Cryptographer

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
