About the Role
A rare opportunity to become a key architect of an institutional-quality investment business at launch. The CIO generates proprietary signals and owns the investment decisions; the fund trades within pre-committed tramlines. Your role is to run that machine brilliantly and make it better, ensuring alpha is converted into portfolio returns through superior implementation.
Responsibilities
- Day-to-day implementation of the portfolio: translating validated signals into live basket positions within the fund's construction framework.
- Hedging: implementation of portfolio- and security-level hedges within the fund's hedging framework.
- Factor and risk monitoring: continuous ownership of factor tilts, exposures, and idiosyncratic vs factor risk decomposition.
- Execution quality: transaction cost analysis, liquidity management, and execution efficiency across the programme.
- Provide the daily answer: complete, instant command of P&L attribution, hedge performance, and positioning for the CIO and investors.
- Framework improvement via evidence: proposal rights on construction and hedging parameters, routed through a dedicated backtesting team and approved at committee.
Requirements
- Circa 8–15 years in sophisticated equity long/short environments (multi-manager platforms, systematic funds, central risk books, or institutional asset managers).
- Deep practical expertise in portfolio construction, baskets, hedging and factor management.
- Options experience is essential.
- Strong grasp of market microstructure, execution and transaction cost analysis.
- Python fluency helpful, but not essential.
- Must be based in our London office from Monday to Friday.
- The working day begins at 07:30h London time.
