Would you like to join the leading international intergovernmental organization? The NATO Communications and Information Agency (NCIA) is seeking an experienced NIRIS Software Developer to support the continued development, maintenance, and evolution of the Networked Interoperable Real-Time Information Services (NIRIS) software baseline. NIRIS serves as a critical interoperability assurance capability for NATO, enabling real-time data exchange across multiple tactical data links and operational systems. Responsibilities: 1. NIRIS Baseline Software Development (45% of effort) Develop, update, and maintain NIRIS software modules in accordance with agreed requirements, priorities, and release planning (NIRIS 4.7 and 4.8). Evolve Java software components to support sustained compatibility with supported Java LTS runtimes. Implement agreed functional enhancements, including CESMO integration (Electronic Surveillance information exchange) and historic track data capabilities (filtered retrieval from stored NIRIS recordings). Enhance the RTS subscription mechanism and UI to support filtering by source name, time interval, geolocation, and track number. Prepare software baselines for integration, testing, acceptance, and release. 2. Testing and Verification Support (15% of effort) Develop and maintain unit tests and automated tests for implemented software changes. Support regression testing to ensure software quality, maintainability, and early defect detection. Ensure test coverage of at least 85% for delivered changes where technically applicable. 3. Logging and Troubleshooting Improvements (10% of effort) Enhance NIRIS logging functionality, including per-port, per-endpoint, and per-interface logging. Implement logging filters, improved stack trace handling, log compression, and framework migration as required. Enable more efficient identification and analysis of runtime errors and operational incidents. 4. Interface and Interoperability Support (16% of effort) Maintain and improve NIRIS interfaces with external systems, including support for Link 16 / JREAP, OTH-Gold, DIS, VMF, AIS, and other agreed formats. Provide technical support for interoperability test events (CWIX, TDLITS, INTEND, customer visits). Address OANT/SMAQ configuration issues and analyser limit challenges. 5. Documentation Maintenance (14% of effort) Update user manuals, governance documentation, technical design documents, interface documentation, test documentation, and release-related artefacts. Ensure all documentation remains accurate, current, and consistent with the implemented software baseline. 6. Agile Coordination & Reporting Participate in sprint planning, daily stand-ups, sprint reviews, and project meetings. Track progress using agreed tools (Jira or equivalent) and proactively communicate risks or deviations. Submit Deliverable Completion Reports with evidence of code commits, test results, and traceability to acceptance criteria.
