EMCD is a global crypto infrastructure company powering millions of users worldwide. Our ecosystem combines a top-7 global mining pool, a secure multi-currency wallet, high-yield crypto savings, and an instant P2P exchange — all in one seamless app.
Were expanding our DeFi capabilities and are looking for a Smart Contract Engineer to build and operate on-chain yield strategies with strong execution guarantees, MEV-aware routing, and production-grade safety.
Responsibilities
- Implement yield strategies: Design contracts and execution scripts for atomic operations such as:
- Looping via flashloans
- Delta-neutral hedging
- Managing YT/PT positions on Pendle
- Programmatic operations via Safe (Gnosis Safe): Automate fund operations using Safe Global, build and execute batch transactions, and integrate with Safe SDK
- MEV & slippage protection: Ensure safe execution of large swaps inside strategies (sandwich protection, optimal liquidity path calculation)
- Cross-chain deployment: Adapt and optimize logic for Ethereum, Solana, and EVM chains, and integrate with external venues/APIs such as Hyperliquid API
Requirements
- Solidity expert: Deep EVM knowledge (storage layout, memory management) and proven gas optimization experience for complex multi-step transactions
- Strong DeFi stack knowledge: Solid understanding of architectures and mechanics of:
- Pendle math: Understanding of Pendle V2 AMM and yield tokenization mechanics (YT/PT)
- Oracles: Experience with Chainlink, Pyth, RedStone, with a strong understanding of price manipulation risks and mitigation patterns
- Testing & tooling: Confident with Foundry including fuzzing and invariant testing
- Safe tooling: Experience with Safe SDK and Transaction Service
- Flashloans: Strong understanding of flashloan mechanics (Uniswap, Aave, etc.)
- Math: Fixed-point math; experience with high-precision arithmetic libraries
Tech Stack
- Solidity, Foundry
- TypeScript / Python
- Safe SDK
- Viem / Ethers.js
Nice to have
- Prior experience building MEV-aware execution (private RPCs, bundle simulation, protection tooling)
- Experience with cross-chain operational tooling and monitoring for strategy health
- Production experience managing strategy risk parameters and circuit breakers
