• Engineer automated data quality pipelines that detect, diagnose, and remediate data defects; design for scalability, idempotency, and observability.
• Use Python/SQL for data profiling, rule evaluation, schema validation, anomaly detection, and automated exception workflows.
• Implement API-driven integrations (REST/Graph
  
  QL/SDKs) with DQ, catalog, ticketing, notification, and orchestration systems; handle OAuth2, pagination, rate limits, retries, and backoff.
• Define and maintain DQ rule libraries and validation frameworks as reusable, versioned assets; enforce code quality via unit tests, linting, and static analysis.
• Embed automated controls into ETL/ELT and data integration jobs; implement pre/post load validations, row/column level checks, and SLA/SLO monitoring.
• Build event driven alerts and webhook workflows to route exceptions to the right queues (e.g., Jira/Service Now), with metadata for reproducibility and audit.
• Develop KPI dashboards and operations apps using Power BI and Power Apps to visualize coverage, drift, and rule performance, and to streamline triage/remediation.
• Conduct root cause analysis using lineage, logs, and metrics; implement automated remediation where feasible (e.g., rollback, quarantine, replay).
• Contribute to CI/CD workflows (Git Lab or equivalent) for DQ assets: automated tests, environment promotion, secrets management, and change controls.
• Author and maintain runbooks, design docs, and operational playbooks; mentor analysts on scripting, APIs, and engineering best practices.
• Uphold risk, regulatory, and internal control requirements; ensure auditability and traceability throughout DQ processes.
• Perform other duties as assigned.

The ideal candidate is fluent in Python and SQL, experienced with REST/Graph

QL APIs, and comfortable integrating DQ checks into ETL/ELT, CI/CD, and event driven architectures.

• Bachelor's degree and a minimum of 5 years related experience; or in lieu of a degree, a combined minimum of 9 years higher education and/or work experience, including a minimum of 5 years related experience.
• Advanced proficiency in Python and SQL for automation, including building reusable libraries, scheduled jobs, and validation pipelines.
• API engineering experience: designing and consuming REST/Graph
  
  QL APIs, handling auth (OAuth2/Bearer), pagination, rate limits, error handling/retries, and webhooks for event-driven processes.
• Experience building solutions with Power BI and Power Apps for operational reporting and workflow automation.
• Demonstrated success collaborating across engineering, governance, and business teams in fast paced environments.

• Experience with automated ETL/ELT validation and data integration platforms; familiarity with pre/post load checks, data contracts, and schema enforcement.
• Proficiency with DQ/observability platforms (e.g., Informatica Cloud DQ, Monte Carlo, Anomalo, Collibra OwlDQ) and their SDKs/APIs.
• Hands on data profiling, rule design, and automated measurement of DQ dimensions (completeness, validity, accuracy, timeliness, uniqueness, consistency).
• Implemented governance aligned DQ frameworks (standards, metadata contracts, lineage, policy as code).
• Experience with workflow/automation tools (Power Apps, Alteryx, or equivalent) and messaging/queueing for event driven triage.
• Cloud experience (Azure, Snowflake): scripting with providers/SDKs, secrets management, job orchestration, and cost aware design.
• CI/CD in Git Lab (or similar): pipeline design, automated testing, code scanning, environment promotion, and approvals.
• Exposure to AI/ML based anomaly detection or statistical monitoring; ability to integrate model outputs via APIs.
• Excellent communication skills; able to explain engineering decisions and automation tradeoffs to non technical stakeholders.
• Proven ability to manage multiple concurrent automation initiatives and deliver high quality solutions on schedule.
