• Enable users to pull from flexible data sources, including trades, positions, pricing, and fees
• Implement filtering, sorting, grouping, and transformation capabilities within reports
• Allow users to save report configurations for future use, with potential scheduling capabilities
• Partner directly with Accounting and Settlement stakeholders to gather requirements and validate outputs
• Deliver a production-ready component integrated into our Backoffice infrastructure
• Produce clear technical and user documentation and present your results at the end of the internship

Goals

• Deliver a valuable internal tool used by Backoffice stakeholders
• Reduce the burden of ad hoc report generation on the development team
• Provide a controlled, customizable in-house reporting solution
• Build strong habits around stakeholder collaboration, iterative development, and documentation

• At least 1 year of experience using C# and/or Java
• Exposure to TypeScript and React is beneficial
• Curiosity, self-motivation, and strong communication skills—especially when working with non-technical stakeholders
