- Ensure the architecture meets business and analytical needs, focusing on historical accuracy, traceability, data quality, and performance.
- Evaluate architectural alternatives and support critical technical decisions.
- Provide practical guidance on implementation planning and manage technical dependencies.
- Review and challenge architectural assumptions and technical choices to identify risks, gaps, alternatives, and trade-offs.
- Offer recommendations based on experience with comparable banking implementations.
- Act as a sparring partner to the existing technical leadership, fostering constructive challenge and knowledge sharing.
- Translate architecture into implementable solutions and participate in critical design reviews.
- Provide guidance during implementation phases and share lessons learned with the project team.
- Conduct independent architecture assessments, including risk evaluation and recommendation of alternatives.
- Contribute to the documentation of a clear, implementable data warehouse architecture.
- Support architecture decision-making by providing rationale for critical technical choices.

- Experience with modern data warehouse and lakehouse architectures, including SQL-based platforms, object storage, and managing historical data.
- Deep understanding of complex financial data requirements, including auditability, data lineage, and regulatory reporting.
- Ability to critically evaluate architectural alternatives balancing quality, complexity, cost, and delivery risks.
- Excellent communication skills with the ability to constructively challenge technical proposals.
- Hands-on implementation experience in banking environments, having delivered comparable solutions rather than providing only high-level architectural advice.

Preferred Qualifications and Benefits

- Experience acting as a trusted sparring partner to technical leadership teams.
- Proven ability to share relevant experience and lessons learned effectively with project teams.
- Demonstrated skill in providing recommendations grounded in previous banking implementations.
