I can't find the Noc code for Aircraft Systems Engineer

[Abebanesh]

Hi all! I work for a commercial airline company and my department is called Aircraft Systems Engineer. I've looked through all the Aircraft related Noc list but the only thing I could find is a sub-category Noc called Systems Engineer, aerospace. Is that the same as Aircraft systems engineer? Or any of you guys have found a closer Noc code for this occupation. Thank you!
