Objective
Data powers price-intelligence, BOM optimisation, and excess-inventory trades for the Global electronics supply chain. Your mission is to safeguard the truthfulness and business relevance of every dataset we provide; spotting hidden anomalies, reconciling multi-source price feeds, and ensuring each metric we publish can be trusted by procurement, finance, and compliance teams of our customers.
Key Responsibilities
End-to-End Data Validation :
- Trace each data item, from customs records and supplier catalogues through ELT transforms to the customer dashboard, verifying completeness, accuracy, timeliness, and lineage.
- Define acceptance criteria and golden datasets for complex calculations such as landed-cost, tariff duty, lifecycle risk scores, and alternate-part price floors.
- Draft and execute detailed test plans that reflect real-world supply-chain scenarios : non-standard UOM shipments, multi-currency quotes, EOL announcements, QC failures, compliance flags, etc.
- Challenge business rules like, import-value thresholds, MOQ rounding, tariff/ tax treatments, by creating boundary and negative test cases.
- Use SQL, Mongo queries and ClickHouse queries to profile data distributions, identify outliers, and reconcile divergent prices across regions (IN, SEA, CN, US, EU, etc).
- Produce investigative reports for anomalies (spikes, missing batches, unit-of-measure mismatches) and drive root-cause resolution with Data Eng and Product Delivery teams.
- Maintain a living Data-Quality Specification that maps every metric to source tables, transformation logic, and business meaning.
- Conduct UAT sessions with supply-chain analysts and sourcing managers; capture feedback, raise defects, and sign off releases.
- Own data-quality SLAs and report status in weekly engineering reviews.
- Where automation adds clear value, introduce light-weight scripted checks (Great Expectations, custom SQL assertions) and embed them in CI.
- Mentor developers on writing testable SQL/ELT models and documenting edge cases.
- 4+ years in data-centric QA, business-analysis, or data-engineering roles with a heavy validation component.
- Deep domain knowledge of electronic components, MPN nomenclature, tariff/HS codes, landed-cost structures, lifecycle statuses (Active, NRND, EOL), supply chain risks and commodity compliances.
- Strong SQL/ NoSQL skills for ad-hoc investigation and reconciliation across MongoDB or PostgreSQL or ClickHouse; comfort with queries, joins, etc.
- Practical experience validating multi-source price feeds, currency conversions, and time-series data.
- Demonstrated ability to translate business rules into precise test cases and to communicate findings clearly to both engineers and non-technical stakeholders.
- Meticulous attention to detail and an instinct for questioning numbers that look right but feel wrong.
- Familiarity with Great Expectations for declarative data testing.
- Exposure to supply-chain or ERP data (SAP, Oracle, QAD) and EDI/CSV ingestion quirks.
- Basic scripting in Python for one-off data probes and small automation hooks.
- ISTQB (Advanced) or equivalent certification focused on data quality.
