Pros

Work life balance and free coffee.

Cons

I left this job with more frustration than growth. The level of incompetence and bias in the management team is staggering. Micromanagement, feedback met with outright hostility, inability to reflect and improve - this site checks all the boxes.

Pros

I’ve been with this company for over a decade, but lately it feels more like a trap than a career. The culture has deteriorated rapidly, especially after the abrupt and demoralizing return to site mandate that felt more like a punishment than a policy. The environment is tense, disjointed, and disheartening. The only thing keeping me here is the health insurance otherwise, I would have moved on already. If you’re thinking about applying to Lonza, I’d recommend holding off, at least until the organization re-evaluates how it treats its people.

Cons

Management is siloed and often plays favorites, creating a toxic atmosphere where retaliation isn't uncommon. Decisions are reactive, not strategic, and forethought is practically discouraged. The pay is decent, but it comes with a heavy emotional toll. After a while, you’ll start dreaming about work and wondering if your growing collection of bourbon bottles counts as a hobby or a warning sign.
