We are looking for an experienced Business/System Analyst to join the team responsible for the financial module of our payment platform.

The module covers financial calculations, transaction and financial reporting, reconciliation processes, reporting APIs, client-specific configurations, and other functionality supporting the financial operations of our clients.

The analyst will work closely with Product, Engineering, QA, Support, and client-facing teams, helping transform business needs into well-defined requirements and supporting functionality throughout its lifecycle — from initial discovery and analysis to implementation, acceptance, documentation, and production rollout.

• Investigate complex client scenarios and production issues;
• Support QA with edge cases and perform functional acceptance;
• Document financial logic, configurations, APIs, and implementation scenarios;
• Collaborate with Product, Engineering, QA, Support, and clients across multiple initiatives.

Requirements:

• Strong understanding of payment processing and transaction lifecycles;
• Experience analysing financial calculations, reconciliation, settlements, fees, FX, and transactional data;
• Strong SQL skills for data analysis and validation;
• Comfortable working with REST APIs, Postman, logs, and databases;
• Ability to investigate complex system behaviour rather than relying on assumptions;
• Experience writing clear functional specifications and acceptance criteria;
• Comfortable switching between multiple clients, products, and priorities;
• Product mindset with strong analytical and problem-solving skills.

Nice to Have:

• Experience with a PSP, payment processor, acquirer, payment gateway, or bank;
• Experience with high-volume transactional systems;
• Knowledge of merchant settlement, reconciliation, and multi-currency processing;
• Experience supporting client onboarding and configurable financial platforms.

What we offer:

• A dynamic and collaborative environment within a growing fintech company;
• Opportunities to work with modern technologies and impactful products;
• Competitive salary;
• 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.
