#YourOpportunity

Deloitte is a worldwide leader in Professional Services with a presence in more than 150 countries and territories. Since 2018, Deloitte has been operating its Alexander Competence Center in Thessaloniki with satellites in the cities of Patras, Heraklion, and Ioannina - which are model hubs of expertise, training, and innovation, specializing in cutting-edge exponential technologies, in which graduates and young professionals undergo immersive experiences, continuous learning, gaining practical insights and hands-on training that empower them to navigate the complexities of the digital landscape.

Deloitte is an ideal working environment for both young and senior professionals who want to take the next step in their careers, offering them a supportive and international working environment that leverages their expertise and potential. Its corporate culture is based on trust and collaboration and ensures diversity and inclusion so that everyone feels part of a great team.

#AboutYourTeam

You will be part of the Global Delivery Network (GDN), supporting the AI Ready Market Data initiative for Deloitte Belgium.

You will report functionally to the Data Governance Lead for the initiative and work with Internal Knowledge Managers (quality assurance), ITS Data & Analytics (technical implementation), DRD stakeholders (retention and archival), and BU/Industry champions (practitioner engagement).

#AboutYourRole

As a Data Steward you will:

• Play a key role in a flagship initiative at the heart of Deloitte’s data and AI transformation; help build an AI-ready marketplace that will reshape how practitioners discover and reuse knowledge.
• Help shape enterprise governance by contributing operational insights that inform how Deloitte governs, curates, and activates market data—with visible impact on how teams work.
• Build in-demand skills in data governance, AI readiness, and knowledge management with mentorship and support from experienced leaders in a structured, supportive environment.
• Work in a global GDN environment, collaborating with diverse stakeholders across business, technology, and risk—developing valuable cross-functional expertise.
• Join at a formative moment where your ideas can still influence processes, standards, and ways of working; you won’t be inheriting legacy systems, but helping build something new.

#YourResponsibilities

• Contribute to day-to-day curation and lifecycle management of market data assets (proposals, qualifications, deliverables, thought leadership, methodologies, case studies) on KX/Solaria/Teams, ensuring they meet enterprise standards for quality, compliance, and AI readiness.
• Apply governance policies in practice by operationalizing CoRe cleansing standards, GDPR requirements, AI Act compliance, and client confidentiality rules into concrete curation workflows, checklists, and guidance that teams can follow.
• Ensure assets are high-quality, well-tagged, and AI-ready by helping establish and maintain metadata standards, taxonomy, tagging conventions, and contextual documentation that enable AI tools to discover and surface the right assets to practitioners.
• Coordinate across teams on asset identification, prioritization, cleansing, validation, and archival by working closely with BU/Industry champions, Internal Knowledge Managers, ITS Data & Analytics, and DRD stakeholders.
• Monitor quality and drive improvement by helping define and track quality KPIs (target ≥95%), conducting spot-checks and audits, identifying root causes of issues, and feeding improvement ideas into governance forums.
• Support practitioner adoption by creating clear guidance on how to nominate and use assets, answering curation questions, and gathering feedback to continuously improve the marketplace experience.

#RequiredSkills

Experience & Background

• University degree Information's Technology, Data and Analytics & Science or related field.
• 3–5 years of professional experience in data stewardship, knowledge management, information management, data governance, or a similar role.
• Demonstrated experience contributing to data curation, metadata management, or information lifecycle initiatives, ideally in a collaborative or matrix governance structure.
• Familiarity with enterprise platforms such as SharePoint, Teams, or similar collaboration and knowledge management systems.

Knowledge & Skills

• Good understanding of data lifecycle, metadata standards, taxonomy design, and data quality frameworks.
• Working knowledge of data privacy and information security concepts (e.g., GDPR); willingness to learn AI governance and Deloitte’s CoRe standards on the job.
• Strong analytical skills and attention to detail; you care about accuracy, completeness, and compliance.
• Excellent communication skills in English; Dutch and/or French is a plus for collaborating with Deloitte Belgium stakeholders.

Competencies

• Collaborative, structured, and pragmatic; you work effectively with both technical teams and business practitioners across organizational boundaries.
• Curious, learning-oriented, and keen to grow into greater ownership under guidance from senior data governance leaders; comfortable with ambiguity and change in a new initiative.
