• Product mindset with strong analytical and problem-solving skills.

Nice to Have:

• A dynamic and collaborative environment within a growing fintech company;
• Opportunities to work with modern technologies and impactful products;
• Career growth and development opportunities in the fintech industry;
• A bureaucracy-free team that values ideas and individual contribution.
• AI-First Analysis — AI is integrated into our daily work to accelerate analysis, documentation, and solution discovery;
• Evidence over assumptions — validate financial logic using data, transaction flows, and system behaviour;
• Multi-context thinking — comfortably switch between multiple clients, product initiatives, and financial domains throughout the day;
• Ownership — independently investigate business problems before proposing solutions;
• Continuous learning — build deep expertise in payments while documenting knowledge for the wider engineering organization.
