The Financial Information division within SIX Group is a global provider of financial data and analytics to the global financial services industry. This role sits within the Business-led Product Development division and focuses on business data architecture, ensuring our financial data products meet customer, commercial, and regulatory needs. The role partners closely with IT Architecture as a key stakeholder but is not part of the IT function.
We are looking for an experienced data architect to work within the Financial Information Product Delivery group to provide data architecture leadership across the firm to ensure our data products deliver value to our customers and they can be readily maintained and enhanced. This encompasses the design and architecture of logical and physical data models and schemas, data transport mechanisms, metadata management, lineage management, API schema design, and enabling SIX financial information to be accessible to AI agents.
What You Will Do
- Design, develop, and maintain the technology-agnostic, business-aligned canonical/conceptual data models for Financial Information, defining class definitions, standards, and association semantics.
- Provide data architecture expertise to all delivery teams to ensure we build data products that meet customer expectations, can be readily maintained and enhanced, and we have a core foundation on which we can readily build new revenue-generating products.
- Develop and maintain design, naming conventions, dictionaries, lineage, and metadata standards, collaborating with data quality teams to ensure models support validation rules.
- Partner with stakeholders across the business to translate complex data concepts and requirements into robust data products that customers want to purchase whilst contributing to the architectural governance process.
- Support the evolution of data distribution models, including API-first delivery and AI data access enablement.
