Role Purpose
The Senior Data Engineer will support the migration of complex legacy SQL Server stored procedure logic into modular, governed and reusable data platform layers across Bronze, Silver and Gold.
This is a hands-on build and delivery role, not a design-only consulting role. Solution design, architecture decisions and modelling standards will be owned by the internal technical lead. The resource is expected to implement, test, validate, document and deliver agreed designs using Snowflake, dbt and Azure Data Factory.
The role requires genuine data engineering experience, not report support, dashboard development or light SQL analysis.

- Must have migrated or refactored SQL Server stored procedures, or similar legacy stored procedure logic, into modern data platform patterns such as Snowflake, Databricks, Microsoft Fabric or AWS/Azure-native data platforms.
- Must have hands-on experience building facts, dimensions, SCDs, incremental models and batch pipelines.
- Must be comfortable working from incomplete or complex legacy logic and converting it into clean, governed data models.
Core Responsibilities
- Analyse complex SQL Server stored procedures and identify embedded business rules.
- Convert procedural SQL logic into reusable Snowflake and dbt models.
- Build Bronze, Silver and Gold transformation layers.
- Build Kimball-style facts, dimensions and star schemas.
- Implement SCD Type 1 and Type 2 patterns.
- Build incremental, batch and CDC-style processing patterns.
- Build Azure Data Factory ingestion and orchestration pipelines.

- Support source-to-target mapping, reconciliation and data validation.
- Implement data quality checks and validation rules.
- Support deployment automation, Git and CI/CD processes.
- Maintain mandatory technical documentation covering lineage, transformation rules, reconciliation outcomes, deployment steps and handover notes.
- Work with the internal technical lead to follow engineering standards, naming standards and modelling patterns.

Must Not Be
The Candidate Must Not Be Primarily:
- a Power BI-only developer,
- a dashboard developer,
- a report support analyst,
- a production support-only resource,
- a manual tester,
- a business analyst with light SQL,
a SQL analyst who has not built pipelines or data models,
- someone who has only consumed facts/dimensions but not built them
- someone whose recent experience is mostly non-engineering BI work

Senior BI Analyst / Senior BI Developer ? Offshore / Vendor
Number of Resources - 1
Seniority - Senior
Primary Technology Stack
- Power BI
- Power BI semantic model
- DAX
- SQL
- Snowflake / dbt
- Snowflake Presentation layer
- Dimensional modelling
- Report migration
- Metric migration
Role Purpose
The Senior BI Analyst / Senior BI Developer will support reporting migration, semantic layer delivery and Snowflake/dbt Presentation layer build for the new platform.
The role will focus on Power BI semantic modelling, report migration, metric rationalisation, DAX review, SQL validation and alignment of reporting logic to the new Snowflake Gold and Presentation layers.
This is a
hands-on build and delivery role, not a visual-only Power BI role or design-only consulting role. BI architecture, metric ownership decisions and platform design will be owned by the internal technical lead. The resource is expected to build, test, validate, document and deliver agreed designs.
A key expectation is to help move heavy reusable calculations, duplicated measures and report-specific business logic out of Power BI and into Snowflake/dbt Presentation layer models where appropriate. Power BI should consume curated, semantic-ready Snowflake outputs rather than perform complex transformations in the report layer.
The candidate must understand semantic models, facts and dimensions, DAX, SQL validation and the difference between metrics that belong in:
- Power BI visuals,
- Power BI semantic model,
- Snowflake Gold layer,
- Snowflake Presentation layer,
dbt models.
This role sits between the
Snowflake/dbt Presentation layer and
Power BI. The resource must be able to build and validate reporting-ready SQL/dbt outputs, not only create Power BI visuals.
Minimum Experience Required
- Minimum 3+ years BI / analytics delivery experience.
- Minimum 2+ years Power BI experience.
- Minimum 2+ years semantic model experience.
- Minimum 3+ years SQL experience.
- Must have worked on at least one reporting migration or data platform migration project.
- Must have experience working with fact and dimension models.
- Must have experience validating report outputs against SQL / warehouse outputs.
- Must have experience rationalising measures, duplicated metrics and report logic.
- Must be able to build or contribute to reporting-ready Snowflake views/tables or dbt presentation models.
Core Responsibilities
- Build and maintain Power BI semantic models.
- Build and migrate Power BI reports and dashboards.
- Build or contribute to Snowflake Presentation layer tables/views required for Power BI reporting.
- Build or update dbt presentation models where reporting logic needs to be moved out of Power BI and into the data platform.
- Move reusable metrics, heavy calculations and duplicated report logic from Power BI into Snowflake Gold / Presentation / dbt layers where appropriate.
- Review existing report-level logic, DAX measures and business metrics.
- Identify which metrics should remain in Power BI and which should move into Snowflake Gold / Presentation / dbt layers.
- Work with data engineers to ensure Gold and Presentation layer models support reporting requirements.
- Validate semantic model and report outputs against Snowflake / dbt outputs.
- Build and optimise DAX measures where required.
Support report testing, UAT and defect resolution.
- Support row-level security and reporting security patterns.
- Work with data engineers to ensure dbt models are deployed and orchestrated correctly through the agreed ADF / dbt run process.
- Support Power BI connectivity to Snowflake Presentation outputs, including agreed Import, DirectQuery or composite model patterns where required.
- Document semantic model relationships, metric definitions, DAX logic, validation outcomes and handover notes.
- Support Power BI performance optimisation and report migration clean-up.
Core Technical Skills Required
The candidate must have strong hands-on delivery experience across
Power BI, semantic modelling, DAX, SQL, Snowflake/dbt and dimensional reporting models.

- dbt model.
Migration / Metric Rationalisation
- Experience migrating reports from legacy platforms or legacy semantic models.
