We are a small team of engineers and traders who have built market infrastructure at Tower Research, Citadel, Coinbase, and Bloomberg. We care deeply about performance, correctness, and building systems that operate at global scale. Hibachi is backed by Dragonfly Capital, Electric Capital, Coinbase Ventures, and Circle Ventures.
About The Technology
Hibachi runs a high performance off chain central limit order book built for fast, private trading and deep liquidity. Zero knowledge proofs allow anyone to verify the exchange’s solvency on chain without revealing user positions. The result is transparent infrastructure built for global markets.
The Role
We\'re looking for a seasoned Smart Contract Engineer to own the onchain layer of Hibachi\'s infrastructure. This means writing and auditing the contracts that custody funds, settle trades, and verify ZK proofs — code that operates in adversarial conditions where correctness is non-negotiable. You\'ll work closely with our core systems team to bridge the offchain CLOB with onchain settlement, and you\'ll help shape how we think about cross-chain interoperability as we expand across networks.
Responsibilities
Designing, writing, and deploying production-grade Solidity contracts across settlement, custody, and verification layers
Owning the integration between our ZK prover and onchain verifier contracts
Architecting and maintaining cross-chain messaging infrastructure, including bridge integrations and message-passing protocols
Conducting internal contract reviews and working with external auditors to maintain a rigorous security posture
Collaborating with the core Rust engineering team to ensure seamless handoffs between offchain execution and onchain settlement
Staying ahead of the smart contract security landscape — known attack vectors, emerging patterns, and evolving best practices
Qualifications
4+ years of professional Solidity experience, with production contracts deployed and battle-tested on mainnet
Deep understanding of the EVM — opcodes, gas optimization, storage layout, and edge cases
Hands-on experience with cross-chain messaging protocols (LayerZero, Wormhole, or similar)
Strong security instincts — familiarity with common vulnerability classes (reentrancy, front-running, oracle manipulation, etc.) and experience either conducting or participating in audits
Comfort owning the full contract lifecycle: design, testing, deployment, monitoring, and upgrades
Familiarity with Foundry for testing and development tooling
Nice-to-have
Experience with ZK proof verification onchain — integrating with Groth16, PLONK, or similar proving systems
Cryptography fundamentals — elliptic curves, tries, commitment schemes, and how they apply in a smart contract context
Familiarity with formal verification tooling (Certora, Halmos, or similar)
Background in DeFi protocol design, particularly around settlement, margining, or order book mechanics
Experience across multiple EVM-compatible chains and an understanding of how their differences affect contract design
