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. Responsibilities

Execute and manage the end‑to‑end lifecycle of bilateral and on‑chain lending transactions, including negotiating bilateral term sheets with institutional counterparties and managing liquidity across DeFi money markets (Aave, Morpho, Euler). Manage the firm’s interest rate profile by monitoring the spread between fixed‑term institutional loans and floating‑rate DeFi protocols, and deciding when to lock in term funding versus staying floating based on market volatility and short‑term interest rate trends. Develop and maintain a proprietary collateral scoring framework, determining appropriate haircuts for various asset classes (Fiat, Stablecoins, Blue‑chip Crypto, and RWAs) based on liquidity, volatility and smart‑contract risk. Work closely with Legal and Risk to navigate ISDA/GMRA‑like frameworks in a digital‑asset context, including rehypothecation rights, delivery‑versus‑payment and event‑of‑default triggers. Use Python to build monitoring tools that track real‑time health factors and LTVs, automate interest‑rate tracking across venues and build dashboards that score counterparty risk and collateral quality dynamically. Act as the primary point of contact for institutional lenders and liquidity providers, representing Keyrock’s desk and maintaining transparent, data‑driven reporting on collateral positions.

Required Profile

4–7 years of experience on a Repo, Securities Lending or STIR desk, with deep understanding of secured financing mechanics (margin calls, collateral substitution, term structures). Proven analytical rigor in scoring assets, able to justify haircut percentages based on market depth and liquidation slippage. Strong Python skills for scripting monitoring tools and querying on‑chain data to verify protocol health or collateral balances. Entrepreneurial drive to apply traditional repo concepts to a 24/7, high‑velocity digital environment. Knowledge of DeFi mechanics:

Required: Understanding of over‑collateralized on‑chain lending (utilization curves, liquidation logic). Preferred: Familiarity with real‑world assets (RWA) used as collateral.

What We Offer

A competitive salary package. Autonomy in time management thanks to flexible working hours and remote work opportunities. The freedom to create an entrepreneurial experience within a team that pursues excellence.

We welcome employees of all backgrounds and hire, reward and promote entirely based on merit and performance. Background checks are required before joining Keyrock. #J-18808-Ljbffr
