<p>Out of the Linkabit offspring’s, two companies that I’m aware that are mostly hardware and defense related is Qualcomm and ViaSAT.
And the rest from your list, I highlighted in bold the ones that are defense/defense related and hardware/semiconductor, and some of them really advisory, such as MITRE which is a FFRDC, government related, Leidos, another adversary but not FFRDC. I know back in the East Coast MITRE hires a lot of engineers from MIT but it’s hardly a company that I consider working if I want to keep my skills set. The jobs are stable but as my husband sometimes put it, it can be intellectually insulting(no, don’t ask me to explain in public).</p>
