We are looking for a Data Governance Consultant / Lea d to embed enterprise-grade governance, data trust, and robust stewardship practices into complex, secure data environments.

Master Data Solutions: Support MDM initiatives by mapping core domain entities, setting match/merge logic, and embedding clear data approval workflows.

Stewardship Enablement: Coach and mentor emerging domain data stewards on operational policies, standard operating procedures, and compliant data consumption.

What You’ll Bring

Demonstrated success architecting and delivering pragmatic governance strategies tailored to specific operational and commercial realities.

Proven ability to translate abstract compliance and governance principles into measurable business value.

Strong consultative and communication skills, comfortable guiding both executive stakeholders and technical data teams.
