Website Plus Power

Company Overview 

Plus Power is an energy storage market leader, with a market-leading 10+ GW portfolio across more than 25 US states and Canadian provinces that will transform North American electric grids into cleaner and more versatile critical infrastructure.

Standalone energy storage is rapidly transforming the North American energy markets, because it is cheaper than new natural gas plants, faster to build than fossil peakers or transmission, and able to perform diverse energy services. Plus Power partners with electricity system operators, utilities, and investors to originate, develop, finance, own and operate standalone energy storage projects that provide critical services to the wholesale electric market. Plus Power’s team applies an intentional mindset to energy storage development by using a data-driven approach to development and operations.

At Plus Power, we are focused on solving hard climate problems, profitably.  We are growing fast, and value candidates who, like us, share a focus on setting high expectations, owning and learning from mistakes in the spirit of radical transparency, and are committed to internal partnering as a key element of our ideas meritocracy. Our team praises Plus Power’s culture and excels through our game-changing mission and supportive ecosystem.

About the Role 

Plus Power recruits outstanding energy industry professionals who are driven to develop, build and operate assets safely and reliably to decarbonize the power markets while growing their careers. Our team looks for data-driven and fact-based mindsets, engaging and collaborative behaviors, and personal growth-focused professionals.

In order for the global energy system to make the transition from a carbon-based grid, to a renewable energy grid, large scale energy storage must be introduced into the electricity system to balance intra-hour supply and demand. Energy storage is the enabler of high penetration variable renewable generation like solar and wind.

Plus Power is looking to hire a creative, driven and experienced Principal Optimization Engineer for the development and enhancement of a real-time energy trading platform for grid-scale battery energy storage systems (BESS). The successful candidate will play a critical role in shaping our company’s technology direction and be hands-on in building and deploying high-performance, scalable, and resilient systems.
