What we’re looking for
- Bachelor’s degree or higher in Chemistry, Biology, or related field
- NO LESS THAN 3 years of hands-on LC-MS experience (more for Principal level)

Additional insight
This is not a highly structured, task-by-task role. The team is still building, and the right candidate will be someone who can work autonomously, take initiative, and operate effectively without needing day-to-day direction.
