Baton Rouge, LA: Albemarle is looking for an entry-level Ph.D. NMR spectroscopist. Not every day that you see that.
Rolla, MO: Brewer Science, searching for a B.S.-level senior research associate.
San Francisco Bay area: I think this Bolt Threads engineering job sounds pretty interesting. Why it is at C&EN Jobs is beyond me, though.
More engineering positions: Myriant is located in Lake Providence, Louisiana. Looks like they're hiring chemical engineers and paying decently (?).
