Pros

Fast paced, you can learn a lot but it comes at a very high price

Cons

Internal politics, unprofessional work environment, the worst company culture I've experienced in my 20 year medical device career. The organization is poisonous, the people that are still there want to leave but don't have a lot of other opportunities - basically they're stuck. If you are considering working for this company, make sure you speak to employees that left, they will be happy to share their experience. Pay attention to key functions like engineering, regulatory and marketing, the attrition rate is extremely high and they don't have any plans to make it better. HR department is very weak- its an engineering-run organization with 3 people taking orders from the CEO and the rest of the organization is told what to do. Also, recruiters refuse to work with Masimo, they know how bad it is to work there and the bad rep is known all over the Southern CA area. Do your research!

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.
