First thing ignore 40Hz as he seems to think the only engineering jobs are mechanic ones.
Next thing, keep an eye on
www.aviationjobsearch.com - you may not have the experience people are looking for yet but it'll give you company names. Astrium in Stevenage seem to be regularly on the lookout for graduate systems types and there are agencies advertising posts as well (these may be temp posts but they're a foot in the door). Airlines do recruit graduates but normally not straight from college, they like to see experience either in an OEM or hands-on. Keep reviewing their websites though as vacancies do come up. Do some homework to see which OEMs have engineering design facilities in the UK. RR, BAe, Honeywell, Astrium, Goodrich for a start. The full list of Part 21 companies (design/production organisations licensed by EASA) is here:
http://www.easa.europa.eu/ws_prod/c/...o/easa_doa.pdf - do some homework on the companies, what they do, which markets they serve. Don't expect a CV on the email to sell you any more than passing round a business card in a club would get you a date. Sell yourself, meaning understand what the company does, what it wants and how you can fill that need.
Approach the agencies serving the industry and get on their books. Be prepared to travel. Build a list of potential employers and keep a regular eye on their websites for vacancies.
Good luck!
