Test Data Developer

We are seeking a hands-on Test Data Developer with strong Qlik Data Integration / Qlik Replicate experience to support the delivery of enterprise test data solutions across multiple non-production environments.

This role is responsible for translating the Test Data Strategy into practical, repeatable data provisioning solutions. The successful candidate will design, build, maintain, and support Qlik-based replication and integration pipelines that deliver production-representative data into lower environments for testing purposes.

In addition to strategic delivery, the role will own a stream of business-as-usual (BAU) test data requests, including environment refreshes, dataset creation, defect resolution, and small enhancements. The individual will work under the guidance of the Technical Lead while managing day-to-day delivery independently.

What You’ll Be Doing:

• Test Data Provisioning & Automation
  • Design and implement test data provisioning solutions using Qlik Replicate and related Qlik Data Integration tools.
  • Configure and support full-load and Change Data Capture (CDC) replication tasks.
  • Provision production-like data into non-production environments while maintaining data quality and integrity.
  • Build reusable and scalable data provisioning patterns across projects and environments.
  • Implement data filtering, subsetting, and transformation rules to ensure datasets are fit-for-purpose and appropriately sized.
  • Monitor replication performance, latency, completeness, and overall task health.
  • Troubleshoot replication failures, schema changes, connectivity issues, and source-to-target discrepancies.
• Data Governance & Security
  • Apply agreed masking and obfuscation processes to sensitive and personal information.
  • Ensure compliance with data privacy, security, and environment management standards.
  • Maintain auditability and evidence of masking controls and provisioning activities.
  • Ensure no unapproved movement of production data into lower environments.
• BAU Support
  • Manage a steady flow of test data requests, including:
    • Environment refreshes
    • One-off data extracts
    • Data defects
    • Small enhancements
    • User requests
  • Assess whether requests should be delivered via:
    • A tactical/manual solution; or
    • A reusable solution within the Qlik capability.
  • Provide impact assessments, effort estimates, status updates, and appropriate handover documentation.
  • Continuously identify opportunities to convert tactical fixes into sustainable platform-based solutions.
• Collaboration
• Work closely with:
  • Test Teams
  • Environment Management Teams
  • Database Administrators
  • Source System Owners
  • Security and Data Governance Teams
  • Technical Leads
• Provide guidance to testing teams on data availability, readiness, refresh schedules, and coverage limitations.
• Contribute to operational documentation, runbooks, standards, and reusable templates.
