NATO - Senior C3 Taxonomy & Information Architecture Consultant vacancy in OFF-SITE (055cm) Overview

Influence NATO’s Enterprise C3 Data Model. Our client is seeking a senior-level C3 Taxonomy and Information Architecture specialist to support NATO’s Allied Command Transformation (ACT) through the NCI Agency. This role sits at the heart of NATO’s Federated Mission Networking (FMN) framework and supports the development of the Consultation Command & Control Taxonomy (C3T) – the authoritative classification structure underpinning Alliance-wide C3 capability alignment.

You will play a central role in redesigning key taxonomy layers, shaping Baseline 8 (BL8), and aligning NATO C3 Taxonomy structures with FMN Spiral 7 interoperability requirements. This is specialist work at the intersection of defence, data architecture, and operational capability modelling.

NATO’s current C3 taxonomy structures require analytical redesign, structural refinement, and improved alignment with operational frameworks. You will:

• Redesign and improve existing C3 Taxonomy layers
• Lead analytical proposals for structural change
• Develop and maintain BL8 taxonomy updates
• Align taxonomy hierarchies with FMN Spiral 7
• Support taxonomy change management and governance
• Contribute directly to the authoritative Tidepedia C3T Wiki

This is a delivery-focused consultancy role with clearly defined milestones and measurable outputs.

• Review and redesign the Capabilities Taxonomy (currently deemed not fit for purpose)
• Enhance Business Process and Information Product taxonomies
• Design and structure a new Data Taxonomy
• Identify missing NATO capabilities within the proposed data model
• Analyse and propose structural change options with justified recommendations

• Support the ACT-led C3 Taxonomy change control process
• Implement approved taxonomy changes directly in the C3T Wiki
• Maintain traceability of Requests for Change (RFCs)
• Deliver structured monthly change reports

• Engage military and technical stakeholders to elicit taxonomy requirements
• Support development of C3T Baseline 8 (BL8)
• Deliver analytical alignment of C3T BL8 with FMN Spiral 7
• Brief Architecture Capability Teams and support workshops with National Architects

NATO are looking for a specialist who combines defence domain understanding with strong analytical and information architecture capability. You will demonstrate:

• Minimum 7 years’ experience in taxonomy development, data architecture or business analysis within IT environments
• At least 5 years’ experience in NATO IT, defence contracting, or NATO agencies
• Expert-level knowledge of Information Architecture and systems engineering techniques
• Proven experience designing hierarchical classification structures, metadata schemas or controlled vocabularies in defence contexts
• Experience working with NATO taxonomy frameworks (C3T, STANAGs, NIST 800-60 etc.)
• Strong knowledge of NATO Core Metadata Specification and structured data standards
• Experience using Semantic Media Wiki (e.g. Tidepedia)
• Proven experience eliciting and documenting requirements from military stakeholders
• Strong data analysis capability (validation, structure review, classification logic)

You must hold a valid NATO SECRET clearance (clearance in progress acceptable).

• Primarily remote delivery
• Office and secure access provided at NCIA The Hague when required
• Attendance required: up to 2 Architecture Capability Team meetings (Europe, 3 days each), and up to 2 Project Team meetings (The Hague, 3 days each)
• Contract through 31 December 2026
• Travel included within engagement pricing

• Direct impact on NATO’s authoritative C3 data model
• Influence Alliance-wide interoperability frameworks
• Work at the core of FMN development
• High-visibility engagement with ACT and NATO architecture communities
• Ideal for senior defence data architects or former NATO CIS/architecture professionals transitioning to consultancy
