Challenging, rewarding work

Optical engineer

Recommend

CEO approval

Business Outlook

Pros

Innovation is encouraged and rewarded Optical supplies procurement is greatly eased by being a part of MKS family, which includes Newport Friendly, hands-off managers

Cons

IT department is understaffed, which made onboarding a pain. Management inexplicably laid off our machinist, which meant that rapid prototyping had to go through external machine shops.

A good gig, but poor leadership

Inside sales engineer

Recommend

CEO approval

Business Outlook

Pros

Great salary Work From home Stock Purchase Plans

Cons

Process changes and leadership selection have caused chaos at present. Process change almost daily. Lack of effective training on the company CRM, SAP, and paths for escalation make mistakes easy to make. The biggest con thought is the lack of feedback you will get on how you personally are doing WILL cause you to feel uncertain about your effectiveness. The managers almost never give positive feedback.
