HAVOK LABS
$65k - $1000k
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
