THE ORGANIZATION
The Alliance of Bioversity International (
www.bioversityinternational.org) and the International Center for Tropical Agriculture (CIAT) (
www.ciat.cgiar.org) delivers research-based solutions that harness agricultural biodiversity and sustainably transform food systems to improve people’s lives. Alliance solutions address the global crises of malnutrition, climate change, biodiversity loss, and environmental degradation.
With novel partnerships, the Alliance generates evidence and mainstreams innovations to transform food systems and landscapes so that they sustain the planet, drive prosperity, and nourish people in a climate crisis.
The Alliance is part of CGIAR, a global research partnership for a food-secure future.
Background:
The Alliance of Bioversity International and CIAT leads cutting-edge initiatives leveraging computer vision for plant phenotyping. The objective is to design, validate, and deploy robust computer vision phenotyping systems capable of operating seamlessly across mobile phones, uncrewed aerial vehicles (drones), and rovers within breeding centers across the CGIAR network. By harnessing artificial intelligence and advanced digital phenotyping, we aim to modernize conventional breeding approaches and accelerate the development of high-yielding, climate-adapted seed varieties of staple food crops.
About the positions:
The consultants will support end-to-end MLOps workflows spanning data ingestion, validation, dataset versioning, model training, evaluation, deployment, monitoring, and continuous improvement across both cloud and edge environments. The roles will involve close collaboration with research machine learning, software engineering, product, and field teams to ensure systems are robust, maintainable, and aligned with project needs.
The consultants will also support the integration of ML systems within the ONA platform, a dedicated web- and smartphone-based platform for computer vision phenotyping, including deployment workflows connecting mobile applications, cloud infrastructure, visual data pipelines, disease detection and severity scoring workflows, backend services, and FAIRGrounds-integrated systems. In addition, the roles will contribute to strengthening best practices around experiment tracking, model governance, CI/CD workflows, deployment automation, and ML system monitoring across ONA infrastructure.
These are 11-month full-time consultancy positions (with potential for extension) based at the Alliance office in Arusha, Tanzania or Nairobi, Kenya.
