2 About position
The company specializes in trading energy products on European energy exchanges, supported by a proprietary in-house trading platform, analytical tools, and advanced models.
Rather than developing solutions for external customers, it focuses exclusively on creating technologies that empower its trading teams to make better, faster, and more informed decisions.
This approach allows the company to prioritize innovation without the constraints of competing client requirements, externally imposed deadlines, or UI/UX-driven design.
Its work spans a wide range of technical challenges, from data collection and trader dashboards to sophisticated trading platforms and fully automated trading systems.
The tech stack: Both frontend and backend are written in Scala, which means that we can share non-trivial logic between both sides easily and implement communication protocols as needed, instead of being stuck with usual solutions that never really fit.
