Mission Statement
We are looking for an entrepreneurial
Senior Repo & Lending Trader
to drive the execution of Keyrock's bilateral and on-chain borrowing activities. You will be responsible for the "plumbing" of our debt operations—structuring fixed and floating rate loans, optimizing collateral efficiency through rigorous scoring, and managing our institutional lending relationships. This is a role for a technical trader who understands that alpha is often found in superior collateral management and rate structuring.

Job Description

• Bilateral & 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).
• Rate Structuring (Fixed & Float): Manage the firm's 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.
• Collateral 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.
• Contractual 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.
• Technical 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.
• Counterparty Management: Act as a primary point of contact for institutional lenders and liquidity providers. You will represent Keyrock's desk to ensure we are the "borrower of choice" by maintaining transparent and data-driven reporting on our collateral positions.

Required Profile

• The STIR/Repo Foundation: 4–7 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.
• Analytical 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.
• Technical 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.
• Entrepreneurial 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.

• Knowledge of DeFi Mechanics:

• Required: Understanding of how over-collateralized on-chain lending works (utilization curves, liquidation logic).

• Preferred: Familiarity with "Real World Assets" (RWA) and how they are being used as collateral in the current ecosystem.
