The successful candidate will ensure that our identity platform consistently meets quality, compliance, and operational standards.

Develop automated contract and compliance checks , including schema validation, required fields mapping, TCF/consent validation, and PII‑risk checks aligned to governance requirements. Build and execute automated end‑to‑end API tests using tools such as Bruno, Insomnia, or Postman, validating API behaviour through API Gateway, Lambda integrations, and downstream data/graph operations. Build data quality monitors (nulls/ranges, volume deltas, distribution checks) and statistical tests suited to identity clusters; operationalize them as part of routine runs. Drift detection and score distribution monitoring for identity resolution outcomes; alerting on behavioural/statistical shifts. Consent and governance checks that mirror operational policies (e.g., consent‑only processing at node/edge level, version‑controlled thresholds). Prior testing experience with identity resolution / data science / probabilistic systems —including calibration/threshold validation and explainability. Familiarity with observability (alerts, dashboards) to uphold guardrails on performance, resilience, and cost visibility.
