Data Scientist

Who We Are: Girl Effect builds media and tech that adolescent girls in Africa and Asia want, trust, and need. Reaching over 50 million girls, the organization provides safe spaces to access crucial facts about health, education, and relationships, empowering them to redefine what is possible. We operate three chatbots in India, South Africa and Kenya which have reached nearly 3 million users, providing answers at scale to the most pressing questions related to sex health, mental wellbeing and livelihoods, whilst directing users to real world services. In the next 5 years, we intend to scale even further. By 2030, we believe we can reach 30 million girls through our chatbot solutions, providing highly personalised experiences augmented by Artificial Intelligence. The Tech & Evolution The Shift to GenAI: For over a decade, Girl Effect has leveraged user insights to build safer digital platforms. The integration of Large Language Models (LLMs) has fundamentally transformed their product offerings. Current Scale: Our custom GenAI feature—which safely sits behind strict, custom guardrails—has already processed over 150,000 user submissions. Plans are underway to expand this feature to mixed-coded languages in South Africa, Kenya, and India. The Next Frontier: Girl Effect is moving from simple question-answering to creating complex, long-term conversational pathways such as Single Session Interventions (SSIs) for mental wellbeing. Our interactions are deeply rooted in behavioral science, designed to safely nudge vulnerable young users toward positive health outcomes.
