## About the role

Join our analytical lab in San Francisco as an Analytical Lab Chemist. You’ll run sample prep and analytical testing on state-of-the-art equipment in a newly renovated lab, keep data accurate and instruments performing at their best, and dig into problems that don’t come with a textbook answer, like an unknown sample straight from the plant. Found on 1752vc Careers, the job board for startup and VC roles.

- Hands-on ion chromatography (IC) experience strongly preferred
- Solid wet chemistry skills, including acid digestion and preparing standards
- Experience with ICP-OES/MS, XRF, AA, GC, HPLC, or UV-Vis, whether in research or coursework
- A troubleshooter who likes figuring out why an instrument or result isn’t right
