About the Position

We are seeking a talented Senior Data Modeller - Analytical Solutions to lead the design of enterprise-scale analytical Data Vault 2.0 models for a data platform built on Databricks.

In this role, you will define shared analytical models and standards that ensure consistency, reusability, and trust across the enterprise. This position offers a unique opportunity to lead the architectural transformation of a complex legacy environment into a streamlined, future-ready data asset, while building a versatile profile to drive data strategy across any modern cloud environment.

Responsibilities

• Model enterprise-level analytical Data Vault 2.0 structures on Databricks, handling both structured and semi-structured data

• Establish modeling patterns suitable for lakehouse, medallion, and semantic-layer architectures
• Ensure alignment between physical analytical models and enterprise semantic definitions
• Act as the primary interface between business stakeholders and data engineering, focusing strictly on data modeling rather than hands-on engineering
• Translate complex business logic into high-quality documentation, data lineage, and precise models for engineering implementation
• Conduct deep-dive sessions to audit and remediate complex or poorly structured data assets in the current environment
• Establish enterprise data modeling standards that prioritize data integrity, portability, and long-term flexibility
• Lead data profiling activities to ensure physical implementations align with defined data models

Requirements

• 5+ years of dedicated experience in data modelling (not deep hands-on engineering)
• Hands-on experience with modern cloud data platforms (Databricks)
• Strong experience with SQL. Familiarity with Python/PySpark is a plus
• Deep knowledge of modeling approaches such as Kimball, Inmon, and Data Vault 2.0, with the ability to select the most appropriate methodology to address specific business challenges
• Experience with enterprise-grade modelling tools (e.g., ER/Studio, Erwin, or Sparx EA)
• Strong soft skills and non-confrontational behavior

We Offer

• Projects for clients such as PayPal, Wargaming, Xerox, Philips, Adidas, and Toyota
• Competitive compensation that depends on your qualification and skills
• Career development system with clear skill qualifications
• Flexible working hours aligned to your schedule
• Corporate medical insurance covering services of private and public medical centers
• Corporate parties and events for employees and their children
