The Mission

About the Role

We are pioneering frictionless non-custodial crypto deposits, on-chain verifiable sweepstakes, and instant liquidity vault integrations. In this role, you will build secure smart contracts and off-chain signer daemons handling millions in multi-chain volume daily.

Day-to-Day Execution

What You'll Architect & Build

Develop battle-tested smart contracts in Solidity and Rust (Solana Anchor) for deposit vaults and staking mechanics.
Build high-performance off-chain transaction signers and gas optimization algorithms.
Coordinate external formal verification audits with top security firms (CertiK, OpenZeppelin).
Implement MPC (Multi-Party Computation) and institutional hot/warm/cold wallet management systems.
Design cross-chain messaging bridges and Layer 2 rollup settlement pipelines.

Qualifications

What We Look For

5+ years in production blockchain development with a portfolio of verified, high-TVL smart contracts.
Expertise in Solidity, Foundry/Hardhat, and Rust/Anchor on Solana.
Exemplary track record with smart contract security best practices and reentrancy/flash-loan mitigation.
Experience integrating institutional custody APIs (Fireblocks, BitGo, Copper) is a major plus.
Solid foundation in cryptography (ECDSA, Ed25519, Zero-Knowledge proofs).
