Senior Enhanced Index Portfolio Manager

Description:

We are seeking a highly experienced Enhanced Index Portfolio Manager to join our Portfolio Implementation & Investment Engineering team. With deep expertise in managing passively constructed equity beta solutions, the successful candidate will play a leading role in shaping the evolution of our Enhanced Index strategies, driving process innovation, and ensuring strong alignment between portfolio outcomes and investment intent. The Enhanced Equity business has experienced significant growth in AUM over the last 3 years to £65bn under management and expected to double over the next few years. The new addition to the team will combine deep knowledge of passive equity investing with quantitative and engineering capabilities, contributing to the design, optimisation, and day-to-day implementation of our strategies. As a senior practitioner, you will provide both thought leadership and hands-on portfolio management execution within a collaborative team environment.

In this role, you will lead enhancements to our investment processes—refining models, strengthening portfolio construction, overseeing liquidity and cash equitisation, rebalancing, corporate actions, guideline compliance, and ongoing risk and performance monitoring. You will also drive index methodology and event analysis, translating changes such as additions, deletions, IPOs, free‑float adjustments, and sector reclassifications into proactive portfolio positioning and efficient implementation across mandates. Working closely with Investment Engineering and Trading, you will help design and industrialise scalable tools that improve risk management, liquidity assessment, portfolio construction, execution quality, and operational efficiency. Additionally, you will contribute to innovation across the wider investment platform by challenging established approaches and embedding best‑practice principles that support business growth through next‑generation automation.

Skills and experience we’re looking for:
 

• Proven track record managing passive and enhanced‑index equity portfolios across regional and global markets, using advanced portfolio‑optimisation tools and an engineering mindset to deliver low‑risk equity beta solutions for clients.
• Deep understanding of equity instruments, trading mechanics, market microstructure, benchmark construction, index methodologies and end to end investment processes applied to managing large portfolios (>GBP 100bn).
• Confidence to challenge established processes constructively. Propose evidence-based improvements and ability to translate complex technical ideas into clear concepts for non-specialist stakeholders.
• Naturally inquisitive and innovative, with a passion for solving complex portfolio‑construction, implementation and trading challenges in a team‑based environment.
