Master Data Manager

City, London
Hydrogen Group

We are seeking an experienced Senior Market Data Manager to take ownership of our global market data and research vendor portfolio following the merger of two organisations.

This is a high-impact role responsible for managing, negotiating and optimising hundreds of third-party data and research contracts, including enterprise agreements with providers such as Bloomberg, FactSet and Morningstar.

The successful candidate will lead a structured consolidation and governance programme, ensuring cost optimisation, regulatory compliance and appropriate data coverage for investment and research teams. This is not a policy or oversight role, we are looking for a hands-on commercial expert who will directly lead negotiations and execution.

Key Responsibilities

• Market Data & Vendor Management
• Own and manage the full portfolio of market data and research vendor contracts (ranging from small research agreements to multi-million-pound enterprise contracts).
• Lead commercial negotiations with major vendors.
• Drive contract renewals, benchmarking and cost optimisation initiatives.
• Develop strong working relationships with key providers and internal stakeholders.
• Governance & Control
• Establish clear governance frameworks for market data procurement and usage.
• Ensure regulatory compliance and audit readiness.
• Implement structured renewal cycles and BAU processes post-consolidation.
• Improve transparency and reporting across data spend and usage.
• Post-Merger Consolidation
• Untangle and rationalise overlapping contracts following organisational merger.
• Identify duplication, inefficiencies and optimisation opportunities.
• Deliver a structured roadmap for consolidation and long-term management.
• Stakeholder Engagement
• Partner with Investment, Research, Risk, Compliance and Technology teams.
• Balance commercial efficiency with business data requirements.
• Act as the central point of expertise for market data strategy.

Required Experience

• Extensive experience managing market data vendor relationships within asset management, investment management, wealth management or financial services.
• Proven track record negotiating with major providers such as Bloomberg and FactSet.
• Experience managing large contract portfolios (including enterprise-level agreements).
• Strong commercial acumen and negotiation capability.
• Experience operating within regulated financial environments.
• Demonstrated ability to implement governance frameworks and structured renewal processes.

Preferred Experience

• Experience supporting or leading post-merger data consolidation.
• Familiarity with usage analytics and optimisation tools.
• Exposure to procurement best practices in financial services.
• Experience managing renewal cycles for major enterprise agreements.

Candidate Profile

• Commercially astute and confident negotiator.
• Hands-on and delivery-focused – not purely strategic.
• Able to operate independently and take ownership.
• Strong stakeholder management skills.
