Data Analytics Engineer (CXT)

Description

Channel Data & Insights (CDI) is a core, crosscutting capability within Investec's Client Experience Technology division. CDI governs channel behavioural data across digital and assisted-servicing channels and turns that data into trusted data products, platform analytics and evidence. CDI complements Business Unit analytics by providing consistent cross-consumer comparability on shared experiences and shared-failure visibility across digital-to-assisted transitions.

Within this context, the Data Analytics Engineer is a hands‑on build role that bridges data engineering and data analytics. The role converts analyst‑owned product specifications into governed, certified and reusable data products on the Group data platform and owns the semantic modelling layer that makes shared experiences measurable and comparable across channels and business units.

The Data Analytics Engineer enables scale through reusable platform capability rather than bespoke analytics delivery. The role builds and maintains governed data products, analytical models and semantic layers that allow Business Unit Analytics teams to self‑serve trusted insight using consistent definitions, reusable patterns and certified data foundations.

Key Responsibilities

• Data Product Engineering Design, build and maintain governed data products on the Group data platform, including bronze, silver and gold layers, reusable data marts and certified analytical data products.
• Analytical & Semantic Modelling Define and maintain semantic models, star schemas, KPI logic and behavioural entities such as events, sessions, journeys, flows, steps, intents and transitions. Maintain definition consistency across channels and business units.
• Data Quality, Contracts & Conformance Implement validation checks, testing frameworks, data contracts, governance controls and certification evidence so that data product quality is demonstrated rather than assumed.
• Insight Delivery & Platform Analytics Build analytical products and Power BI assets that support descriptive, diagnostic, predictive and prescriptive analytics over governed data products.
• Enablement & Self‑Service Create reusable datasets, templates, onboarding material, usage guidance and playbooks so that consuming analytics teams can use the data products without re‑engineering the foundations.
• AI‑Enabled & Conversational Analytics Structure datasets and semantic models so that AI agents, conversational analytics and natural language querying return accurate outputs against governed business logic and definitions.
• Automation, Engineering Practice & Operations Use Python, SQL, Azure DevOps, Git and CI/CD practices to automate analytics delivery, version control solutions and support performance monitoring and optimisation of owned products.
• Partnership & Technical Leadership Partner with analyst product owners, platform engineers, Business Unit Analytics and Business Unit Digital / Technology teams to translate requirements into technically sound, reusable and governed implementations.

Qualifications, Experience and Skills

• Strong SQL and Python, including data transformation, analysis, automation and reusable component development.
• Working knowledge of Microsoft Fabric, Databricks, Delta, Spark / PySpark, Azure Data Factory, Synapse, ADLS Gen2 and event or streaming patterns.
• Dimensional modelling and semantic modelling expertise, including Kimball star schema design, data marts, Power BI semantic models and DAX.
• Practical understanding of data governance, Microsoft Purview, Unity Catalog, data contracts, data quality, testing, lineage and certification.
• Azure DevOps, Git, CI/CD and infrastructure as code exposure.
• Bachelors or Masters in Computer Science/Engineering
