- Ensure consistency of the hybrid COBOL/Java architecture.
- Provide technical guidance and mentoring to developers through best practices, code reviews, and support with complex components.
- Serve as a key technical escalation point for maintenance and regulatory evolution topics.
- Lead continuous improvement initiatives related to performance, quality, and maintainability.
Development & Maintenance
- Lead and contribute to corrective and evolutive maintenance activities.
- Work on business-critical components, including daily batch import/export processing, data exposure through web services, management and consultation user interfaces, and reference data, contracts, and nomenclature modules.
- Ensure the robustness and performance of batch processes handling large volumes of data in scheduled automated runs.
- Contribute to technical debt reduction within a large legacy application landscape.
- Analyze and troubleshoot incidents across production systems.
Quality, Testing & Industrialization
- Define and implement component, integration, and data flow testing strategies.
- Secure batch processing through restart mechanisms, controls, and monitoring.
- Improve and maintain industrialization processes, including scheduling, shell scripts, and Unix tooling.
- Ensure data quality, traceability, and consistency across systems.
- Manage and control sensitive data flows and reconciliation processes.
- Contribute to the design and evolution of web services for data exposure.
- Perform technical impact analyses related to regulatory changes.
Collaboration
- Work closely with operations teams, testing teams, and business stakeholders.
- Participate actively in incident resolution, including data-related production incidents.
- Ensure alignment across multiple interconnected systems and external data repositories, such as healthcare registries or national datasets.
Accountability
- Ensure the technical and functional quality of RFOS applications.
- Secure critical data flows and reference data systems.
- Proactively contribute to technical and organizational improvements.
- Maintain high-quality technical, functional, and operational documentation.
Required Technical Skills
