- Understanding of data integration, workflow orchestration and distributed systems.
- A pragmatic, analytical approach to complex engineering challenges.
- Strong communication skills and the ability to influence technical and business stakeholders.
- Fluency in English (C1 or better); Spanish is advantageous.
- Experience in energy or trading is welcome, but not essential.

You’ll join a small, ambitious team with the freedom to move quickly, make decisions and create lasting impact. If you want to shape the foundations of a modern technology and data landscape, we’d like to hear from you.
