About Us

Box Africa is a rapidly growing IT services company operating across West Africa. We are launching a dedicated AI division to deliver high-impact, applied AI solutions in fintech, telecom, banking, health, agriculture, and the public sector.

Our ambition is to build the leading AI practice in West Africa, combining cutting-edge research, applied machine learning, and local talent development.

Main Responsibilities

As a Senior Data Scientist, you will play a key role in advancing Box Africa’s AI practice. You will design, prototype, and deploy state-of-the-art AI models with a focus on Natural Language Processing (NLP), Retrieval-Augmented Generation (RAG), and Applied AI use cases relevant to Africa.

1. Research & Development

• Lead the research and prototyping of models in NLP, LLM fine-tuning, multilingual and multimodal AI.
• Develop and optimize RAG pipelines for African languages and domain-specific contexts (banking, telco, fintech, health).
• Drive applied research in Intelligent Document Processing (IDP), automating information extraction and classification.
• Explore AI for risk scoring, credit scoring, and credit exposure loss prediction (IFRS9 ECL models).
• Investigate and apply agentic architectures and agents-as-a-service to real-world enterprise problems.
• Stay ahead of emerging trends (explainable AI, bias mitigation, reinforcement learning, multimodal AI).

2. Model Development & Production

• Design and build end-to-end AI models, from proof-of-concept (POC) to production deployment.
• Collaborate with AI engineers to ensure robust MLOps integration (training, versioning, deployment, monitoring).
• Apply XAI techniques to ensure explainability, fairness, and regulatory compliance.
• Deliver scalable, production-ready solutions addressing financial services (fraud detection, risk scoring), telecom, and public services.

3. Collaboration & Mentorship

• Work closely with the Head of AI & Strategy and the AI Engineering Manager to shape Box Africa’s AI practice.
• Mentor junior data scientists and foster a culture of applied research and innovation.
• Collaborate with client teams to translate business challenges into AI-driven solutions.

4. Impact & Ecosystem Building

• Contribute to the design of AI services tailored to West Africa (IDP for banks, credit scoring models, multilingual assistants).
• Publish findings, represent Box Africa at conferences, and grow our presence in the African AI ecosystem.
• Position Box Africa as a pioneer in applied AI & agentic systems across UEMOA and West Africa.
