Join the Gaco team, a trusted name in building envelope solutions with a heritage dating back to 1955.

We’re seeking a Senior Process Engineer who’s ready to be part of a company committed to formulating everyday success for every customer through innovative, reliable products used to adhere, seal, and protect at every level of the building envelope.

We are seeking an experienced and highly motivated Process Project Engineer to both manage capital improvement projects and provide direct technical support to our manufacturing operations. The ideal candidate is a hands-on engineer with a strong background in chemical process environments. In addition to managing the entire project lifecycle—from scope definition to commissioning - this role will be a key technical resource for the site, responsible for driving continuous improvement by analyzing workflows, identifying bottlenecks, and optimizing existing processes to enhance safety, quality, and efficiency. This position requires a unique blend of technical engineering acumen, project management discipline, and a practical, plant-floor perspective.
