Senior System & Integration Analyst (f/m/x)

About the project

We are looking for an experienced Senior System & Integration Analyst to join a long-term project within a large international organization from the financial sector.

The role combines system analysis, requirements engineering and integration design. You will act as a bridge between business and technical teams, translating business needs into clear technical requirements, integration designs, API specifications and data models.

This is an analytical and design-focused position rather than a software development role. Strong hands-on experience with REST API design and UML is particularly important.

Your responsibilities

• Conduct stakeholder interviews and workshops to gather business and technical requirements.

• Analyze existing systems and documentation to identify gaps and improvement opportunities.

• Document functional and non-functional requirements.

• Create and maintain technical documentation, including requirement specifications, process flows and system designs.

• Design REST APIs following best practices and architectural standards.

• Create UML diagrams and BPMN process models.

• Develop user stories and clear acceptance criteria.

• Create logical and physical data models and database schemas based on business requirements.

• Design integration patterns and data flows between systems.

• Work closely with business stakeholders, developers, architects and other technical teams.

• Facilitate cross-functional workshops and design sessions.

• Review requirements and design artefacts to ensure quality and consistency.

• Ensure solutions and documentation comply with data governance and management standards.

Our requirements

• Strong experience as a System Analyst, Integration Analyst, Business/System Analyst or in a similar role.

• Expert-level knowledge of REST API principles, design patterns and best practices.

• Hands-on experience designing scalable and maintainable APIs — not only consuming or testing existing ones.

• Strong practical knowledge of UML and experience creating system documentation and diagrams.

• Very good knowledge of BPMN and business process modelling.

• Strong requirements gathering and analysis skills.

• Practical knowledge of SQL and relational databases.

• Experience with Data Modelling, including logical and physical data models and relationships between entities.

• Understanding of Data Governance and Data Management principles.

• Good understanding of software development lifecycle methodologies such as Agile, Waterfall and DevOps.

• Experience working with cross-functional technical teams.

• Strong stakeholder management and communication skills.

• Ability to create clear and comprehensive technical documentation.

• Understanding of enterprise architecture principles.

• Good command of English (minimum C1).

Optional

• Knowledge of SOAP / WS-* and XML-based web services.

• Experience writing acceptance criteria using Gherkin (Given/When/Then).

• Experience with Git-based version control platforms.

• Previous experience working in a large enterprise or financial environment.
