Pros

The Cambridge / Boston team is genuinely kind, smart, and interesting. There's occasionally interesting science, and international travel opportunities exist, though there has been a companywide ban since the 2023 Solvay/Syensqo split that is only recently thawing. The 401k matching is attractive, though requires 4 years to vest. The site has free coffee and sparkling water.

Cons

My review reflects my experience thus far at the Cambridge MA (internally called Boston) site: I've worked in academic labs, early stage startups, and larger multisite companies. None of it prepared me for the degree of burnout this role has produced for multiple capable, credentialed scientists who arrived motivated, gave honest feedback through the channels provided, and kept giving the benefit of the doubt. A company-wide "Pulse Survey" showed 20% of Cambridge feeling calm at work versus 52% company-wide avg, and 40% feeling motivated versus 59% avg. I'll list the reasons I believe it's gotten this bad below: 1) The interview greatly overpromised. I was told I'd be taking on a significantly broader scope (management responsibilities, technical contributions across my areas of expertise). Very little of what was described materialized. Be specific about what the role actually is right now, not at an imagined future headcount that may never materialize, and get anything important to your decision in writing. 2) One of the core problems is a failure to connect scientific capability to business direction. Without it, capable scientists end up doing work misaligned with their training, or interesting projects get abruptly cut short once someone upstream realizes they were never tied to a market need. The cumulative effect on motivation is significant. 3) Site leaders bred a culture of mistrust. The posture toward employee needs has consistently been "what are we legally required to provide"--and sometimes not even that. A paid sick leave compliance issue under Massachusetts law required a site scientist to spearhead over a year of internal requests that went nowhere, including being advised to record time in ways that did not reflect reality. Requests from multiple team members for modest flexibility explicitly within the stated "mobile working policy" (as little as one day of remote work per month or working 4 nine hour days and a half day Friday) were declined. If you think you might want *any* flexibility for occasional work at home, get the site-level interpretation of the policy in writing before you accept. 4) Scientists have been asked to operate equipment with little or no training, even when it was explicitly requested for safety. 5) Salaries are not adjusted for location; Cambridge and Philadelphia are treated as equivalent despite Cambridge having a roughly 25% higher cost of living. Raises have not tracked inflation. 6) The site is small without meaningful oversight. If your relationship with your manager isn't working, there is no realistic path for mediation or improvement. Overall, if you're early career with low expectations for role definition and don't mind being on site at least 9-5 daily (with additional weekend work expected), you might be okay. But if you're a strong mid-career scientist with options, proceed carefully.

Pros

The only good thing is the benefits (health coverage, etc), though the salary is lacking if you're not an operator.

Cons

So many people have quit in the last 2 years, it is such a toxic workplace. If you're an operator you will have a good job but everyone else suffers. There is no serious attempt to improve the culture of the workplace, even though everyone knows it's been struggling for years. As a new employee the training is lacking, you have to figure out everything on your own.
