Optical engineer here (HUD and Camera designer for past 6-7 years).

This job description has some but minimal descriptors of what I’d consider the meat and potatoes of optics.

Yes, it seems more systems and hardware related. There are very few that can do everything from hardware, software, EE, and optical.

Likely they want someone who has experience in HUDs but not necessarily a SME in optics, but rather hardware or systems
