Hi,
the Progress job market in Ireland is very small, there are approx 15 - 30 progress companies in Ireland I think, ranging in sizes. But positions are advertised every now and again.
I might get in touch with Iain Patrick, the Progress representitive for Ireland if I was in your position. He has spent a lot of time trying to build the progress community in Ireland and would possibly be able to provide you with a list of company names using Progress that you could drop a cv to? But I don't know if he would give out that information or if he is allowed to? If you are interested, I could dig his email address out.
I know that Precision software are based in Dublin, they are large enough with sites in Europe and the states. Also LabSys is another.
The main jobs websites in Ireland are monster.ie, jobs.ie but as I said the community here is small so Progress jobs might not appear very frequently.
Your post is from ages ago, so you might be elsewhere or already have a job by now. Either way, best of luck!
Fiona.
