Mechanical Engineer, Cell Stack Design

Electroflow Technologies is revolutionizing the battery supply chain using sustainable electrochemistry. In the last year, we invented our breakthrough electrochemical lithium extraction technology, scaled it 1000x, and validated it on real brine samples acquired from across the US. We’re supported by the Breakthrough Energy Fellowship and leading climate investors. Come join us as we fully unlock America’s battery potential! We're seeking motivated individuals eager to tackle chemical, electrochemical, and engineering challenges.

We are hiring a Mechanical Engineer to construct our next-generation electrochemical cell stack. The ideal candidate will possess knowledge of computer aided design (CAD), 3D printing, and stack tolerance analysis. The candidate will design, develop, test, and validate critical stack components such as flow plates, endplates, seals, and bipolar plates while ensuring alignment with stack performance targets. They will also analyze and optimize compression settings to ensure robust sealing performance and uniform compression under various operating conditions.

Requirements

• Bachelor’s degree in Mechanical Engineering or related field

• At least 3 years of applied engineering experience in industrial or academic settings
• Experience in stack tolerance analysis and design validation
