API Analyst

Our client is seeking an experienced API Analyst to join their Integration Team. This team supports the organization in designing, standardizing, managing, and further developing integration solutions and APIs within an integration landscape utilizing technologies such as AXWAY and Fuse. The role has a clear link to application, integration, and technology architecture: the API Analyst translates architectural guidelines into applicable API agreements for development teams. Additionally, the API Analyst contributes to a composable architecture by helping to define APIs as reusable, well-documented, and decoupled building blocks within the application and integration landscape.

This role is explicitly not an API developer role, but an enabling role: the consultant guides, advises, and supports development teams in correctly and consistently designing, documenting, publishing, and using APIs.

• →Support development teams in analyzing, designing, and documenting APIs.
• →Draft and maintain API specifications, for example in OpenAPI/Swagger.
• →Monitor API standards, naming conventions, version control, error handling, security guidelines, and documentation quality.
• →Actively participate in meetings between business analysts, functional analysts, development teams, architects, security, and operational teams.
• →Analyze existing APIs and integration patterns and propose improvements, standardization, and reuse.
• →Support API governance, including reviewing API designs and aligning with architectural guidelines.
• →Coordinate API designs and integration choices with enterprise and solution architecture to ensure solutions fit within applicable architectural principles and integration standards.
• →Assist development teams in applying composable architecture principles, ensuring APIs, services, and integration patterns contribute to a modular, reusable, and manageable application landscape.
• →Contribute to knowledge sharing, documentation, templates, and guidelines for API development within the team and the organization.
• →Collaborate on the further professionalization of the Integration Team as an enabling team for development teams.

• Experience with functional and technical analysis within IT projects or software development.
• Experience with API analysis, API design, or integration analysis.
• Good knowledge of REST APIs, API contracts, OpenAPI/Swagger, and JSON.
• Good understanding of integration principles, such as synchronous/asynchronous communication, event-driven integration, message queues, or middleware.
• Knowledge of or experience with ESB environments, preferably AXWAY and Fuse, and insight into the role of APIs within broader integration architectures.
• Knowledge of composable architecture principles, with insight into how APIs, services, ESB platforms, and integration patterns contribute to a modular, reusable, and manageable application landscape.
• Experience with API governance, API lifecycle management, version control, documentation, and reusability of services.
• Knowledge of API security, such as OAuth2, OpenID Connect, JWT, certificates, access control, and secure API design.
• Knowledge of Agile/Scrum and experience collaborating with or within development teams.
