Contracting Consultants

In addition to its own team, Recurity Labs works with a body of contracting consultants. This group consists of hand-picked professionals with exceptional skills in specific areas. Close cooperation with contracting consultants is one of the core operating concepts at Recurity Labs. Specialists often do not 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 strives 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.
