Job Description

At FreeWire we fundamentally change the way businesses and utilities electrify. We build battery-based energy storage systems that provide clean and quiet power anywhere it’s needed, reducing the cost and accelerating deployment of electric vehicle charging infrastructure. FreeWire’s solutions are evolving from providing ultrafast EV charging services to a full suite of energy services to accelerate sustainable electrification and provide resiliency to customers and a distributed power source to utilities. FreeWire has secured major strategic investors from Fortune 100 companies and serves leading corporate, utility, and retail customers. The feedback on the Boost Charger, FreeWire’s DC fast charger, has been overwhelmingly positive as we electrify locations that would have been too expensive to power on using conventional charging solutions. Utilities are releasing RFPs with requests for battery backed solutions, their regulatory teams are including our technology as eligible for incentives, and they are seeking cost effective solutions as they electrify their fleets and provide utility owned charging solutions for the public.

FreeWire has deployed battery-integrated chargers with Fortune 100 companies, commercial customers, fleets, retail locations, and gas stations. In addition to its partnership with bp pulse, FreeWire and ampm, a bp subsidiary and convenience store chain with over 1,000 locations, have already deployed multiple public charging stations in the U.S. FreeWire’s regulatory affairs and policy team keeps customers up to date on federal, state, and utility incentive opportunities, which in some cases cover up to 80% of the cost of the charging station, and the company recently announced that the Boost Charger is Buy America compliant.
