Pros

I really do not have much to say here. The Irvine area is nice and there is a nice koi pond in the new building.

Cons

The only thing I learned in my year and a half at Masimo is how not to treat people. I worked in the quality compliance group from 2015-2016 and I can still remember all the bullying and name calling that I was subjected to. Truth be told, I was super excited about joining Masimo in 2015, even though majority of the reviews on Glassdoor were negative. Boy was I wrong. Three months into my journey, my direct Manager left the company and let me deal with the obnoxious management in the Quality Compliance (QC) Group. Example: I am always in my office at 7 am and Management comes in at 730 and sets up a meeting to resolve an issue. However, I needed time off to take my son to the hospital and so I proposed a meeting at 7 am as soon as I got in. Without seeing my request, an invitation was sent to me to discuss a department issue. I informed management of my circumstance and I kid you not, he flipped and started cussing at me. Even though all this was going on, I still ploughed my way through because I had a family to support. However, they will find a way to fire you. The last straw was when Management was holding meetings behind my back with lawyers and HR to discuss my performance. They set up metrics in November 2015 to monitor each department’s performance. The metrics were evaluated from November 2015 to June of 2016. I was green on all of my metrics except for the month of November but apparently, I wasn’t doing a good job. However, the spineless HR department decided to put me on probation. In my 20 years, I had never experienced anything like this. Come to find out, the QC Management did not like me and wanted me out. This is not a complete list of all the abuse that I had to deal with. Trust me, nothing is worth this aggravation. Can’t speak of other departments, but I think the culture is same throughout the company. Do yourself a favor; AVOID MASIMO AT ALL COST.

Pros

Danaher came in and this new ceo will be better than the last one. Innovative devices that make a real difference in clinical environments. Talented, dedicated engineers and individual contributors who are passionate about quality and results. Competitive benefits and resources supporting the technical work.

Cons

senior leadership appear disconnected from actual operations. They often seem to know little about the day-to-day realities and contribute minimal practical value, leading to poor decisions, bottlenecks, and wasted effort for the teams doing the real work. Increasing bureaucracy and top-heavy structure that slows down progress despite the strong capabilities of the people on the ground. A noticeable gap between executive influence and actual impact, which is frustrating even as a newcomer observing it. Key talent and legacy know-how are leaving at a concerning rate, which makes newcomers like me nervous about the company’s long-term knowledge retention and stability. Gossip is rampant, further eroding trust and team cohesion.
