A fixed‑term intern will support a targeted migration of the organisation’s main Power BI semantic model to a more efficient refresh and preparation pattern by moving existing transformation logic into Dataflows (Gen2 where available) and aligning the approach to Microsoft Fabric ways of working (capacity, One Lake, and governed work spaces). The aim is to achieve a like‑for‑like migration (not a redesign): reduce refresh time and failures, simplify supportability, and produce clear documentation and handover materials.

This opportunity is offered as a Fixed‑Term Contract of 3 months.

• Migrate existing data preparation steps out of the semantic model and into governed dataflows, maintaining the same business outcomes and KPI results.
• Adopt Fabric‑aligned patterns where available (for example, using Dataflows Gen2 and consistent landing/curation conventions), improving operational support and lineage.
• Improve refresh reliability and performance by standardising refresh configuration, reducing duplicated transformations, and enabling clearer troubleshooting.
• Deliver a cutover‑ready package: documentation, validation evidence, and a rollout plan the core team can execute safely.

• Baseline the current semantic model refresh process: sources, transformation steps, refresh duration, failure modes, and dependency mapping.
• Create a migration plan identifying which queries/tables will move to dataflows first (staging then curated), including naming, folders, and ownership.
• Build and validate Dataflows (Gen2 where available), including parameterisation, refresh schedules, and gateway configuration if required; align work spaces to Fabric governance and capacity constraints.
• Update the existing semantic model to consume the dataflow…
