Job Summary
Job Description
šBilateral & On-Chain Lending: Execute and manage the end-to-end lifecycle of borrowing and lending transactions. This includes negotiating bilateral term sheets with institutional counterparties and managing liquidity across DeFi money markets (e.g., Aave, Morpho, Euler). šRate Structuring (Fixed & Float): Manage the firmās interest rate profile. You will monitor the spread between fixed-term institutional loans and floating-rate DeFi protocols, identifying when to lock in term funding versus staying floating based on market volatility and STIR (Short-Term Interest Rate) trends. šCollateral Scoring & Haircut Optimization: Develop and maintain a proprietary collateral scoring framework. You will determine appropriate haircuts for various asset classes (Fiat, Stablecoins, Blue-chip Crypto, and RWAs) based on liquidity, volatility, and smart contract risk. šContractual Execution: Work closely with Legal and Risk to navigate ISDA/GMRA-like frameworks in a digital asset context. You should be comfortable discussing rehypothecation rights, delivery-versus-payment (DvP), and event-of-default triggers. šTechnical Automation: Use Python to build tools that monitor real-time "Health Factors" and LTVs. You will automate interest rate tracking across fragmented venues and build dashboards that score counterparty risk and collateral quality dynamically. šCounterparty Management: Act as a primary point of contact for institutional lenders and liquidity providers. You will represent Keyrockās desk to ensure we are the "borrower of choice" by maintaining transparent and data-driven reporting on our collateral positions.
Required Profile
šThe STIR/Repo Foundation: 4ā7 years of experience on a Repo, Securities Lending, or STIR desk. You must have a deep understanding of the mechanics of secured financing, including margin calls, substitution of collateral, and term structures. šAnalytical Rigor: Proven ability to "score" assets. You don't just accept a 20% haircut; you can explain the quantitative reasoning behind why a haircut should be 15% or 25% based on market depth and liquidation slippage. šTechnical Proficiency: Strong Python skills are non-negotiable. You will be expected to script your own monitoring tools and query on-chain data to verify protocol health or collateral balances. šEntrepreneurial Drive: You enjoy the "blank canvas" of the crypto markets. You are eager to take TradFi repo concepts and rebuild them for a 24/7, high-velocity digital environment.
