Senior Process Development Engineer

As a Senior Process Development Engineer, you design, scale, and optimize manufacturing processes — taking a product from lab-scale prototype to full production. You develop process parameters, design experiments to optimize yield and quality, troubleshoot process issues, and transfer processes from development to manufacturing. The senior title means you're leading process development projects and making critical decisions about process design.

Your day blends laboratory work with production floor reality. You might run a designed experiment to optimize a reaction yield, then analyze the data to determine optimal parameters, then write a process description for technology transfer, then work with manufacturing to troubleshoot a quality issue on the production line. You need strong engineering fundamentals, statistical analysis skills (DOE, SPC), and the practical knowledge to know when lab results will and won't translate to production scale.

Scaling is the central challenge. A process that works perfectly in a 1-liter flask may fail at 10,000 liters. Heat transfer, mixing, material handling, and countless other factors change with scale. Your expertise is understanding these scale-dependent effects and designing processes that work reliably at production volumes.
