You will validate and integrate financial data into the optimisation algorithms and ensure results are delivered back to clients in a secure, reliable, and timely way.

Validate and process client data accurately and securely

Identify and implement opportunities to automate processes and workflows

Generate structured reports and formatted output files for delivery to clients and third-party APIs

What We’re Looking For

- Familiarity building data-intensive applications, including use of PyData stack
- Strong problem-solving, communication, and collaboration skills
- Familiarity with Unix/Linux, Git, and SQL
Desirable
- Knowledge of financial derivatives, clearing and the basics of margin and capital regulatory requirements
- Exposure to AI-assisted tools or workflow automation in a secure, responsible engineering environment
- Experience across the full software development lifecycle, and understanding of software design principles (including SOLID), clean code practices, and object-oriented programming
- Affinity with Java and/or C++ programming
