Contracting Consultants
Recurity Labs works, additionally to our internal team, with a body of contracting consultants. This group consists of hand-picked personal with exceptional skills in specific areas. Close cooperation with contracting consultants is one of the core operating concepts in Recurity Labs. Specialists often don't fit into permanent employment, since it steals the self-development time they need and want. On the other hand, permanent positions cannot constantly provide challenging missions. Recurity Labs tries to balance the two, achieving a high acceptance by the contracting consultants and full satisfaction of the customer, who gets extra specialist knowledge with the quality of Recurity Labs work.
