Technical Support Engineer​/Field Engineer

Community Energy Labs (CEL) is looking for a California based Technical Support Engineer / Field Engineer to help deliver our innovative, money- and carbon-saving solutions to our customers. In this role, you’ll be a main point of contact for our customers, supporting site integrations, troubleshooting, debugging, and onboarding of new sites, both remotely and on-site. You’ll also collaborate closely with our product and engineering team to improve our technology and customer experience.

The role is about 75% customer operations and technical support and 25% field engineering. Occasional travel is required (especially in spring and summer) for site visits, installation and troubleshooting. If your colleagues describe you as disciplined, organized, and a great communicator of technical information then we want to hear from you.

Community Energy Labs enables buildings to use energy when clean sources of power are available and to use less energy overall by making smart decisions about when and how energy is used. We primarily work with communities and schools, whose buildings make up nearly 30% of the commercial floor space in the US!

Community Energy Labs, its employees, and its customers are driven to be a part of the solution to saving our planet. Our software combines cutting edge control algorithms, machine learning, and traditional control techniques to lower cost and manage energy. We combine that with an intuitive user interface that doesn’t require a PhD in mechanical engineering to make saving money and the planet easy for everyone - even cash‑strapped schools with overworked building operators.
