Data Governance & Data Quality Consultant

Job Description

Ever wondered what it feels like to be a Data Governance & Data Quality Consultant (Mid-Senior) at Netcompany?

Joining us as a Data Governance & Data Quality Consultant (Mid-Senior), you will play a key role in defining, designing, and overseeing data governance and data quality frameworks, helping organisations establish trusted data assets, improve data management practices, and ensure the accuracy, consistency, and reliability of their data.

Working at the intersection of data management, business requirements, and technology, you will take ownership of governance definitions, business glossaries, critical data elements, and data quality rules. You will collaborate closely with Data Engineers and client stakeholders, translating business needs into clear functional specifications and ensuring that technical implementations deliver accurate, meaningful, and measurable results.

As a key consulting partner for our clients, you will contribute to presenting solutions, explaining governance concepts, validating technical deliverables, and ensuring effective collaboration between business and technical teams.

As a Data Governance & Data Quality Consultant (Mid-Senior), you will:

• Manage business glossaries and metadata: Define and maintain business glossary terms, including descriptions, source references, custom attributes, and Critical Data Elements (CDEs), using enterprise data governance platforms.
• Advise on data access and permissions: Provide guidance on access management and governance structures, with an understanding of role-based access control (RBAC), permissions, and access management principles across cloud environments.
• Design and oversee data quality frameworks: Define data quality dimensions, identify Critical Data Elements, establish validation rules, determine quality metrics and acceptance thresholds, and ensure that the defined rules accurately reflect business requirements.
• Validate data quality implementations: Review SQL queries developed by Data Engineers to verify their logic and ensure that implemented rules correctly measure the intended data quality requirements. Identify inconsistencies, provide documented feedback, and coordinate necessary improvements.
• Monitor data quality results: Navigate relevant data management and analytics environments to access, review, and interpret data quality results, identify potential data management issues, and assess the overall quality of enterprise data.
• Review and assess data inputs: Examine client-provided files, definitions, and business requirements to assess their accuracy and completeness, and map them against existing data quality rules to avoid duplication or conflicting definitions.
• Engage with client stakeholders: Present data governance concepts, data architecture, and proposed solutions during project kick-offs and throughout project delivery. Act as a key point of contact for discussions concerning business definitions, data quality rules, and results.
• Coordinate project activities: Work closely with the Project Manager and Data Engineers to monitor deliverables, organise workflows, facilitate communication between stakeholders, and ensure smooth project execution.
• Drive continuous improvement: Identify opportunities to improve governance practices, data quality frameworks, documentation, and the overall management and reliability of enterprise data.
