THE ROLE

We are looking for a passionate Blockchain Developer to take ownership of smart contract development, ZK proof integration, and our cross-chain payment pipeline. You will work directly with our Lead/Project Manager and a team of engineers to build the protocol's core infrastructure.

Key Responsibilities:

• Design, develop, and deploy smart contracts for our ConfidentialPayroll protocol across Ethereum, Solana, and other VMs

• Integrate zero-knowledge proof systems (Ligero/Arc) for transaction privacy and compliance

• Implement cross-chain settlement mechanisms using Circle's CCTP and Hyperlane

• Integrate FHE (Fhenix/Zama) for encrypted state management of payroll rosters

• Build and maintain the backend API orchestrator (Express/TypeScript) to manage the 7-stage payment pipeline

• Write secure, well-tested, and documented code for our core infrastructure

• Collaborate with the team on architecture decisions and technical roadmap

REQUIREMENTS

• 3+ years of software development experience, with at least 2 years of hands-on blockchain development

• Deep expertise in Solidity and experience with EVM-compatible chains (Ethereum, Base, Arbitrum, Polygon)

• Strong proficiency in TypeScript/JavaScript for backend development (Node.js)

• Experience developing and deploying smart contracts in production environments

• Understanding of ZKPs (Zero-Knowledge Proofs) and their application in privacy-preserving protocols

• Experience with cross-chain messaging protocols (e.g., Hyperlane, Wormhole, CCTP)

• Knowledge of cryptography fundamentals and blockchain security best practices

• Excellent communication skills and ability to work effectively in a fully remote, asynchronous environment

Bonus Points (Nice to Have):

• Experience with Solana development (Rust/Anchor)

• Familiarity with FHE libraries (Zama, Fhenix)

• Experience building payroll or payments infrastructure

• Understanding of Circle CCTP attestations and burn-and-mint mechanics
