Pros

Working from home. This helps reduce daily exposure to a toxic internal culture.

Cons

There are significant and ongoing issues around diversity and inclusion at senior levels. Leadership and board composition lack meaningful representation, with very limited diversity and a noticeable absence of women in decision-making roles. • Despite strong external messaging around values and inclusion, the internal reality does not reflect this. DEI initiatives feel performative rather than embedded in accountability or leadership behaviour. • Culture is hierarchical and political, with progression often driven by informal networks rather than transparent, merit-based processes. • Speaking up is not psychologically safe. Challenging the status quo is discouraged, and concerns are frequently minimised rather than addressed. • High levels of disengagement and turnover are treated as normal rather than as warning signs.

Pros

Great people -a lot of smart type A personalities so you have to have the ability to let things roll off your back. I found the people to be very dedicated and willing to work well as a team. Great benefits. They have upgraded their ERP systems and are investing into the most recent technologies (e.g. AI and other function specific related technology). They have a great mission in helping patients by helping to accelerate life saving therapies worldwide.

Cons

They don’t have the most transparency when comes to job titles, job grades and the related salary minimum and maximum-but they are working on it (at least this was the case when I voluntarily left for retirement in 2025-so that is good). It’s a fast paced environment that at times can be quite demanding.
