Join a high-impact technology team shaping the software and data infrastructure behind critical energy and trading processes. As a Backend Engineer / Platform Engineer, you’ll help build reliable, scalable services that connect applications, data and infrastructure across the organisation.

This is a hands-on opportunity for an experienced backend engineer who enjoys solving complex problems, designing pragmatic solutions and working across the boundaries of software engineering, data platforms and cloud infrastructure.

What you’ll do :

• Build and evolve backend services, APIs and platform tooling used by data and engineering teams.
• Design robust integration and ingestion services connecting applications, systems and storage.
• Develop performant data models and scalable, resilient storage solutions.
• Improve data quality, observability, lineage and platform reliability.
• Translate business needs into clear technical designs and sustainable solutions.
• Work closely with infrastructure teams on cloud environments, provisioning and maintenance.
• Collaborate with stakeholders across technology and the business to deliver meaningful outcomes.

What you bring :

• 7+ years of professional software engineering experience.

• Experience with cloud infrastructure and services, ideally Azure.
• Practical knowledge of Kubernetes, CI/CD and modern DevOps practices.
• Working experience with databases, preferably PostgreSQL.
• 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.

Please note - the role is Hybrid and would potentially demand 2 days per week from the Central Madrid offices.
