Overview

paytech is a dynamic fintech company dedicated to pushing the boundaries of innovation in the industry.

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.

Key Responsibilities:

  • Discover, analyse, and formalise business requirements;
  • Design implementation-ready functional specifications and acceptance criteria;
  • Analyse transaction flows, financial logic, APIs, data models, and system behaviour;
  • Validate financial calculations and business rules using data;
  • 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.

Job Requirements:

Must Have

  • 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.
