Age matters far less than skill set. I've ran into very little ageism. The caveat being I am not at the top 1% of companies. The problem with older engineers (myself included) is that their skillsets tend to atrophy. When you're a young gun you're jumping languages and frameworks as soon as they come out. When you're older, generally, you settle into a nice spot and stay there. I'd estimate you'd do as good as someone 20 years younger than you provided you are willing and able to learn the newest hotness in your chosen sub-field. This all being said I have personally seen 0 candidate over the age of 30 in the last 3-4 years of interviewing. Some of this might be how my job selects candidates, but given they selected me, and my boss is similarly aged, I would guess that there's a lot of aging out that happens naturally due to the factors I mentioned.
