Senior Fullstack Developer

Who we are

The electricity grid is central to society, and it's under more pressure than ever. Electric vehicle charging, heat pumps, solar panels and new developments: society is in the middle of our energy transition, and grid operators need a data driven support.

At Endre, we've built a Digital Societal Twin, a full replica of society that gives grid companies and property developers the visibility, intelligence and forecasting power to make smarter and faster decisions. Our customers use our software to spot bottlenecks before they become crises, model long-term demand scenarios, and manage the flood of new grid connection requests. The work is technically challenging, the impact is tangible, and the team is small enough that you will contribute directly to the product from day one.

You don't need to be an expert in every layer, but be comfortable across the stack, with a strength in frontend. As a tech company we are also at the forefront when it comes to using new tech, and expect that you are experienced in and comfortable using AI development tools.
