Madrid | Full-time, permanent | Hybrid (3 days on-site)

Socium is supporting one of Europe's leading providers of market data and financial software as they grow their new tech hub in Madrid. The hub opened this summer and already has around 30 people. This is a chance to join early and help shape the team and the office culture, with an established international business behind you.

The role
You will own a next-generation entitlement and access control platform that sits at the centre of the company's Fintech product ecosystem. It manages product and market data entitlements, permissions, licensing and provisioning across internal and external systems. The squad has a clear mandate to modernise the platform, improve reliability and bring in a modern engineering approach.

What you'll do
• Own the product vision, roadmap and backlog for the platform
• Act as the technical authority on entitlement behaviour, data flows and integrations
• Prioritise work across stability, scalability, compliance and modernisation
• Write precise,



testable acceptance criteria and keep the backlog well groomed
• Make trade-off decisions between short-term delivery and long-term product health
• Work with other Product Owners on migrations, cross-system needs and finance/back-office integration

What we're looking for
• Several years as a Technical Product Owner or Product Manager on backend, data or platform products (not a first PO role, and not a front-end/digital product background)
• A strong grasp of service-oriented architectures, APIs, and data-heavy, rules-driven systems
• Experience modernising legacy platforms incrementally in an Agile environment
• Confidence discussing design, trade-offs and risk with senior engineers
• Nice to have: entitlement, licensing or access-control experience, exposure to financial services or market data, scrum master experience

Tech environment
C#, .NET Framework 4.8, MS SQL Server (complex schema, stored procedures, ETL), WPF and ASP.NET WebFo
