Highest Paying Web3 Jobs

About the Role

HAVOK LABS is building at the frontier of Web3 innovation. We’re looking for a Senior Blockchain Developer who lives and breathes decentralized tech. You won’t be writing Solidity tutorials or tinkering with testnets — you’ll be deploying real smart contracts, building bots that move markets, and launching tokens with liquidity strategies that actually work.

If you have deep experience with EVM chains, Rust-based ecosystems, and multichain protocols — this role is built for you.

Key Responsibilities

• 🔹 Architect and develop smart contracts on EVM-compatible chains (Solidity) and Rust-based chains (Solana, Sui, Aptos, etc.)
• 🔹 Build and optimize on-chain bots for trading, arbitrage, and liquidity provisioning
• 🔹 Design and deploy liquidity pools, staking mechanisms, and yield farming protocols
• 🔹 Lead token launches — from contract design and security to liquidity bootstrap and community deployment
• 🔹 Integrate with DEXs, bridges, wallets, and oracles (Uniswap, PancakeSwap, SushiSwap, Chainlink, etc.)
• 🔹 Develop and maintain off-chain services like backend APIs, indexing services (e.g. The Graph), and monitoring tools
• 🔹 Stay ahead of exploits and vulnerabilities — security-first coding is non-negotiable
• 🔹 Collaborate with UI developers, product owners, and other team members to ship end-to-end decentralized applications

Preferred Tech Stack

• Smart Contracts: Solidity, Rust (Sui, Solana), Move
• Chains & Platforms: Ethereum, Polygon, Arbitrum, Optimism, BSC, Solana, SUI, XRPL, TON (bonus)
• Dev Tools: Hardhat, Foundry, Truffle, Anchor, CosmWasm, Geth
• APIs & Backends: Node.js, TypeScript, Python, PostgreSQL, Redis
• Bots & Scripts: MEV, sandwich bots, arbitrage bots, liquidity monitors
• Security: Familiarity with audits, fuzzing, slither, certora or formal verification tools
• Infrastructure: IPFS, Infura, Alchemy, QuickNode, The Graph

Requirements

• ✅ 3–6+ years of hands-on experience with smart contract development
• ✅ Deep knowledge of Ethereum and EVM internals (gas optimization, memory layout, proxies, etc.)
• ✅ Proven experience in Rust-based chain development
• ✅ Experience building or integrating liquidity pools, token swaps, and on-chain utilities
• ✅ Strong understanding of DeFi mechanisms, tokenomics, and governance frameworks
• ✅ Solid grasp of blockchain security best practices
• ✅ Experience in launching tokens and managing full-cycle Web3 product launches
• ✅ Strong Git discipline and ability to document and test your code rigorously
• ✅ Proactive, self-starter attitude with excellent problem-solving skills

Nice to Have

• 🌐 Experience working with SUI, XRPL, TON
• 🧠 Familiarity with zk-SNARKs, L2 rollups, and privacy-preserving contracts
• 🛠️ Built and deployed bots for arbitrage, liquidation, or trading
• 🎯 Deployed live DeFi products with active user bases
• 🧪 Experience participating in audits or bounty-driven testing
