What are the responsibilities and job description for the Data Architect and Data Modeller position at Riverflex?
DATA ARCHITECT / DATA MODELLER
Interim / Freelance | On-site (Amsterdam) | 16 weeks option to extend
Our client, a leading real estate services organisation operating across Continental Europe, is building a shared, standardised data model to harmonise how core business concepts — properties, assets, parties, transactions, leases and valuations — are understood across countries and systems. You join a lean, senior team to design that model and the principles for connecting existing local data to it.
This is a deep, hands-on modelling role. You define the conceptual and logical data model, separate the shared "common core" from country- and business-line-specific extensions, and design the mapping patterns that let existing local data systems connect to the new shared layer.
About Riverflex Riverflex was founded in Amsterdam and London in 2018, eventually growing into a global team of consultants united by a mission to help courageous leaders drive transformative change. Today, we offer an integrated service through three service pillars: strategy and transformation consulting that Creates Change, talent services that Build Teams, and business-accelerating products that Augment Intelligence. For more information, visit www.riverflex.com.
Responsibilities
Define the conceptual and logical data model, including core domains, entities, attributes and relationships.
Separate shared enterprise semantics from country-, sector- and business-line-specific extensions.
Design local-to-central mapping principles, data standards and controlled extension patterns.
Establish ownership, quality, lineage, metadata and model change-control approaches with the team.
Translate the model into physical design principles and inputs for the data engineering backlog.
Work with country and business-line stakeholders to validate the model and drive adoption.
Job requirements
Strong hands-on data modelling and data architecture experience (conceptual, logical and physical).
Semantic modelling expertise — ontologies, knowledge graphs, Linked Data (e.g. RDF, SHACL) and related tooling.
Experience with Domain-Driven Design and defining a semantic layer over multiple source systems.
Grounding in data governance and data management practice (e.g. DAMA / CDMP-style frameworks).
A structured, transparent communication style; comfortable bridging business goals and technical execution across distributed teams.
EU work authorisation.
The following are a plus:
Experience harmonising data models across multiple countries or business units.
Real estate, financial services or other asset/transaction-heavy domain exposure.
Why this role
You design the semantic backbone that a major European organisation will build on for years. It's rare, high-leverage modelling work — defining the shared language for an entire continent's data, with senior autonomy and a lean expert team around you.
