The newly approved positions have been on the "back burner" for some time. They (the managers) have had a stack of resumes sitting on their desks for nearly a year. Because of this, some positions have already been filled. I'm not sure if there were any positions approved for the backshop. Your best bet is to be patient. What is your experience level? We currently have a lot of experience in the engine shop, and I'm sure that they aren't leaving anytime in the near future. Do you know anyone who is currently working here? After holiday (Eid), I'll ask if there are any available engine backshop positions still open. No promises. Best of luck.
Unfortunately, there are no open engine (flightline or backshop) positions at this time. I would suggest checking back on the careers website for any future positions. Give it some time. One may open up for you. Good luck and best wishes.
