Mechanical Designer – Containerized Water Treatment Systems
About The Position
ZwitterCo is seeking an experienced Mechanical Designer to lead detailed design and layout development for standardized skidded and containerized water treatment systems (50–100 gpm range). This role is critical to transforming our container systems from project-based designs into a scalable, repeatable product platform. With support/guidance from the engineering team, the Designer will own 3D mechanical layouts, P&ID development and maintenance, container GA packages, fabrication drawing coordination, and standard design library development. This position directly supports schedule compression, platform standardization, and scalable growth. About ZwitterCo ZwitterCo has developed a breakthrough in materials science - a new class of zwitterionic membranes with unprecedented fouling resistance. Our membrane solutions perform beyond the limits of traditional filtration, making it practical to treat complex wastewater, purify water for reuse, and maximize efficiency in food processing applications. ZwitterCo serves customers in more than 20 countries across food and beverage, agricultural, and industrial sectors. We are rapidly investing in our technology, equipment, and global services platform to help our industrial customers achieve their most ambitious sustainability and growth targets. We are grateful to have been named as Fast Company’s Top Innovators of 2024 and featured on the 2025 & 2026 Global Cleantech 100.
