LayerZero Labs - Cryptographer

• 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++ • 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
