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 WebForms admin tools, and CI/CD pipelines that are being modernised. You won’t write code, but you’ll need to be comfortable in this environment to make strong product decisions.

What’s on offer

Private health insurance and employee assistance

25 days' holiday

One day a week working from home, adaptable hours, and up to four weeks a year from another location

Learning and development support

An international team with a startup mindset, building a brand‑new office
