Executive and Operations Assistant

About Arcturus Arcturus is building a new kind of electrical conductor technology to help modernize the systems that power our lives. We believe better materials can unlock a very real impact in the world around us: lower-cost electrification, a stronger and more resilient grid, and infrastructure that can carry more power with less waste. This kind of improvement has the potential to help reduce over 500M tonnes of CO2 emissions, lower the risk of catastrophic wildfires by enabling safer and more capable transmission infrastructure, and make it cheaper and easier to deliver electricity where people need it most. At the end of the day, we’re building Arcturus because we think the physical backbone of energy transmission matters. We can make that backbone stronger, more efficient, more scalable, and directly help improve the lives of millions of people.
