Terabase Energy, Inc. is a Berkeley, CA-based venture backed startup that was founded by solar industry veterans as a result of a technology spinout from SunPower Corporation in 2019.  Our mission is to accelerate the renewable energy transition by reducing soft costs and improving efficiency in the development, procurement and construction of large renewable energy projects.  We serve our global clients using technology we develop and are already working on some of the largest and most impactful solar powerplant projects in the world.

Job Description

Terabase Energy seeks a Senior Electrical Engineer with strong high voltage experience to support the development, design and implementation of high voltage substations and transmission lines for large-scale solar and energy storage projects globally. The Senior Electrical Engineer will interface directly with leading international solar developers, IPPs, EPC contractors and transmission system owners and operators. The Senior Electrical Engineer will report to the Director of Project Engineering and will be responsible for directly and indirectly managing junior engineers and designers.

The Terabase project engineering and consulting team provides technical services across a wide range of roles including technical consulting, owner’s engineer, contractor’s engineer and detailed engineering and design. As such, the Senior Electrical Engineer must be comfortable in supporting projects from varying perspectives. The candidate must be capable of managing a dynamic workload. These duties must often be performed with limited information, conflicting interests, on short time frames, and with limited oversight.

During the development phase of a project, the Senior Electrical Engineer will be responsible for supporting interconnection applications, running system models, and assisting in the preparation of RFP packages. This may include the preparation substation single lines and conceptual layouts, assisting in the siting of substations and route selection of gen-tie lines, preparing technical specifications for long lead equipment, and drafting technical requirements for substation and gen-tie line RFP bid packages. During the design and implementation stage of a project, the Senior Electrical Engineer will be responsible for preparing conceptual design packages, preparing equipment specifications, providing technical reviews of substation design deliverables, attending factory acceptance tests for major equipment, and performing site visits during construction and commissioning. The Senior Electrical Engineer will also be responsible for coordinating with other engineering disciplines as well as with the engineering teams executing the solar and energy storage facility designs.​
