At DEXMA, we’re applying cutting edge technologies to one of the world’s greatest challenges: efficient energy management. Our customers give us billions of energy usage data measurements, which we analyze and aggregate. With our platform we help companies reduce energy consumption, be more efficient, and generate savings.

Our product DEXCell Energy Manager is a distributed system composed of dozens of modules, written mostly in Java and Python, and using backends such as RabbitMQ, Storm, PostgreSQL, Redis, MongoDB and our public REST API. All these tools allow DEXMA to develop one of the European TOP 5 Energy Management Softwares.

We’re now hiring a frontend developer who can deliver outstanding output, in a start-up environment using Agile methodologies. Developers have the freedom to come up with new feature ideas and work closely with product managers & user experience designers to make an impact on the millions of users in letgo community.
