No you cannot work remotely at clean harbours. the job I had, I had to show up everyday at the office. I am not sure what type of work they have that allows for remote work but from what I experienced, you could not work remotely and had to physically be present at the job.
How can I apply for clean harbors
I am now live in Unaited Arab Emirates , DUBAI
As far as I know clean harbours do not have offices or branches out in Middle East. they're an American company and so most of their branches are in the states or in Canada.
