SENIOR PARTICLE CHEMIST
GEORGETOWN, TEXAS
Quanterix is a company that is digitizing biomarker analysis with the goal of advancing the science of precision health. The company's ultra-sensitive detection solution, Simoa, has the potential to change the way in which healthcare is provided today by giving researchers the ability to closely examine the role of biomarkers in the continuum of health to disease. Quanterix' technology is designed to enable much earlier disease detection, better prognosis and precise treatment methods to improve the quality of life and longevity of the population for generations to come. The technology is currently being used for research applications in several therapeutic areas, including oncology, neurology, cardiology, inflammation and infectious disease.
ROLE SUMMARY:
We are looking for an experienced and highly motivated synthetic bead chemist to join our microsphere production and R&D team based in Georgetown, Texas. This role will support all microsphere production, research and development, and implementation of large-scale processing of multiple varieties of beads. The ideal candidate will also have experience in developing novel surface chemistries, coatings, and fluorescent molecule integration as well as magnetic material synthesis.
WHAT YOU'LL DO:


  • Work with other team members to synthesize large scale magnetic microspheres for use in the company's instrumentation. Additionally, you will carry out bench scale synthesis of experimental formulations independently.
  • Apply your experience in a production environment to carefully follow and fully document procedures and protocols.
  • Apply your experience integrating fluorescent molecules into a variety of latex microspheres.
  • Synthesize superparamagnetic metal oxides.
  • Prepare reagents, solutions, and carry out various distillation and recrystallization methods.
  • Apply experience troubleshooting and identifying synthesis related issues common to micro and nano particle production.


BASIC QUALIFICATIONS:


  • B.S. in Chemistry
  • 9+ years of experience in dispersion and emulsion polymerization, seeded and otherwise, of polystyrene (based) microspheres.
  • Experience in full scale synthesis of microspheres under GMP.
  • Experience integrating fluorescent molecules into microspheres.


PREFERRED QUALIFICATIONS:


  • Experience in seeded emulsion polymerization methods, especially crosslinked microsphere synthesis in the size range of 2-25 microns.
  • Experience in the fabrication of magnetic nanoparticles, especially magnetite synthesis and more specifically superparamagnetic iron oxide synthesis of well-defined and size-controlled crystals.
  • Experience developing polymeric coatings with specific surface chemistries and the ability to develop novel surface chemistries as needed independently. Examples include carboxylate, amine, and cyano moieties.
  • GMP experience, and direct experience following manufacturing instructions and all associated record keeping. Examples include IQ/OQ, and the ability to fully document and validate procedures, protocols, and SOP's.
  • Experience integrating (dying) fluorescent molecules into both magnetic and non-magnetic microspheres ranging in size from 2-25 microns.
  • Experience with the Coulter Principle of particle sizing/counting on the Multisizer line of instruments, i.e. Multisizer 1-4. SEM experience although not required is desirable.
