Downstream Engineer III
About The Position
The Downstream Process Development Engineer III is responsible for supporting downstream biotherapeutics process development through hands-on purification and recovery experiments. In this individual contributor role, you will support process development across multiple scales, from micro scale through bench and pilot scale, and contribute to both early-stage and late-stage programs. You will work with more senior process engineers to plan and execute larger experiments, while also partnering with process development team members to generate data, maintain accurate records, and contribute to the development and optimization of downstream processes. As an Engineer III in downstream process development, you will contribute independently within established procedures, use sound judgment in routine problem solving, and support project delivery on schedule.
