Sigma Recruitment Ltd

Sigma Recruitment Ltd is an independent recruitment agency based in Cardiff that places permanent technical, engineering and manufacturing staff. Rhys Williams founded the business in 2005, after working in several recruitment agencies in Cardiff and, before that, at Robert Bosch. He is its managing director.

It recruits for employers in South Wales, across the UK and internationally. Its sectors include automotive, aerospace, electronics, chemical, food, packaging, pharmaceutical, life science, medical device, steel, plastics and semiconductor manufacturers. The roles it fills cover engineering, supply chain, procurement, logistics, management, scientific and graduate STEM positions.

Services range from contingency recruitment to retained executive search and headhunting. For each vacancy it agrees the brief with the hiring manager, advertises the role, searches its own candidate database and LinkedIn, screens candidates, arranges interviews and manages the offer. It recruits for permanent roles only and does not supply temporary or agency staff. It says four in five clients come back with their next vacancy.
