You’ll be focused on enhancing and maintaining the core analytics platform – handling everything from integrating new MSCI data sets to optimising complex calculations used in portfolio construction and alpha generation.

Key responsibilities:

• Work with MSCI and other structured data feeds – identify gaps, map schema changes, and ensure accurate downstream calculations
• Translate investment logic into efficient, production-grade Python code
• Optimise performance of existing quant models and analytics
• Manage and enhance data workflows – Snowflake, AWS, Python
• Liaise daily with investment professionals to understand requirements and deliver solutions

What we’re looking for:

• Strong Python developer with deep experience using statistical and numerical libraries (NumPy, pandas, SciPy etc.)
• Proven experience supporting quant or systematic investment strategies
• Good understanding of infrastructure – ideally AWS and Snowflake – and willingness to own setup and tooling
• Comfortable working in fast-paced front office environments with direct exposure to the investment team
• Detail-oriented, pragmatic, and able to work independently

Initial 6-month contract with long-term scope. Hybrid working model (3 days in the office). Up to £900/day, may be some flex for top end candidates.
