I couldn’t find anything about the operator. No website, no phone number, no address.
It’s definitely legit if you have the required hours though.
This could be one of the few undergound mom and pop aviation businesses out there, that you could probably snag a job with, if you were local.
I don’t know how their business grow without any sort of digital presence (and speaking from experience, I wouldn’t recommend flying for businesses like that unless you know for sure how much you’ll be flying: never good to fly for a dying industry/operation)
For all we know, this might just be a collect email/account, where the employer has application sent to, dedicated just for that, hence the name and the absence of any other information to identify them.
You’ll have to actually subscribe to climbto350 to apply for this one.
So unless you have the requirements, don’t waste your money.
I also just wanted to make a point that old school employers still use job boards like climbto350.
Best of luck!
