Your role

As a Functional Analyst, you bridge the gap between business and IT: you translate needs and processes into clear, implementable requirements, and you create a shared understanding between stakeholders and the development team throughout the entire analysis and delivery process. You get the space to help shape how a team and an organization work, and your work makes a visible difference: turning a vague idea into a solution that is actually built and used.

As a Functional Analyst, your tasks will include:

• Gathering needs and translating them into clear user stories in collaboration with business and IT stakeholders.

• Organizing and facilitating workshops to define scope, validate assumptions, and work with the business to translate ideas into a visually appealing application.

• Modeling processes and functional behavior using UML and BPMN.

• Drawing up test scenarios to verify that the built solution meets the requirements.

• Writing user stories and defining acceptance criteria.

Your hard skills:

• You have in-depth knowledge of analysis methods and modeling techniques (UML, BPMN, XML and web services). You have experience supporting E2E testing.

• You have experience writing Use Cases using UML, Story Mapping and MoSCoW prioritization.

• You have experience with modeling and design tools such as Enterprise Architect, Visio, Figma, Balsamiq,...

• You are skilled in using collaboration tools such as Jira and Confluence.

• You have experience using testing tools such as SoapUI, Postman, Swagger.

• You have a basic knowledge of SQL, JSON, XML and/or web technologies (HTML/CSS3)

• You have experience with AI tools and prompting, given the growing role of AI in analysis and delivery processes.

Your profile

• You have at least 5–8 years of relevant experience as a Functional Analyst.
