The Input Trait Discovery group, located in Johnston, IA, has an exciting opportunity for a Mass Spectrometry & Proteomics Lead, to develop and apply analytical mass-spectrometry & proteomics methodologies towards identifying unique protein targets to support our discovery pipeline for insecticidal actives.


As part of the group, you will be a key research contributor, play a critical role and be embedded in cross-functional teams for the implementation and development of mass spectrometry-based assays critical to our protein discovery efforts. Your scientific expertise and knowledge will be relied upon to provide strategy and solutions towards solving complex protein identification challenges.


This role presents a great opportunity to be a player-coach, supervising employees while demonstrating hands-on experience in protein identification and protein quantification by LC/MSMS, nano-LC/MSMS and computational proteomics analysis.




  • Provide mass-spectrometry and proteomics support to various research projects within the Input Traits Discovery group with emphasis on protein identification and protein quantification.
  • Work with other members of the group to establish analytical tools and assays appropriate for each research project, monitor research progress, identify and resolve scientific/technical challenges impacting projects in a timely manner.
  • Provide management, scientific leadership and creativity when initiating, designing, and executing assay development across a wide range of projects.
  • Serve as a subject matter expert with current knowledge of the field and make recommendations on new analytical techniques and state-of-the art instrumentations that could positively impact the discovery pipeline
  • Operate and maintain the mass spectrometry laboratory and associated instrumentation. Coordinate with instrument service engineers for scheduled maintenance and timely repairs.
  • Maintain and expand internal protein databases which are used to assist protein purification and identification.
