About Storio

Storio Energy offers energy storage solutions to businesses in France around 2 use cases :

• Solar panels + battery : the battery boosts the self-consumption rate, providing greater autonomy and resilience.
• Standalone battery for electro-intensive clients : the battery charges when electricity prices are low to make its energy available when prices are high, enabling ~20% savings.

We want to enable a world 100% powered by low-carbon energy at an affordable price. We do this by helping our clients come out as winners of the ongoing energy transition. This also means improving the competitiveness and resilience of industrials companies and pushing them towards a greater electrification and decarbonization of their activity.

Our energy management software controls batteries in real-time to maximize the savings on our customer’s bills and to generate additional revenues by stabilizing the electric grid. Providing ancillary services using batteries that are installed on customer sites is new in France and definitely hard to do : we’re the pioneers of B2B energy storage in France and many challenges lie ahead of us!

We provide a turnkey service, working with our clients from initial feasibility studies, to purchasing the batteries, installing them on site, and operating them seamlessly using our software platform during the 15+ years of operations.

Storio raised a 5M€ seed round from Lowercarbon Capital (global #1 climate tech fund) and Bpifrance. Our team gathers experts from Tesla, EDF Renewables, NW Group, Agregio Solutions, repeat entrepreneurs from the AI space, and experienced software engineers.

The opportunity

We’re a growing team of around a dozen, and we’re looking for a new Software Engineer to design and build the real-time server-side and embedded control systems to operate the batteries deployed by Storio.
