Sr Research Associate, Protein Purification (Job Number: 196940W-01)


We are looking for a Senior Research Associate to join our protein discovery team. The primary responsibilities will be to purify and characterize biologic molecules from diverse sources to support novel protein discovery. Proteins will be purified at scales ranging from high-throughput robotic miniaturized purifications to gram quantity processes to support commercialization pipeline. Additionally, the new team member will be expected to learn cell culture methods to express proteins, and extensive bioanalytical techniques.

The ideal candidate will be somebody who wants to contribute to a protein discovery team. They will not be satisfied by simply doing their part. Instead, they will interact daily with their colleagues who provide them research materials and with others to whom they deliver purified proteins to conduct experiments. The process is collaborative and affords a great opportunity to learn many facets of protein discovery.
