Data Analyst in London

The Company Capital Markets Gateway LLC (CMG) is a capital markets-focused fintech transforming global equity capital markets (ECM) through data, technology, and connectivity. As the preferred source for ECM analytics and the first network connecting the buy-side and sell-side for ECM workflows, we are committed to reshaping how capital markets operate. Founded in 2017 by a team of ECM practitioners, CMG has completed three successful fundraising rounds and is backed by a group of the world's most prestigious financial institutions. The CMG platform is currently relied upon by nearly 150 buy-side firms representing $40 trillion in AUM and 22 global investment banks.

The Role: CMG works with some of the world's largest and most complex financial institutions. In this role, you will be central to onboarding and supporting these clients by owning and continuously improving the master client reference database that connects them to CMG's platform. You will ensure that client entities, identifiers, and attributes are accurately captured, quality controlled, and consistently linked across multiple data sources and tenants. This includes identifying data quality issues, reconciling inconsistencies, and establishing clear relationships between related records to create a reliable "source of truth." Where data is incomplete or outdated, you will proactively coordinate with internal stakeholders and external client contacts to obtain updated client forms and reference information, ensuring the platform remains current and compliant. Your work will be critical to maintaining data accuracy, consistency, and usability across clients directly impacting platform stability, onboarding efficiency, and the overall client experience.

Our Team: The CMG Enterprise Solutions Team is responsible for onboarding our clients and delivering a world-class experience in our products. At the core of our application sits Rolodex – the database that connects our clients together. This is operated, curated, and managed by the Client Data Team within Solutions.

Responsibilities:

• Own client data collection, databases, processes, and pipelines
• Design processes that improve data quality and data governance
• Resolve complex integration challenges across multiple client systems
• Diagnose and address live client issues with speed and accuracy

Qualifications: You are a detail‐oriented, analytical problem solver with strong technical and data management skills who thrives in complex data environments. You enjoy working hands‐on with client reference data validating, normalizing, and maintaining its integrity across systems. You bring a structured, quality‐first mindset to data, ensuring accuracy, completeness, and consistency at scale. You are comfortable establishing and maintaining relationships between disparate data sets, identifying gaps or discrepancies, and implementing processes to resolve them. You leverage automation, tooling, and emerging AI capabilities where appropriate, but you also understand when proactive human engagement is required—such as reaching out to clients to procure updated reference data and required forms. Your work directly enables reliable downstream analytics, platform functionality, and client trust.

• Taking ownership of large data sets and databases
