About the position
At ESS (NYSE: GWH), our mission is to accelerate global decarbonization by providing safe, sustainable, long-duration energy storage that powers people, communities, and businesses with clean, renewable energy anytime and anywhere it's needed. As more renewable energy is added to the grid, long-duration energy storage is essential to providing the reliability and resiliency we need when the sun is not shining and the wind is not blowing. Our technology uses earth-abundant iron, salt, and water to deliver environmentally safe solutions capable of providing up to 12 hours of flexible energy capacity for commercial and utility-scale energy storage applications. Established in 2011, ESS Inc. enables project developers, independent power producers, utilities, and other large energy users to deploy reliable, sustainable long-duration energy storage solutions. As the Manufacturing Engineer I, you will specialize in the electrical and power systems within our manufacturing processes. You will work collaboratively with cross-functional teams to design, validate, and implement robust manufacturing processes and equipment, ensuring they meet the high standards of scalability and reliability required for our energy storage solutions.
