Role Overview

We are looking for a Quantitative Data Scientist to join our Research and Development Team in Milan. This is a critical, high-impact hire designed to be the bridge between complex quantitative modeling and real-world financial application.

You will serve as a key integrator across research, and investment functions, bringing order to innovation.

Key Responsibilities

Critically evaluate ML model outputs to ensure alignment with financial theory and real-world market dynamics, while accounting for client-specific objectives, constraints, and investment frameworks.

Translate research signals into actionable investment strategies and portfolio construction frameworks.

Collaborate with ML researchers to refine models, incorporating financial domain expertise and contributing to model design where needed.

Design, prototype, and scale quantitative models using Python and Java, maintaining a high standard for code quality and modularity.

Contribute to the financial validation layer of the R&D cycle by developing and maintaining test frameworks that identify inconsistencies and support continuous model improvement.

Translate complex portfolio objectives into rigorous, testable modeling specifications that bridge the gap between investment intent and algorithmic execution.

Strong analytical mindset with the ability to communicate complex quantitative insights clearly to both technical and business stakeholders.

Fluent in English (written and spoken).

Nice to Have (Bonus Skills)

Solid understanding of Git-based workflows (branching, code reviews, version control) in collaborative research or production environments.

Experience leveraging LLMs and AI coding tools (e.g., Claude Code, GitHub Copilot) to accelerate prototyping, refactor code, and optimize algorithmic performance.

Proven ability to thrive in high-pressure, collaborative environments , delivering precise results under tight market-driven or project deadlines
