Area of Work:
Join our technology team and help shape one of the most impactful systems in the European energy market — the M7 XBID trading platform, enabling pan‑European cross‑zonal intraday power trading.
Depending on your strengths, this position can be tailored as a back‑end, front‑end, or full‑stack role. We welcome candidates who excel in one specialization and want to contribute to a high‑performance, mission‑critical trading platform.
Your Responsibilities:
As part of our engineering team, you will contribute to designing, building, and evolving components of our platform. Your exact focus will depend on your skills and preferences:
If you focus on back‑end development, you may:
Design, develop, and maintain highly performant services in Java/Kotlin.
Work with Spring Framework and SQL databases (PostgreSQL preferred).
Contribute to messaging/event‑driven systems and high‑performance communication layers.
Lead technical initiatives and drive architectural evolution.
Debug and resolve complex issues across distributed systems.
If you focus on front‑end development, you may:
Develop responsive, robust front‑end interfaces for our trading platform.
Work with HTML, CSS, JavaScript, and modern frameworks (e.g., React).
Integrate front‑end components with real‑time APIs and WebSocket‑based data streams.
Collaborate closely with UX/UI and product teams to refine user‑centric features.
If you prefer full‑stack responsibilities, you may combine both:
Build end‑to‑end features from design to production deployment.
Ensure seamless integration of client‑side and server‑side components.
Own full lifecycle improvements across the entire stack.
