About Voltus

Voltus is a leading company for Distributed Energy Resources (DERs). Our mission is to be the platform that fulfills the promise of the energy transition. The Voltus platform connects any DER to any energy market across the US and Canada, providing flexibility, reliability, and resilience to the grid while generating revenue for our partners.

We hire teammates who are bright, gritty, and good and who have a genuine passion for delivering a cleaner energy future and for working in a fast-paced, entrepreneurial environment. We are a remote and virtual company, distributed primarily across the US and Canada. Candidates must be authorized to work in the US or Canada without requiring sponsorship.

The Role

Voltus is hiring a Senior Engineer for our edge technology team. With thousands of units installed streaming data live to Voltus’s platform, our fleet of devices enable our customers to monitor their energy usage in real time, and allows Voltus to manage thousands of sites for participation in demand response programs.

This team is preparing an accelerated deployment of devices. We are looking for an experienced software engineer to help develop our cloud architecture and IoT fleet management solutions as well as improve and advance our device firmware. A successful candidate will not only possess the required experience and technical skills, but will also demonstrate awareness, empathy, intentionality, curiosity and a desire to be part of an open, collaborative, and psychologically-safe engineering culture.
