Pros

The company culture is fantastic and they seriously take care of their employees! Loads of paid time off (even for new hires) and retention incentives like bonus $ and additional vacation days for those staying at least 5 years. Beautiful campus, friendly team atmosphere, and overall quality employer

Cons

Some individual departments are less than ideal to work in, mostly due to a few bad hires that stick around forever (causing otherwise good employees to leave). But that being said, almost every big company I've worked for has that issue at some point... so not really a red flag, just bad luck if you happen to fall into one of those groups at the wrong time.

Pros

Ionis is a great place to work and has a workplace environment that encourages innovation and professional development. Most decisions are made in a transparent way. The company and its employees are focused on work that benefits patients and their caregivers. I highly recommend this company to anyone who wants to make a difference for patients.

Cons

Company needs a greater sense of urgency to move promising investigational medicines through development and to patients as quickly as possible. There is a lot of focus on doing great science but not enough focus on getting medicines to patients asap.
