  • 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

• Strong DeFi stack knowledge: Solid understanding of architectures and mechanics of:
  • Morpho Blue
  • Fluid
  • Aave V3

• 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
