Our client is one of Europe's leading asset managers. It has a global presence and runs active, passive and alternative investment strategies for clients worldwide.

It is now building a new technology hub in Madrid. The hub will deliver full end-to-end technology for the whole group worldwide. It is not a satellite or support office. Over the next 18 months it will grow to 40-60 technologists, working in areas such as Architecture, Data Platforms, Artificial Intelligence and Investment Technology.

The company is modernizing its technology and prefers to build its own tools rather than buy SaaS products. It is looking for technologists first: you don't need a background in finance, as you'll learn the domain on the job.

If you join now, you'll be part of the hub from its early days. You'll help shape how the teams are organized and how technology decisions are made in Madrid.

You'll join the Investment Risk technology team and lead the UI work on its modernization program. You'll work in a collaborative, international team. Your job will be to turn complex risk workflows into clean, intuitive and scalable interfaces.

• Work with business analysts, product stakeholders, developers, testers and architects to turn complex requirements into user-friendly solutions.

• Work with the backend team on Java / Spring services (API design, integration, troubleshooting and end-to-end validation).

• Take part in the full delivery lifecycle: refinement, design, development, code reviews, testing, releases and post-release improvements.
