Company Overview

Zeno Power’s (Zeno) mission is to provide clean, plug-and-play power anywhere in the universe. To do that, Zeno is developing a next-generation radioisotope power system (RPS) that generates carbon-free, resilient power for decades, utilizing material found in nuclear waste. Zeno’s technology is both light-weight and cost-effective compared to historic RPS, opening up broad market opportunities in space and terrestrially. To bring this breakthrough technology to market, Zeno is seeking out purpose-driven and innovative professionals who are comfortable working in a startup environment.
