About Photoncycle Photoncycle is reimagining the energy landscape by delivering energy as a service. We build, install, own, and operate distributed energy storage systems, together with the digital infrastructure needed to scale as an aggregator and electricity provider across European markets. Our mission is to accelerate the transition to a more renewable, balanced, and secure energy system. Photoncycle systems combine solar energy, long-duration storage, and energy trading, so households can use homegrown energy year-round for electricity, heat, and hot water, while also helping the grid balance production and consumption peaks. This enables the transition away from fossil-based energy for households. Our software platform is critical to that mission. It supports the digital services, fleet operations, and market capabilities required to operate Photoncycle systems safely, efficiently, and at scale. We are 25 employees with offices in Oslo and Copenhagen. In 2026 we raised a €15 million Series A led by NordicNinja and Voima Ventures, and joined by Lifeline Ventures, Luminar Ventures, Momentum Partners, and Eviny Ventures. We are now moving from full-scale pilot to commercial rollout, and the first phase of our production plant is underway. The Role We are looking for a Product-Minded Software Engineer to help design and implement core backend software for Photoncycle’s next-generation energy platform. You’ll start by contributing to the team building our core energy platform software, and grow into adjacent product and business domains as the platform expands. This role is primarily focused on backend development in C#/.NET. You’ll help build the software that represents, monitors, and interacts with deployed Photoncycle systems in the field, including telemetry, communication with units, operational health checks, and diagnostic data retrieval. Much of this space is still unbuilt. You'll spend as much time prototyping, exploring, and testing ideas as shipping f
