Requirements
• 5+ years of product management experience, with at least 2 years building API products, data platforms, or data distribution products at a B2B company • Experience designing APIs for external consumers: you have opinions on schema design, versioning strategies, rate limiting, and what makes developer documentation actually useful • Track record of shipping data products where you managed the full lifecycle: from defining what data to expose, through schema design, to commercial packaging and client onboarding • Understanding of data infrastructure concepts: data pipelines, warehouses, ETL/ELT, data modelling, and platforms like Snowflake • Comfortable with SQL and capable of interrogating data to validate quality, understand usage patterns, and inform product decisions • Experience working in a solution-selling or partner-led GTM model: you have been involved in POCs, pilots, or co-development with enterprise clients, not just self-serve product launches • Proven ability to lead cross-functionally without a dedicated team: you coordinate across engineering, data, and commercial functions through influence, not authority • Strong commercial instinct: you understand how enterprise data buyers evaluate providers, and you can shape a product that competes on data quality, coverage, and ease of integration • Clear communicator who can translate between technical and commercial audiences • Familiarity with credit markets, debt instruments, or how buy-side/sell-side firms consume financial data • Experience with Snowflake data sharing, marketplace listings, or similar cloud data distribution mechanisms • Experience building entitlements, licensing, or access control systems for data products • Understanding of data licensing, redistribution terms, or AI usage policies in the context of enterprise data products • Hands-on experience with Python for data exploration, prototyping, or working with engineering teams
Responsibilities
• PRODUCT STRATEGY & EXECUTION • Define the product vision and strategy for 9fin's external data distribution: REST APIs, Snowflake data shares, and future delivery mechanisms (cloud sync, pub/sub). • Own the data catalogue decisions: which datasets to expose, in what format, through which channels, and in what order, balancing client demand, data readiness, and commercial potential • Design the developer experience end-to-end: API design, documentation, developer portal, sandbox/playground, authentication, error handling, rate limiting, and versioning • Work with analytics engineering and domain teams to define schemas, data models, and transformation logic that make 9fin's data consumable and valuable outside the application • Use a partner model to validate early: select and work closely with 1-2 clients during development to co-develop and prove out each data product before broader launch • Shape the commercial model for API products: packaging, tiering, usage-based pricing, distribution controls, and entitlement structures that capture the value of programmatic data access • DATA QUALITY, INFRASTRUCTURE & COMPLIANCE • Partner with the Head of AnalyticsData and analytics engineering to ensure data products meet the reliability, freshness, and accuracy standards that enterprise clients building automated systems expect • Define SLAs for data delivery (latency, uptime, completeness) and build the monitoring and metering infrastructure to back them up • Own the entitlements and access control layer: ensuring the right clients can access the right data under the right contractual terms, with appropriate usage limits and controls • Work with Legal to define data usage policies, including restrictions on redistribution, AI training and model embedding, and onward use, protecting 9fin's data IP while enabling legitimate client workflows • Establish feedback loops between API consumers and domain teams so that usage patterns and client requests improve the underlying data over time • CROSS-FUNCTIONAL LEADERSHIP & GTM • Coordinate across platform engineering, analytics engineering, domain squads, and the Head of Data to align priorities and ship a cohesive product without a dedicated squad • Influence teams you do not manage; build relationships that make cross-functional delivery work despite competing priorities • Support the shift to a solution-selling GTM motion: work with Sales and Customer Success on partner selection, POC design, technical onboarding, and commercial structuring for API deals • Engage directly with enterprise clients and their technical teams during pilots and integrations; this is a client-facing role, not a back-office one • Communicate strategy, progress, and trade-offs transparently to leadership, engineering, and commercial teams • Translate technical API and data infrastructure concepts into language that non-technical stakeholders (Sales, Legal, Finance) can act on
Benefits
• Competitive, market-benchmarked salary • Pension with 7% company matching • Private medical insurance, paid sick leave, income protection, group life assurance • Season ticket and cycle-to-work schemes • Hybrid flexibility with up to 3 months annual work abroad • 25 holiday days plus local public holidays (exchangeable) • One-month paid sabbatical after 5 years; enhanced parental leave • Professional development budget and regular social events • 9fin is an equal opportunities employer
