• Lead the architecture, optimisation, and operational management of the Snowflake data warehouse platform.

• Develop robust ELT/ETL pipelines to ingest, transform, and deliver high-quality data from multiple internal and external sources.

• Build reusable and maintainable data frameworks, transformation models, and orchestration workflows.

• Develop and maintain infrastructure-as-code and automation for data platform provisioning and management where appropriate.

• Optimise performance, scalability, and cost efficiency across data storage, transformation, and query workloads.

• Support near real-time and batch-based data processing requirements.

Snowflake Engineering & Optimisation

• Own and continuously improve Snowflake architecture, performance tuning, security, governance, and operational best practices.

• Design and optimise Snowflake schemas, warehouses, clustering strategies, and data sharing capabilities.

• Implement scalable data modelling approaches including dimensional modelling and data vault methodologies where appropriate.

• Manage Snowflake access controls, roles, permissions, and secure data sharing practices.

• Monitor Snowflake usage, query performance, and cost consumption to drive optimisation initiatives.

• Support data lifecycle management, retention, and governance policies within Snowflake.

Data Modelling & Analytics Enablement

• Design and maintain curated, trusted, and scalable data models to support analytics, reporting, and operational use cases.

• Partner with analysts, business stakeholders, and engineering teams to translate business requirements into scalable data solutions.

• Enable self-service analytics capabilities through well-structured semantic layers and governed datasets.

• Support and optimise BI and reporting platforms such as Looker, Power BI, or equivalent tools.

• Ensure data structures and models support both operational reporting and strategic analytics requirements.

Data Quality, Governance & Reliability

• Implement data quality controls, validation frameworks, reconciliation processes, and monitoring capabilities.

• Proactively identify and resolve data integrity, consistency, and performance issues.

• Establish observability and operational monitoring for data pipelines and platform reliability.

• Contribute to data governance, lineage, cataloguing, and metadata management practices.

• Ensure data platforms and engineering processes comply with security, privacy, and regulatory requirements.

Collaboration & Leadership

• Collaborate closely with Product, Engineering, Operations, Finance, and Business stakeholders to deliver impactful data solutions.

• Mentor and support junior engineers and analysts within the broader data function.

• Contribute to data engineering standards, best practices, and platform strategy.

• Drive continuous improvement initiatives across data architecture, tooling, and delivery practices.

• Work cross-functionally to improve organisational data literacy and data maturity.

Skills & Experience

Essential

• 5+ years of experience in Data Engineering, Analytics Engineering, or related data platform roles.

• Experience designing and supporting multi-region and enterprise-scale data platform architectures.

• Strong experience driving performance optimisation and cloud cost efficiency initiatives across large-scale data workloads.

• Strong understanding of platform reliability, operational maturity, resilience, and production support practices.

• Experience implementing advanced governance, security, access control, and data protection models within enterprise data platforms.
