We are seeking a Senior DeFi Developer to architect, build, and deploy high-performance systems across major decentralized finance ecosystems. You will lead the development of automated DEX trading strategies, smart contract infrastructure, and on-chain execution systems across EVM chains, Solana, and emerging networks. You will work on high-frequency DeFi execution, liquidity management systems, transaction bundling, sniping, triangular arbitrage, and yield optimization — pushing the edge of on-chain strategy and infrastructure. On-chain native required.
Location: London | Dubai | Hybrid
Type: Full-time
Compensation: Competitive base + meaningful performance incentives
Responsibilities
- Design and implement automated DEX trading systems, including execution on concentrated liquidity AMMs and perpetual futures protocols.
- Develop smart contracts for liquidity provisioning, arbitrage execution, flashloan-based strategies, and collateralized trading.
- Build and maintain high-performance blockchain listeners and off-chain bots for on-chain monitoring and transaction orchestration.
- Implement MEV-aware execution strategies, including Jito validator integration on Solana and bundle building for private or obfuscated submissions.
- Develop systems for multi-wallet creation, transaction obfuscation, and bundled transactions to enhance anonymity and execution efficiency.
- Execute algo-trading strategies across memecoins, new token launches, and triangular arbitrage opportunities.
- Build systems for automated liquidity management on concentrated liquidity DEXs (e.g., Uniswap V3, Orca Whirlpools).
- Optimize transaction fees (gas, compute units) across EVM and Solana chains.
- Contribute to strategy ideation, simulation, backtesting, and parameter optimization.
- Collaborate closely with quant researchers to translate trading ideas into fully automated on-chain execution.
