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.

Pros

Healthcare and 401K are nice. Corporate office is beautiful and growing. Nice corporate outings and corporate events.

Cons

Women are being run out of this place rampantly. Senior Leaders and white males in cahoots with one another drive strong women out the door through bullying, secret smear campaigns and through harassing behaviors. Several women have already left either ones who found other opportunities and left negative feedback to HR on their exit, others bullied out while some still sit quietly awaiting another job opportunity will come quickly. All of which, the men continue to increase in power and the women become more vulnerable. Some women join in with these bullies to drive their careers or in fear of being treated the same. HR and Legal have done nothing to help and often side with the bullies. White men continue to get promoted and it's clear that negative behavior and rudeness get you further than being kind and doing your job. Burnout is at an all-time high, travel is rampant often 2x a month to Carlsbad or off site meetings. Work life balance is non existent. Its really gone down hill and if you are okay with being put in a box, managed by fear and forfeit your family for company- this is your place.
