Job Description

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.

Job 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.

Job Requirements

• 5+ years experience in software development and relevant experience in blockchain technologies.


• Degree in Computer Science or related field


• Prior experience with cryptographic protocols, especially zkSNARKS or zkSTARKs


• Experience with a proof assistance such as Idris, Coq, or Agda


• Prior experience in low-level systems programming, ideally in Rust. C++ experience ok.


• Experience with Cosmos-SDK.


• Knowledge of fault-tolerant consensus protocols like PBFT or Raft.


• Ability to write production-quality code.


• Proven track record of delivering applications on time and on budget.


• Experience working with distributed teams across timezones


• Experience designing and building performant and scalable network protocols.


• You are passionate about blockchain, have used DeFi dApps and believe in the opportunity of decentralization and blockchains to change how the financial world works today


• You thrive in a startup environment and feel best working in a small, cross-functional team where you can roll up your sleeves and be hands on


• You have an interest in working in a self organizing environment and bring creativity to start your own initiatives within the Cosmos Stargate SDK
