Pros
"The Mission" to create drugs that are helping society and keeping people alive is amazing to be a contributor on. It is nice to work with and learn about interesting things that the scientists are working on. Compensation and bonuses are great. Genenbus system makes it easy to get to work from anywhere in the area when COVID is over. Lots of opportunity to move laterally to join different teams and work on novel things, so boredom is rarely an issue.
Cons
Large amount of bureaucracy throughout the organization causes decisions that should take hours to take weeks or months. Most of the actual software engineering and development work is outsourced to contractors in countries around the world where labor is cheaper so if you want to actually write and develop software, this may not be the place for you. Internal politics and lack of communication between groups within the research organization are not great. The scientists and researchers that you collaborating with can be very headstrong and diva-like.
