- Evaluate and recommend appropriate data storage patterns (relational, dimensional, lakehouse, graph)
Data Integration
- Architect and oversee data pipelines and ETL/ELT processes across source systems
- Design integration patterns for batch, near-real-time, and streaming data flows
- Ensure robust data lineage, traceability, and auditability across all pipelines
- Collaborate with engineering teams to implement scalable, resilient integration solutions
Analytics Enablement
- Develop semantic and analytical data models that serve BI, reporting, and advanced analytics use cases
- Partner with analytics and data science teams to define trusted data products
- Champion a self-service data culture by enabling reusable, well-documented data assets
Governance & Quality

- Communicate complex data architecture decisions clearly to both technical and non-technical audiences
Qualifications
Required Skills & Experience
Essential
- 5+ years of experience in data architecture, data engineering, or a closely related role
- Strong proficiency in data modelling techniques: relational, dimensional (Kimball/Inmon), and Data Vault
- Hands-on experience with data integration tools and frameworks (e.g. Apache Kafka, dbt, Spark, Talend, or similar)
- Solid understanding of cloud data platforms (AWS, GCP, or Azure) and modern data stack components
- Advanced SQL skills and familiarity with Python or Scala for data engineering tasks
- Proven ability to translate business requirements into scalable data architecture solutions
Preferred
- Prior exposure to event-driven architectures or real-time data platforms
- Experience working in agile, value-stream-aligned product organisations

- Knowledge of data governance frameworks and metadata management tools (e.g. Collibra, Alation, DataHub)
- Experience with analytical tools such as Looker, Tableau, Power BI, or Metabase
What We're Looking For
The ideal candidate brings both technical depth and cross-functional communication skills. You are comfortable moving between high-level architectural design and hands-on implementation. You thrive in collaborative, fast-paced environments and enjoy working across teams to solve complex data challenges. You bring a product mindset to data — treating data as an asset that must be reliable, discoverable, and useful.
