- Implement various smart contract methodologies including staking, token vesting, liquidity pools, lending protocols, governance mechanisms, and NFT marketplaces
- Develop and maintain scalable, gas-efficient, and secure decentralized applications (dApps)
- Create comprehensive testing frameworks for smart contracts including unit tests, integration tests, and security audits
- Optimize smart contracts for gas efficiency, security, and upgradeability
- Build and maintain middleware services to connect on-chain data with front-end applications
- Collaborate with product teams to translate business requirements into technical specifications
- Contribute to architectural decisions regarding blockchain infrastructure
Technical Requirements
- 3+ years of experience developing and deploying smart contracts to production environments
- Expert-level proficiency in Solidity and experience with at least one other smart contract language (Rust for Solana preferred)
- Demonstrated experience deploying contracts on multiple networks including:
- EVM-compatible chains (Ethereum, Polygon, Arbitrum, Optimism, BNB Chain)
- Solana ecosystem
- Strong understanding of different smart contract patterns and methodologies:
- Staking and reward distribution mechanisms

What is Zero-knowledge?
Zero-knowledge is a concept in cryptography that allows two parties to exchange information without revealing any additional information beyond what is necessary to prove a particular fact
In other words, zero-knowledge is a way of proving something without actually revealing any details about the proof
Here are some examples of zero-knowledge:
- Password authentication: When you enter your password to log into an online account, the server doesn't actually know your password. Instead, it checks to see if the hash of your password matches the stored hash in its database. This is a form of zero-knowledge because the server doesn't know your actual password, just the hash that proves you know the correct password.
- Sudoku puzzles: Suppose you want to prove to someone that you've solved a particularly difficult Sudoku puzzle. You could do this by providing them with the completed puzzle, but that would reveal how you solved it. Instead, you could use a zero-knowledge proof where you demonstrate that you know the solution without actually revealing the solution itself.
- Bitcoin transactions: In a Bitcoin transaction, you prove that you have ownership of a certain amount of Bitcoin without revealing your private key. This is done using a zero-knowledge proof called a Schnorr signature, which allows you to prove ownership of a specific transaction output without revealing the private key associated with that output.
- Secure messaging: In a secure messaging app, you can prove to your contacts that you have access to a shared secret without revealing the secret itself. This is done using a zero-knowledge proof, which allows you to prove that you have access to the secret without actually revealing what the secret is.
