For now, just a quick rundown of the number of available chemistry-related (broadly defined) positions in 10 major pharmaceutical companies. I searched on the individual company's website; the search term used was "chemist" and only positions in the US were counted.
Pfizer: 6
Roche: 1
Merck: 10
Novartis: 4
Johnson & Johnson: 18
GSK: 3
Sanofi: 5
AZ: 1
Lilly: 4
BMS: 12
Takeda: 5
At some point, this will solidify into a routine list, but I just thought I would get it started.
