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
