From the employer

Key Responsibilities

• On-Chain Risk & Credit Modeling: Develop and refine quantitative risk models to assess protocol health, collateralization ratios, liquidation risks, and smart contract vulnerability exposure across DeFi credit platforms.
• Yield Optimization & Execution: Build Python-based tools and algorithmic models to analyze real-time yield curves, liquidity pool depth, and funding rate arbitrage across lending and borrowing protocols.
• Data Analytics & Telemetry: Query on-chain telemetry, EVM event logs, and DEX/lending protocol data using SQL, Subgraphs, and Python to generate actionable insights for credit positioning and risk allocation.
• Protocol Due Diligence & Forensics: Perform quantitative forensics and stress testing on emerging lending primitives, liquid staking protocols, and structured credit products prior to capital deployment.

Requirements

• Technical & Quantitative Skills: Strong code-first foundation in Python and SQL (with Git proficiency) for handling on-chain or EVM event data. Understanding of smart contract mechanics and DeFi primitive math (e.g., automated market makers, lending pool utilization curves, liquidation thresholds).
• Quantitative & Trading Mindset: Rigorous background in a quantitative field (Math, Physics, CS, Finance, or Engineering) with a systematic/trading mindset. Ability to model yield dynamics, credit risk, backtesting strategies, and protocol insolvency scenarios.
• DeFi "Skin in the Game": Hands-on experience interacting with decentralized lending protocols (e.g., Aave, Morpho, Compound, Maker/Endgame), yield aggregators, or credit markets.
• Nice-to-Haves: Familiarity with Rust, Solidity, Foundry, or specialized credit risk models and backtesting frameworks.
