Pros
The engineers, technicians and project managers that I worked with locally were a highly intelligent, hard-working and creative group. Sadly, nearly every one quickly reached a level of intolerable frustration and left for greener pastures. I've talked with many of them; with well over 150 years of combined work experience, the consensus is they have never experienced a worse company. Not a single person I spoke with is sorry to have left.
Cons
This Indian-owned company with offices in the US (originally Optical Systems of India, now officially renamed "OSI") has intensely short-sighted management, directed by a myopic CEO who is famous within the company for his erratically uninformed temper tantrums. Management does not stay focused on anything very long, and this is reflected in the fact that quarterly performance is given far greater importance than annual - which leads to booking orders from one quarter to the next just to disguise natural fluctuations which would otherwise lead to boardroom tirades. Business is often fast and loose, which is how they got in trouble with the TSA on multiple occasions, and were even temporarily barred from screening system sales to the US government. It is often repeated that workers are a merely a commodity in India and that is very evident at Rapiscan and OSI. If you are not part of CEO Deepak Chopra's family, you are expendable. There is little loyalty to employees, and layoffs abound. From nearly the moment that our small company was acquired, there was a push to transition our knowledge (and I quote) "to lower-cost engineers in India" and "reduce workforce here in the US". Within 2 years, nearly everyone saw the writing on the wall and left or were laid off.
