And we’re counting on your unique voice and perspective to help EY become even better, too. Join us and build an exceptional experience for yourself, and a better working world for all.

At EY Global Delivery Services (GDS), we work hand in hand with the business to build awareness of our services and solutions; to bring our purpose — building a better working world — to life for our people, clients and communities; to engage our people and build a high performing culture; and to build the commercial value and emotional resonance of the EY and the GDS brand.

The opportunity

We have already established a data warehouse with foundational semantic models, which currently serves as the nucleus of our data integration landscape. Our next strategic step is to transform this foundation into a hybrid cloud architecture, combining on‑premises capabilities with modern cloud services to support scalability, performance, and advanced analytics.

As a Senior Data Integration Specialist, you will play a key role in:

• expanding and strengthening our existing data integration structures

• supporting the evolution toward a hybrid cloud–enabled Data Fabric

• improving the quality, connectivity, and usability of RM data across EY

• enabling global teams to make better, faster, and more reliable risk decisions

This role sits at the intersection of data modeling, integration, and business context — ideal for someone who enjoys connecting systems, structuring information, and shaping data foundations.

Your key responsibilities

• Enhance and extend the existing RM data warehouse and semantic models

• Integrate data from multiple internal systems to support RM reporting, analytics, and process automation

• Build and maintain data relationships, metadata, and documentation that provide clarity and consistency

• Support the development of hybrid cloud integration patterns and help operationalize them

• Collaborate with global RM teams to gather requirements and translate business concepts into semantic data structures

• Implement data quality checks, standardization rules, and validation logic

• Help shape the future Data Fabric approach through contributions to metadata management, taxonomy alignment, and integration design

• Provide stakeholders with clear explanations and guidance on data access, meaning, and usage

What success looks like (first 12 months)

• You have expanded integration coverage in the existing data warehouse

• You have contributed to the design and setup of hybrid cloud integration workflows

• Data quality and consistency in key RM processes show measurable improvement

• You’ve delivered new semantic models that enhance reporting and reduce manual work

• Stakeholders across regions actively use your structures and documentation

• You are a trusted partner for both business and technology teams in RM

Skills and attributes for success

• Strong analytical mindset and attention to detail

• Ability to translate business questions into structured data models

• Clear and confident communication with global stakeholders

• Curiosity to explore new tools, technologies, and integration approaches

• Collaborative approach and willingness to work across time zones

• Practical problem‑solving orientation — finding effective, workable solutions

To qualify for the role, you must have

• University degree in Informatics, Mathematics, Physics, Engineering, or a related field

• Experience working with data integration, data modelling, or data quality

• Understanding of how data supports business processes

• Familiarity with SQL and willingness to deepen your technical skillset

Ideally, you’ll also have

• Exposure to Python, C#, APIs, or ETL/ELT tooling

• Experience with hybrid cloud concepts (Azure, AWS, etc.) — or interest in learning

• Understanding of metadata management or semantic modeling

• Background in risk, compliance, or professional services (optional)
