About Moon FiveMoon Five helps multi-family homes unlock the full potential of their existing electrical infrastructure — starting with plug-and-play direct-to-tenant EV charging at $50/month and zero upfront costs.Moon Five’s hardware, software, and deployment optimizations allows us to skip the costly infrastructure upgrade and long installation cycles, enabling rapid EV charging adoption today while setting the stage for future energy services like load balancing, DERs, and affordable backup energy. Our system, called Horizon, consists of an EV charger, apartment energy management system, and building energy management system that measure the amount of current being used at an apartment and throttle the energy going to the charger to keep the apartment breaker from tripping.Moon Five is a Los Angeles Cleantech Incubator (LACI) portfolio company, and participated in Berkeley Skydeck, Creative Destruction Labs, and Cleantech Open and is an Energy Power Research Institute’s (EPRI) Incubatenergy Finalist.Job DescriptionWe are seeking a skilled Electrical Integration and Test (I&amp;T) engineer for a contract role for up to 40 hours a week on a 1-3 month contract.
