture, implementation, testing, deployment, and iteration.
- Contribute to high-assurance engineering practices: formal verification, invariant testing, simulation frameworks, fuzzing, and audit readiness.
- Investigate emerging cryptographic techniques and novel designs to enhance trust minimization and scalability.
- Optimize for correctness and safety in gas-constrained environments, with an emphasis on upgradeability, modularity, and composability.
- Keep pace with changes across LayerZero-supported chains to ensure cross-chain compatibility and performance.
ABOUT YOU
- Bachelor's degree in Computer Science or related field, or equivalent practical experience.
- Strong smart contract development experience in Solidity or equivalent languages, with a focus on correctness, modularity, and gas efficiency.
- Have built protocol-level infrastructure: bridges, interoperability layers, state sync systems, light clients, or equivalent.
- Write clear, well-tested, and secure code and have strong opinions on security models and upgradeability patterns.
- Familiar with distributed systems fundamentals and have good intuition around adversarial conditions in blockchain environments.
- Experience working with workflow engines.
- Previous experience with blockchain technologies, smart contracts, and decentralized finance is a strong plus.
The 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.
