Rwanda Plant Nutrient & Soil Systems Research Senior Specialist / Associate (Fixed-Term)

About One Acre Fund

Founded in 2006, One Acre Fund equips 5.5 million smallholder farmers to make their farms more productive. Across nine countries that together are home to two-thirds of Africa's farmers, we provide high-quality farm supplies, tree seedlings, accessible credit, modern agronomic training, and a wide range of other agricultural services. On average, this model enables any farmer to increase their income and assets on supported land by more than 35 percent, while permanently improving their resilience. This is all made possible by our team of 9,000+ full-time staff, drawn from diverse backgrounds and professions. To learn more, please see our Why Work Here blog post.

Our Rwanda program, founded in 2007 is our largest and operates under the local brand Tubura. We have more than 3,000 staff across all four provinces of Rwanda, as well as in Kigali. Together, we served more than 2.8 million farmers in 2024. We work closely with the government to support national efforts to improve food security. Additionally, we help channel funding and resources to promising agri-SMEs, supporting farmers by providing a market for high-impact crops such as coffee, avocado, and chili.
