Objective of the mission

The National Geographic Institute (NGI) aims to build a modern infrastructure for providing geographic data via OGC APIs, as a complement to the existing infrastructure for offering OGC web services (WMS, WMTS, WFS). This new technology must:

• Be performant: respond quickly and withstand high loads.
• Be reliable: stable and fault-tolerant.
• Be scalable: prepared for future growth and expansion.

The OGC APIs will contribute to:

• Complying with European regulations regarding Open Data, PSI (Public Sector Information), and High Value Datasets.
• Facilitating application development, both internally at NGI and externally.
• Eventually replacing older OGC standards.

This consultancy assignment concerns support in 2026 with:

• Architecture and design of the solution for OGC APIs.
• Implementation and configuration of the infrastructure.
• Optimization for performance, reliability, and scalability.

• Active participation in development (hands-on).

• Estimated total duration of the assignment

Total estimated duration of the assignment: maximum 120 working days. This is an upper limit; depending on the availability and accumulated competence of internal staff, the number of days to be performed by the API architect may be lower.

Profile of the sought consultant

• GIS API architect with proven experience in:
• Design and implementation of API architectures.
• (OGC) API standards and geodata infrastructures.
• Hands-on development and configuration.
• Knowledge of cloud and container technology.
• Experience with performance optimization and API security.
