Position Overview

Reporting to the Director of Portfolio Construction and Implementation Strategy, the Analyst is a member of the implementation strategy team and supports the firm’s efforts to translate research views into client portfolios with maximum fidelity. The role is hands-on, data-driven, and quantitative: the Analyst will run analyses, build tooling, and execute studies that inform decisions about portfolio construction, optimization, rebalancing, and execution across the firm’s product suite. The successful candidate will meaningfully contribute to the goal of efficiently exposing clients to value-add features defined by the Research department while controlling risk, cost, operational complexity, and account-specific considerations.

The Analyst will collaborate cross-functionally with Portfolio Management / Implementation, Research, Trading, and the Quantitative Investment Platform (QIP) team, contributing to firm-wide initiatives that improve risk-adjusted returns net of all costs. The role is a high-impact seat with direct exposure to senior investment leadership and offers the opportunity to develop deep expertise in portfolio construction, optimization, and implementation at a systematic investment manager.

Key Job Responsibilities

• Portfolio Construction Analysis: Execute studies of signal capture, turnover sensitivity, transaction costs, constraint impact, factor decomposition, rebalance frequency, and parameter selection; synthesize results into decision-ready summaries for senior stakeholders.

• Optimizer and construction tooling: Build and extend tooling around the firm’s optimization engine and related infrastructure, including parameter sweeps, frontier studies, scenario simulations, and pre-trade ‘what-if’ analyses.
• Implementation monitoring: Maintain monitoring of signal exposure, transfer coefficients, constraint shadow costs, turnover, tracking error, and realized vs. expected costs.
• Execution and rebalance analytics: Support evaluation of portfolio construction and execution strategies, transaction cost models, and rebalance timing/frequency in partnership with Trading and Implementation.
• Data, technology, and new products: Build reproducible data pipelines and analytics within the firm’s codebase; partner with QIP and Engineering on construction and implementation tooling; contribute analytical work to the firm’s expansion into alternatives and new product types.
• Documentation and collaboration: Document methodologies, tools, and processes to institutional standards; represent the implementation strategy team in cross-functional working groups.
