Job requirementsKey Responsibilities Logic Discovery and Requirements Analysis

• Work with pricing analysts to identify custom definitions, calculations, transformations, dependencies, assumptions, edge cases, and ambiguities currently implemented in the Gold layer.

• Reverse-engineer analyst-written SQL, spreadsheet logic, and ad hoc calculations to define intended business behaviour.

• Translate legacy logic into transparent technical requirements and migration plans.

Migration to the Silver Layer

• Re-implement approved pricing definitions as governed, reusable, documented dbt models in the Silver layer.

• Follow data modelling, naming, testing, version control, and code review standards.

• Build maintainable, scalable, auditable models independent of undocumented analyst knowledge.

• Apply dbt tests for uniqueness, not-null, accepted values, relationships, and business rules.

Parity Validation and Quality Assurance

• Compare migrated Silver-layer results with existing Gold-layer outputs and resolve differences.





• Validate results across representative periods, segments, boundary conditions, and known exceptions.

• Confirm migrations only after parity review and pricing analyst approval.

Analyst Collaboration and Sign-Off

• Partner with pricing analysts to clarify calculations, confirm intended behaviour, and align on expected results.

• Lead walkthroughs and reviews; document analyst approval before retiring legacy definitions.

• Communicate risks, open questions, dependencies, and decisions to technical and business stakeholders.

Documentation and Lineage

• Document business meaning, calculation rules, assumptions, exceptions, source inputs, ownership, lineage, tests, and downstream consumers in dbt and Confluence.

• Ensure documentation enables future engineers and analysts to maintain logic without relying on the original analyst.

Gold-Layer Cleanup and Cutover

• Decommission ad hoc Gold-layer logic after the Silver replacemen
