Tanzania Market Access Lead (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 Tanzania program, founded in 2013, supports more than 100,000 farmers with quality farm supplies, as well as fruit trees. Our team in Tanzania is headquartered in Iringa and supported by three smaller offices Mbeya and Njombe in the southern highlands, and Moshi in the north where the team is focused on expanding our services to new clients. One Acre Fund works in select areas in the Iringa and Mbeya regions, with a growing presence in the country’s north. About the Role Are you a strategic commercial leader with a passion for building market systems that work for smallholder farmers? This is a senior role at the heart of OAF Tanzania's commercial ambition. Reporting directly to the Country Director, you will define and lead the organization's market access strategy and portfolio—deciding which value chains to prioritize, shaping the commercial model for each, and building the partnerships needed to make them viable. Initial priority value chains include cashew and avocado. In practice, this role is roughly two-thirds commercial and analytical design, and one-third strategic leadership. You will own business cases, margin analysis, and commercial negotiations directly, while driving farmer-facing field delivery indirectly through a established layer of specialists, coordinators, and supervisors. If you are ready to build commercially viable value chains that transform smallholder farmer incomes at scale, we would love to hear from you. Responsibilities Market Access Portfolio Strategy & Prioritization Strategic Roadmap: Define the multi-year strategy across priority value chains (e.g., cashew and avocado) with clear sequencing and resourcing. Opportunity Assessment: Evaluate and recommend whether to invest, partner, pilot, or scale specific value chains based on commercial viability and farmer impact. Portfolio Allocation: Provide strong, data-driven recommendations to country leadership on how to allocate the department's time, people, and capital. Value Chain Development Commercial Model Design: Develop commercially sound models for aggregation, processing, value addition, and export, determining the best delivery approach (direct vs. partner-led) for each context. Deal Structuring & Negotiation: Lead the identification, diligence, negotiation, and contract structuring with strategic commercial partners, processors, and offtakers—owning pricing logic, margin targets, and service level expectations Field Delivery Oversight: Set performance targets (produce quality, aggregation volume, offtake execution) and hold the specialist, coordinator, and supervisor layer accountable for field results without running daily field operations personally Performance, Analysis & Risk Management Business Case Ownership: Build and defend unit economics, margin models, business cases, and growth plans across active value chains. Data-Backed Governance: Establish tracking systems for adoption, supply, sales, and partner performance, using live data and financial analysis from pilots to make firm recommendations to scale, redesign, pause, or exit workstreams. Risk Mitigation: Identify operational, commercial, and regulatory risks early to implement sensible mitigation strategies.
