zk-SNARK Jobs

Here at Volume, we work with the best partners to make decentralized finance protocols valuable. We solve problems of protocol utility, governance, and growth for the leading DeFi protocols. From our team effort, we are able to drive massive growth of user transactions and the launch of the protocol economy. If a protocol fails to attract user activity, token value falters and innovation will flow away from the network.
Volume delivers software tools and user experiences that increase protocol token utility and community engagement, measured by protocol transaction volume growth. The Volume team’s interests are the protocol interests: Growth of user transactions.
Volume's investors include Alameda Ventures, Curve, Solana, SimplyVC, and many others.
We are always looking for individuals who desire a high-impact, high-visibility role within a company that is making crypto and decentralized protocols valuable.
As a Sr. Cryptography Engineer on our Engineering team, you will work with us to design, evaluate, and implement zero-knowledge proof constructions, distributed cryptographic protocols, distributed key generation, as well as cryptographic protocols such as elliptic curves and hash functions. Working as an integral member of our Engineering team, you will put this cryptography into practice for privacy and scalability.
As our Sr. Cryptography Engineer, you will have a chance to work across the full spectrum of our protocol architecture that is built around the Cosmos-SDK, built in Golang, Rust and Solidity. Our software empowers Sommelier validators to secure the Sommelier network which offers financial automation globally. As an early employee you will be a critical part of our core team and have a significant influence over the direction of the company.
Responsibilities:

• Evaluate and analyze existing zkSNARK and zkSTARK proof systems such as Groth '16, Ben-Sasson '18, and PLONK for security, expressivity, and performance while also monitoring the state of the research field for compelling new theoretical advances
• Update and alter existing cryptographic protocols, customizing them for specific proof-of-concept and production use-cases
• Produce technical specifications for designs and instances of cryptographic protocols and assist with implementation
• Implement, review, and test cryptographic operations and protocols, primarily in Rust
• Evaluate existing implementations
• Bring DeFi to reality on Cosmos-SDK-based chains
