    Current Open Positions


    Analytical Instrumentation Engineer


    IonDX has an opening for a full-time mechanical engineer who will guide the progression of our life science analytical instruments through final development and early manufacturing. Are you ready to take charge and solve highly technical problems? We need an engineer who will advance our concepts and convert our prototype testing results into a user-friendly platform technology. Do you want to work and grow with internationally recognized experts and become highly visible because you are inventive? Together, we will cut years off the biotech drug development cycle and speed the production of biotherapeutics and vaccines.


    IonDX™ is an early-stage company focused on commercializing our patented analytical instruments. Our first product is IMgenius™, a bench-top Ion Mobility spectrometer that is used to characterize biotherapeutics and gene therapy products. Our technology is revolutionary because it rapidly quantifies the conformation of large molecules. Users of our instruments are spread across all phases of biotherapeutic drug development, manufacturing and product release.
