STOP THE TRAFFIK prevents vulnerable communities from being recruited, trafficked, and exploited. Our targeted prevention efforts disrupt the criminal business of human trafficking, making it too high-risk and low-profit to sustain.

We're looking for an Impact Manager to lead the way STT measures, evidences, and communicates the difference our work makes, coordinating our impact measurement framework, managing KPI data and dashboards, supporting grant and programme design, and turning evidence into clear reporting for funders, the Board, and SLT.
