JOB DETAILS:
Background
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.
The NDIZI (NLP to Develop and Innovate Zero-shot Intelligence) project seeks a dedicated Machine Learning Operations (MLOps) Consultant (“the consultant”) to support the development, deployment, and operationalization of machine learning systems powering SIKIA, a voice-first and multimodal AI platform for conversational data collection and analysis, and related AI-driven research workflows. The consultant will work across speech, NLP, multimodal AI, and Agentic pipelines, helping transition models and data systems from research prototypes into reliable, scalable solutions suitable for real-world field deployment.
We are building these systems to enable crop improvement systems to bridge formal breeding processes happening within controlled experimental trials with real-world environments on-farm. Principal use-cases include identifying farmer preferences, assessing plant disease occurrence and scoring, and environmental response – particularly related to climate adaptation. Outputs from this consultancy will be used to address these use-cases.
About the position:
The consultant 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 role 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 consultant will also support integration of ML systems within the SIKIA platform, including deployment workflows connecting mobile applications, cloud infrastructure, speech and multimodal pipelines, disease detection and severity scoring workflows, backend services, and FAIRGrounds-integrated systems. In addition, the role will contribute to strengthening best practices around experiment tracking, model governance, CI/CD workflows, deployment automation, and ML system monitoring across NDIZI infrastructure.
This is a 11-month full-time consultancy position (with potential for extension) based at the Alliance office in Arusha, Tanzania.
