These are the ATS keywords, credentials, and software terms that recur across current embedded systems engineer job descriptions — organized so you can scan for what your resume is missing. Placement matters as much as presence: an ATS keyword buried in a skills list ranks lower than the same term used in context inside an experience bullet.
