Job Description:

What is Renegade?Renegade is building an unstoppable network for the anonymous exchange of value. Our core permissionless protocol, the Renegade dark pool, solves many problems in current decentralized exchange design: front-running, quote fading, copy trading, toxicity discrimination, and fragmented liquidity.Based on zero-knowledge and multi-party cryptography, Renegade allows for complete trade privacy during the entire trade lifecycle. Zero information about orders, balances, past trade history, or collateral values can leak to third-parties, allowing for strong anonymity guarantees and best execution for large whale traders.Dark pools are well-understood pieces of traditional finance market structure, accounting for 20-40% of TradFi equities volume. We are building the crypto-native analog of dark pools.Renegade is a seed-stage startup backed by some of the best crypto investors, including Naval Ravikant, Dragonfly Capital, Balaji Srinivasan, Tarun Chitra, and Lev Livnev. We work in-person in downtown San Francisco, 6 days a week.What You'll DoAs a cryptography engineer, you will work closely on our ZKP and MPC proving stacks. You will implement core cryptographic primitives (SPDZ, Bulletproofs, ElGamal, etc.) and optimize them for low-latency execution. In addition, you will help with internal audits, ensuring that Renegade maintains consistent state while being as flexible and expressive as possible.You'd be a good fit if..

• You have a background in pure math, cryptography, or security research.
• Have familiarity with zero-knowledge proofs and multi-party computation, or can pick it up quickly.
• Able to work with zero-knowledge cryptography libraries, including Arkworks, Circom, and Dalek.
• Able to work with StarkNet and the Cairo language.
• Have worked on practical zero-knowledge proof implementations, being able to write latency-optimized code in addition to understanding the core cryptography.Our Stack
  • Cryptography: Maliciously-secure SPDZ for MPC, and Bulletproofs for ZKP verification.
  • Languages: Rust for the protocol-layer, Typescript for interfaces and CLI.
  • Networking: libp2p for peer discovery.
  • Settlement: StarkNet for scalability and consensus.We very much look forward to chatting further!
