Our client is looking for a Senior API & Integration Analyst
Description
You have the opportunity to contribute to challenging projects and play a key role in the functional and technical evolution of our software solutions. In this assignment, you will be part of the I‑ICT.211 Traffic Data Solutions team and work on projects that are crucial for the continuity and performance of the company's core business activities. These projects concern the consolidation and distribution of information related to railway traffic management (pre‑processing, realtime, post‑processing, back‑office) to B2B stakeholders, specifically:
Outside our organisation:
- The railway companies operating or running on our network
- Foreign infrastructure managers
- The European platforms for consolidating railway information, such as RailNetEurope, for example.
Within our organisation:
- Realtime display of timetable changes for our signal cabin staff
- Calculation of charges and invoicing for the use of our network by our customers
- Calculation of electricity consumption related to our activities
- Feeding expert systems such as BigData
You work on both new developments and corrective and evolutionary maintenance of existing applications.
As a Senior API & Integration Analyst, you are responsible for analysing the needs related to data exchanges and application integrations between various internal and external stakeholders. You translate these needs into API contracts and functional and technical integration specifications (REST, SOAP), ensuring a shared understanding of the structure, semantics and rules of the exchanged data.
Thanks to your previous experience in development and system integration, you work closely with IT teams, architects, railway companies and other operational units to achieve reliable, coherent and secure integrations.
Main tasks:
- Analysis of integration needs: You identify, analyse and document needs related to data exchange and application integrations, in collaboration with both business and technical stakeholders.
- Data analysis and clarification: You collect, analyse and formalise the data needed for the exchanges, including their meaning, business rules and constraints, and you monitor the consistency between producing and consuming systems.
- Definition of API contracts: You design and document API and web service contracts (REST, SOAP), including data models, message structures, validation rules and error codes.
- Functional and technical integration specifications: You prepare clear and detailed specifications to support the implementation of interfaces and integration flows.
- Collaboration with technical teams: You work closely with development, integration and architecture teams to ensure that technical solutions meet the functional requirements and integration standards.
- Testing and validation of interfaces: You define test cases and test scenarios for APIs, support or perform functional tests and validate the conformity of the exchanges with the defined contracts.
- Impact analysis: You analyse the impact of functional and technical changes on existing integrations and data exchanges.”
