Qualifications

• Proven experience leading, building and mentoring a team of architects or senior technical staff.

• Collaborate with key stakeholders to identify and prioritize the most valuable data products and outcomes.
• Lead the strategy and execution for migrating away from the current centralized data warehouse and operational data store model toward a distributed, data product-based architecture.
• Ensure data domains and assets are clearly structured, connected and aligned across the organisation, avoiding duplication, conflicting definitions, and siloed solutions.
• Partner with business stakeholders to understand decision-making needs and translate these into scalable, outcome-driven data domain designs.
• Work closely with engineering and platform teams to guide implementation, ensuring alignment with enterprise platforms (e.g. Snowflake), integration patterns, and data cataloguing requirements.
• Establish and promote standards for data modelling, data product design, and interoperability, enabling consistency across federated domain teams while supporting flexibility where needed.
• Set clear technical governance for the architecture team, ensuring decisions balance innovation with pragmatism and align with business outcomes.
• Contribute to and help shape our data strategy and roadmap, embedding architectural considerations that support long-term scalability and value.
• Represent data architecture in senior technology and business forums, building alignment and buy-in for the data mesh transition.
