A major European payment processor is expanding its international payments squad to develop DLT and blockchain-oriented payment rails that enable faster, 24/7 cross-border flows. This role exists to translate business needs for banking and payment products into detailed functional and technical requirements, with hands-on work on Swagger APIs and Java technology in an agile squad based in Brussels.
The mission
The programme is part of an initiative to evaluate and deploy Distributed Ledger Technology for cross-border payments, reducing settlement time and increasing transparency across existing rails. The technical landscape includes Java-based microservices, REST APIs documented with Swagger, integrations with payment switches, and cooperation with platform architects. The work matters because it targets production services used by institutional clients and internal business units across multiple countries.
As a senior IT Functional Analyst you will work inside a multi-disciplinary, international squad of 6 to 10 people. Your day to day includes refining features and user stories with product owners, producing detailed functional and technical analyses for developers and test engineers, and following development through to integration, testing and production support. You will also coordinate with other squads and platform teams to ensure consistent API design and adherence to enterprise architecture.
Your responsibilities
- Define detailed functional and technical specifications from business requirements, including data models, process flows and API contracts using Swagger.
- Translate features and user stories into clear development tasks and acceptance criteria that enable timely sprint deliveries.
- Coordinate and align multiple asset teams and architects to ensure coherent design and implementation across applications and services.
- Validate delivered components during development and integration testing to maintain conformity with specified behaviour and non functional constraints.
- Support production deployments and incident analysis, driving corrective actions and updating runbooks and documentation.
- Document solutions and create test scenarios in collaboration with Test Engineers, resolving complex defects and clarifying ambiguous requirements.
Your profile
Essential skills
- 7+ years of functional analyst experience in IT, with demonstrable work on banking and payment products.
