MKS Inst. Review

Pros

Management/C-suite consistently engages with employees. There is a strong focus on the future and the company provides employees learning opportunities. The starting wages are relatively competitive for my area. The projects I am working on have been rewarding and enjoyable.

Cons

Employee perks/benefits/pay shrink year-over-year. This is due to salary increases being outpaced by inflation, increases in insurance being passed on, and pto benefits being capped and not paid out. When management is given a tough question, it seems to be side-stepped with a "pc" answer.

Thank you for highlighting both the impact of our products and the respectful environment you've experienced. Our teams take great pride in developing technologies that power possibilities across industries, and it's good to hear that sense of purpose comes through in the day-to-day. We also hear your point on culture and community. With a global company like ours, it can sometimes take more intention to find that connection — but we strongly encourage employees to take part in our employee resource groups (ERGs), which are open to everyone and offer great opportunities to build community, collaborate, and share ideas across the company. Everyone is welcome to take initiative and get involved — or even help shape something new. If you'd like to share additional ideas or feedback, you can write to us directly via mks.feedback@mksinst.com or through our internal Digital Dialogue platform.
