Job Description

CORNERJOB is the leading recruitment-app in France, Italy, Spain and Mexico for blue collars (80% of the labor market).

Since our launch, we helped close more than 100,000 employment contracts. We raised a total of $35 million in less than a year to support our growth, international expansion and product development strategy.

We are disrupting the way candidates and employers meet each other through a frictionless, simple and elegant mobile experience. The staffing industry is currently experiencing a revolution and we are reinventing the way employers search and find the right match. The labor market moves with greater fluidity than ever in most sectors: hotels, restaurants, retail, call centers, transportation, tourism, etc. Ourgoal is to become the one stop shop for candidates and employers by ensuring the fastest and easiest match.
