Quantitative Developer

Quant Capital is urgently looking for a Senior Python Quant Developer to join a rapidly growing fintech.

Our client has built a global investment platform that helps investors analyse opportunities, collaborate and make more informed decisions.

They have developed a complex fixed-income model in C# and now need a strong Python engineer to work directly with the quants, understand the existing model and rebuild it into a clean, modular and production-ready Python codebase.

This is a hands‑on role in a small team, with a high level of ownership and impact.

Responsibilities

• Re-engineer a complex C# quant model in Python.
• Refactor and modularise the existing codebase.
• Work directly with quants to productionise the model.
• Productionise the codebase by improving performance, testing and maintainability.
• Build data validation and orchestration processes.
• Work with Pydantic and PostgreSQL.

Required Skills

• Good C# experience.
• Pydantic.
• Strong object-oriented programming skills.
• Experience working with complex numerical or data-heavy systems.

Fixed‑income or broader financial markets experience would be useful but is not essential.

This role would suit an independent developer who enjoys solving difficult technical problems and working in a small, high-impact team.
