Cool! I&#x27;m no expert, but optics, aerospace, and defense mainly that I&#x27;m aware of. Airbus has a huge wing manufacturing plant in Broughton which I&#x27;m sure helps anchor the industry, they have massive tie-ins with the local universities through apprenticeships. Prototype mirror segments for the E-ELT project are also being built here[1] (last I checked; there&#x27;s been some budget problems). I don&#x27;t know everything that goes on of course, but my own job searches have turned up both interesting-looking embedded work and more run-of-the-mill web stuff, despite my earlier comment. I&#x27;ve seen lots of datacentre&#x2F;hosting type companies kicking about as well.<p>It&#x27;s no Silicon Valley - Wrexham, the population centre, isn&#x27;t quite (though very nearly) big enough to hold the interest of the intellectually curious - but it&#x27;s a lot more vibrant than you hear about. Here is the business directory of the business park in St Asaph where they&#x27;re building the mirror segments:[2]<p>[1] <a href="http:&#x2F;&#x2F;www.glyndwrinnovations.co.uk&#x2F;articles&#x2F;latest_news&#x2F;the_uk_consortium_and_large_optics" rel="nofollow">http:&#x2F;&#x2F;www.glyndwrinnovations.co.uk&#x2F;articles&#x2F;latest_news&#x2F;the...</a>
