Jobs for people with RepRap skills

If you are an employer and you need people who know RepRap, you can post job advertisements and links to job advertisements here. Please give potential employees links to a route (such as an online form on your company's website) to allow them to reply to you directly and in confidence, rather than getting them simply to post public replies here. Reprappers: the appearance of a job advertisement here does not mean that the RepRap Project endorses the employer. Do your research before replying to advertisements.
