Lagrange Labs is looking to hire a Cryptography Engineer to join our fast
growing research team. The ideal candidate would have familiarity developing
production level zero-knowledge proof systems in Rust.
Our team (<https://www.lagrange.dev/>) is currently building ZK MapReduce, a
novel proof system that is designed for concurrently proving large-scale batch
storage inclusion and dynamic MapReduce style computations. At the core of the
ZK MapReduce stack is Recproofs, a new vector commitment scheme developed by
the Lagrange Labs research team.
Recproofs are optimized for onchain applications that require computing and
efficiently maintain a proof over a moving stream of blocks. Each proof can be
updated in logarithmic time whenever the leaves in a subset change or the
overall set changes.
Our proofs are already being used to empower new applications ranging from
trustless DeFi primitives computed from historical data, to digest
transformations for ZK-rollups to verifiable public goods funding based on
onchain activity.
### Experience:
The ideal candidate for the cryptography engineering role at Lagrange would
have:
* A background in implementing applied cryptographic primitives in Rust (zero-knowledge proofs, elliptic curve cryptography, vector commitments, etc).
* Experience working with modern Rust based proving systems (Plonky2, Nova, Halo2, Bellman, etc).
* An strong understanding of the theoretical basis of zero-knowledge proofs
* An interest in working on low-level optimizations to novel proof constructions and distributed proving systems.
* Experience in writing and maintaining cryptographic libraries in Rust
* Strong written and verbal communications skills
* Independent motivation and an interest in being part of a team building innovative products
### Why work with us?
* Opportunity to work alongside other passionate researchers and engineers
* Competitive salary + equity package
* Respectful team culture with high individual ownership of your work
* Ability to contribute to high impact research publications
* Team offsites and conference travel
* Fully remote with flexible hours
* Unlimited vacation policy
* Top-tier health coverage for US employees
