Cryptography Engineer for Zero-Knowledge Proofs and Privacy Applications

You will develop Harmony’s fiat fintech integrations and zero-knowledge proofs products. New cryptographic primitives such as range proofs are prime for broad adoption of privacy with compliance.

You will work on auditable privacy with zk proofs (cryptographic primitives, zk rollup, flyclient, asset swaps, identity for loans). See #zkproof on harmony.one/grants for more of our initiatives.

Qualifications
Extensive experience in zero-knowledge proofs and a deep understanding of cryptographic requirements behind timestamps, preventing double-spending, byzantine fault tolerance, hashing, smart contracts and digital signatures. You should also have an understanding of Harmony’s effective proof of stake consensus mechanism.

• 3-5 years experience with practical cryptography implementation from research to full production
• Strong background in Golang, Rust (zexe), C/C++ (libsnark), JavaScript (aztec)
• Full stack experience (Solidity, Smart Contract, and DeFi App), and developing in Rust in a production environment are a big plus

About Harmony
Harmony is a fast and open blockchain for decentralized applications. Our mission is to scale trust and create a radically fair economy.
Our protocol has achieved secure and random state sharding. Harmony Mainnet supports thousands of nodes in multiple shards, producing blocks in a few seconds with instant finality. Our staking mechanism reduces centralization while supporting stake delegation, reward compounding and double-sign slashing.

Join us if you are excited by the challenge of building zero-knowledge proofs and privacy applications for open financial systems.

About

Our open infrastructure is a revolutionary high-throughput, low-latency, and low-fee consensus platform designed to power decentralized economies of the future. This platform aims to provide a consensus protocol over the open Internet at 10 million transactions per second with 100-millisecond latency.Harmony’s goal is to be 1,000+ times faster and cheaper than Bitcoin and Ethereum. We believe scalability requires optimization across multiple layers. Our full-stack approach applies 10x innovations in networking, systems, and consensus algorithms.
