FTSE Russell (LSEG) is transforming how Sustainable Investment (SI) data is gathered, managed, and delivered — building modern platforms that power index and data products used globally. We're looking for a hands-on Senior Product Manager to own the end-to-end product lifecycle for our Sustainable Investment data platforms — from onboarding new data sources through to migration, delivery, and ongoing optimisation. This is a delivery-focused product role, where you'll define the roadmap, work closely with engineering and operations, and ensure high-quality, reliable data products that meet both client and regulatory expectations.

• Define and own the product roadmap for SI data gathering, management, and distribution platforms.
• Own onboarding and lifecycle of data sources, from discovery and evaluation through to production readiness.
• Lead migration of datasets and workflows from legacy systems to strategic data platforms.
• Partner with engineering, operations, and commercial product teams to deliver scalable, reliable data capabilities.
• Drive data quality, coverage, and timeliness, ensuring products meet client and regulatory requirements.

WHAT YOU'LL BRING:

• 10+ years of relevant work experience in data product ownership / technology / business analysis / operations / application delivery in banking or financial domain.
• Exposure to commercial product and operations teams in the financial industry, ideally linked to Indexing/Funds.
• Experience with Sustainable data vendors and products (i.e. ESG indicators and scores, climate, carbon emissions, green revenues).
• Proven ability to take new data sources from discovery to production (source evaluation, data mapping, ingestion patterns, validation rules, change management, and operational handover).
• Experience leading migration of datasets from legacy systems to target data platforms (e.g. cloud/data lake/warehouse), including data mapping, transformation design, reconciliation, parallel run strategies, and cutover planning to ensure data integrity and minimal business disruption.
• Familiarity with data management and artificial intelligence applications in a business context.
• Experience with Sustainable Investment / ESG data.
• Exposure to index, market data, or financial data products.
• Familiarity with data platforms (cloud, lakehouse, or warehouse) in a product context.
