Product Engineer (m/f/x)

Job description

01 · Why this role exists Invest in Values. Produce in Freedom. Boost Europe. Europe can reindustrialise if we bring AI, energy market opportunities and industrial processes together. Europe's largest industrial companies, together around 2% of Europe's total energy demand, already make their energy decisions with RIZMO, the AI agent in our Energy OS at RIZM. As Product Engineer you build that product. You decide what we build and ship it to real industrial sites, with short feedback loops straight from the customer. No ticket queue.
