RobertFL,
In the USA your age will not be a factor, however in Europe with the current job climate I cannot say. I had an ex-flight instructor colleague of mine (British citizen, FAA ATP) did the PPSC licence conversion and secured his CAA ATPL.
He was in his mid thirties, the problem he had was getting an interview for his first job. He had sent numerous CV's over a period of more than nine months and this was back in 1998 when the job market was a lot better.
The issue he found was that his U.S. experience was given scant regard by some companies and was even told that by a chief pilot for one of the companies he interviewed for! Fortunately he got a start with Emerald and has now moved on to Air Contractors so there is hope.
You may find this supercilious conciet, that is prevalent in the old world more of a hurdle than your age. You don't state your experience level or nationality in your post so your circumstances may be different.
Best of luck to you.
