Test Facility Engineer

Operations Lancaster, California

Position at Heliogen

The Company:

Heliogen is a clean energy company focused on eliminating the need for fossil fuels in all sectors of the economy. Heliogen’s mission is to create the world’s first technology that can commercially replace fossil fuels in industrial processes with carbon-free, ultra-high temperature heat from the sun and to transform sunlight into fuels, including hydrogen, at scale. Heliogen was created at Idealab, the leading technology incubator.

Position Purpose:

The Test Facility Engineer will be responsible for the testing and evaluations done at the Heliogen Lancaster test site as well as maintenance and operation of the site itself. As Heliogen develops new systems and equipment (heliostats, receivers, reactors, and associated items) for its concentrated solar projects, the Test Facility Engineer will lead the integration of that additional equipment into the Lancaster facility. The Lancaster test site includes permanent installations of a heliostat field (of Heliogen’s proprietary design), a tower for concentrated solar receiver testing, and three buildings which include a control room, workshop areas, and a conference/ educational area for interactions with customers, investors, and the public. The Test Facility Engineer would have the Lancaster facility as their normal base of operations and work location. The Test Facility Engineer will interface with various external contractors and Heliogen personnel as equipment deployment and testing is done.  The Test Facility Engineer would have full time support from a small number of additional Heliogen personnel based in Lancaster.
