Data Architect (Generalist)

Freelance Data Architect (Generalist)

The Opportunity

We're looking for a senior, hands-on Data Architect to design and steer enterprise data architecture within a large multinational organisation headquartered in Brussels.

This is not an ivory-tower architecture role. You'll bridge the gap between Business and IT, build consensus across departments, and stay technically credible by building and executing small Proof of Concepts yourself.

If you're the kind of architect who can present a target architecture to senior stakeholders in the morning and validate a design decision in Snowflake or Databricks in the afternoon, this is for you.

What You'll Do

Architecture & Strategy - Design, steer, and implement data architecture tailored to a large-scale, multinational organisational structure.

Stakeholder Management - Gather requirements from Business and IT stakeholders alike, and build a strong internal network across multiple IT departments.

Corporate Navigation - Proactively manage internal dynamics, drive alignment, and build consensus through strong communication.

Hands-on Validation - Independently build and execute small PoCs within the existing toolsets to validate architectural decisions and maintain technical alignment.

What You'll Bring

Technical

Proven experience with Informatica or an equivalent enterprise ETL/ELT platform

Strong expertise in Kimball (dimensional modelling) and Data Vault methodologies

Working knowledge of a modern cloud data platform - Snowflake, Microsoft Fabric, or Databricks - is a strong plus

Experience & Soft Skills

A proven track record of delivering within large, complex organisations

A mature, proactive working style with strong ownership of outcomes

Excellent communication skills and the political awareness to navigate a corporate environment Comfortable operating autonomously while keeping stakeholders aligned

Languages

English: Fluent (must)

Dutch or French: Fluent/proficient (must)

Why This Role

Long-term engagement with genuine architectural ownership - you set the direction, not just the diagrams

Hybrid working - 2 days per week in Brussels, remainder remote

Work at the intersection of established enterprise data (Informatica, DWH) and modern cloud platforms

A visible role with direct access to senior Business and IT stakeholders
