About the role

As a Financial Back Office Intern at Flanks, you'll join the Product Team and work directly on one of the most data-critical parts of our platform: ensuring that financial portfolios are accurate, well-classified, and correctly loaded.

• Analyse financial data in complex availability situations, identifying gaps and proposing clear, executable solutions.

• Classify and upload financial portfolio data with a focus on accuracy of positions and performance.

• Reconcile financial data across sources, ensuring consistency and correctness throughout the process.

• Review and update internal tools used for financial data management, flagging areas for improvement.

• Propose process improvements based on patterns and issues identified during day-to-day work.

What we'd love to see

• Solid knowledge of financial products — you understand how portfolios, positions, and performance data work.

• Strong analytical mindset with the ability to break down complex data problems and find structured solutions.

• Exceptional attention to detail — accuracy is non-negotiable in this role.

• Reliable adherence to deadlines, with the ability to manage your own workload and flag blockers early.

• Spanish is desirable; French is highly desirable and will set you apart.

• Language Proficiency: Fluent in English to collaborate effectively in our international team ️.
