Vantaggi
In general the teams here are very good and there is a lot of ambition to change how things are done to move faster and more efficiently. The execution of that is better said then done, but the want is there. The benefits are about what you could expect for big Pharma (average vacation, 9% 401k match (150% of 6%), okay healthcare, good parental leave for the US, average bonus structure for the industry (dependent on level and personal & company performance).
Svantaggi
Pay. The pay here is very, very low compared to the industry. I cannot stress enough how low it is and how much HR will try and gaslight you into believing it is competitive. The pay ranges are absurdly wide. Every team is underfunded (don't blame your boss, they have no options). If you are coming from another company negotiate as much as possible because once you are employed the only real raises (even if you are a high performer) you will get are for promotions. Yearly raises are non-existent. What budgets managers get from HR for yearly raises get spent on keeping exceptionally low paid team members from falling off the pay scale.
