We orchestrate over 30'000 distributed energy sources such as batteries, electric vehicle chargers and solar inverters with the purpose of maximizing the value of renewable energy flexibility for users and grid and therefore enabling the success of the energy transition. /ppWe firmly believe that any asset must be able to join the orchestra and take part in a stable and affordable energy system, using renewable energy maximally and rewarding everyone equally good for their investments in renewables. /ppWe stand for sustainability, innovation, and carry high value for ownership and autonomy. /ph3We are looking for: /h3pWe are looking for an experiencedbsenior level Backend Engineer
- Platform IoT Integration /b, who will take ownership of core backend and integration systems across our platform. You combine deep technical skill with a generalist mindset: comfortable moving between application code, cloud infrastructure and device-level integration, and trusted by the team as the person to call when something breaks or a solid architectural decision is needed. /ph3Key
