Quality Analyst

Key Responsibilities

• Requirements & traceability — elicit, document and baseline functional and data requirements across ingestion, canonical model, entity resolution and graph serving; maintain a Requirement Traceability Matrix (RTM) from requirement through to test evidence.
• Acceptance criteria ownership — translate SOW stage acceptance criteria into testable, measurable conditions; secure WK agreement on match-quality measures (precision/recall) and NLQ scenarios before build begins.
• Test strategy & planning — define the overall test strategy, quality gates, entry/exit criteria and test data approach for each milestone.
• Data quality validation — design and execute tests for data completeness, accuracy, transformation logic, standardization rules and identifier-spine integrity across all six sources.
• Entity resolution validation — build and curate labelled/golden validation samples; evaluate match precision, recall and false-positive rates; validate clustering and Golden Record survivorship logic.
• Graph validation — test node and edge accuracy, source traceability, and multi-hop traversal scenarios against expected paths.
• Human-in-the-loop coordination — operate and coordinate the SME review workflow, manage the review queue, capture reviewer decisions and feed them back as training/tuning input.
• Defect management — log, triage and track defects with reproducible steps; drive root-cause analysis on data discrepancies; maintain severity classification and closure evidence.
• UAT & sign-off — plan and coordinate user acceptance testing with WK SMEs; assemble milestone acceptance packs and secure written sign-off within the agreed review window.

Required Skills & Experience

Skill Area

Specific Requirements

Business Analysis

Requirements elicitation, user stories, functional specifications, RTM, data dictionaries, source-to-target mapping documentation

QA / Testing

Test strategy, test planning, test case design, regression suites, UAT coordination, defect lifecycle management

Data Testing

Advanced SQL for reconciliation, source-to-target validation, aggregation and business-rule testing, data integrity and constraint checks

Platform

Microsoft Fabric (Lakehouse, Delta tables, pipelines), OneLake, SQL analytics endpoints

Domain (advantageous)

Entity/master data concepts, match precision & recall, data quality dimensions, corporate hierarchy and ownership data

Tools

Test management platforms (QTest/Jira/ADO), Excel, Postman for API validation, Power BI for validation reporting

Soft Skills

Client-facing communication, stakeholder facilitation, precision in written acceptance language, structured escalation

Must-Have Qualifications

• 6+ years combined Business Analysis and QA experience on data platform or data warehouse programmes
• Demonstrable experience writing acceptance criteria that were used for formal client sign-off
• Strong SQL — able to independently write reconciliation and validation queries
• Experience maintaining a Requirement Traceability Matrix on a regulated or enterprise client engagement
• Experience coordinating UAT with external client stakeholders

Nice-to-Have

• Exposure to entity resolution, MDM or data-matching projects
• Familiarity with Microsoft Fabric or Azure data services
• Understanding of graph data structures (nodes, edges, traversal)
• Experience with statistical quality measures (precision, recall, F1)

Key Deliverables Owned

• Requirement Traceability Matrix (RTM)
• Test Strategy, Test Plans, Test Scenarios and Test Cases
• Entity resolution evaluation results and match-quality reports
• Node/edge accuracy validation evidence
• Defect log, RCA reports and closure evidence
• UAT sign-off and milestone acceptance packs

Dual Role / Complementary Skills

This is already a deliberate dual role (BA + QA). The pairing is intentional: the person who defines acceptance criteria is best placed to test against them, creating a tight traceability loop and removing hand-off ambiguity. Complementary overflow: this role can absorb a portion of project-coordination and documentation work alongside the Project Manager (who is at 75% FTE).
