Business Analyst QA

Own the requirements-to-acceptance chain for the Entity Hub. This is a combined role: define what correct” means for entity resolution and graph outputs, then prove it through structured testing. The position is pivotal because milestone payments are released against acceptance criteria — this role writes them, traces them and validates against them.

• 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.
