Nedbank Group is a financial services group in South Africa offering wholesale and retail banking services as well as insurance, asset management, and wealth management. Nedbank Limited is a wholly owned subsidiary of Nedbank Group.
Job Overview
- To lead and grow a high-performing team focused on advanced Machine Learning (ML) modelling and artificial intelligence capabilities that drive strategic value across the organization.
- This role is accountable for the development and operationalization of cutting-edge AI solutions, including predictive modelling, and generative AI.
- It enables scalable, reusable, and ethical AI practices by fostering cross-functional collaboration, embedding robust governance, and aligning with enterprise-wide data and digital strategies.
Responsibilities
- Define, grow, and lead a team of Data Scientists and ML Modelling Experts across proficiency levels, fostering technical excellence, delivery discipline, and innovation.
- Develop and deploy traditional ML models across key financial services domains fraud detection, collections, AML, operations, etc; using techniques like regression, classification, clustering, and time-series analysis to support decision-making and regulatory compliance.
- Advance customer and business intelligence through behavioural modelling, segmentation, lifetime value prediction, churn modelling, and recommendation systems — leveraging ensemble methods, graph-based learning, and temporal feature engineering to drive personalization and strategic growth.
- Explore and integrate advanced modelling approaches, including deep learning, graph neural networks, and retrieval-augmented generation (RAG) models — to enhance model performance, enable contextual understanding from unstructured data, and support emerging use cases such as document intelligence and GenAI-assisted analytics.
- Apply specialised ML techniques such as computer vision, natural language processing (NLP), and large language models (LLMs) to solve domain-specific challenges — including document classification, KYC automation, sentiment analysis, and intelligent customer interaction across banking channels.
- Identify opportunities across the Nedbank Group to enhance model performance and scalability through foundational capabilities such as feature engineering, graph-based data representation, and reusable modelling assets.
- Apply financial services domain knowledge to ensure models are aligned with regulatory requirements, business priorities, and industry-specific data characteristics.
- Collaborate closely with internal stakeholders — including business, data science, engineering, and platform teams — to ensure modelling solutions are integrated, governed, and strategically aligned.
- Introduce and support GenAI capabilities, particularly retrieval-augmented generation (RAG) models, where they complement traditional modelling — e.g., enhancing model explainability, document summarization, or contextual data retrieval.
- Design and manage data pipelines that support both traditional ML and GenAI workflows, including real-time and batch feature computation from structured and unstructured data sources.
- Drive innovation in feature creation, leveraging advanced techniques such as graph-based feature extraction, temporal feature engineering, and embedding generation.
- Lead the implementation and operation of scalable, reliable, and governed modelling platforms, ensuring they are production-ready, secure, and aligned with business needs.
- Own the lifecycle of modelling assets — including availability, documentation, versioning, monitoring, and governance — to ensure high-quality, trusted inputs for ML and AI solutions.
- Solve complex, unstructured problems with a detail-oriented mindset, working independently and driving initiatives to completion.
- Possess strong business and communication skills, enabling effective collaboration with business owners to define key modelling needs and ensure foundational assets meet those needs.
- Manage financial and business results, ensuring delivery within budget and timelines, and compliance with divisional billing and cost recovery processes.
- Deliver high-quality modelling systems and processes aligned to Nedbank’s strategic goals, data strategy, and AI roadmap.
- Provide timely, professional advice and strategic input to stakeholders, ensuring delivery within agreed quality, budget, and time parameters.
- Build and maintain strong stakeholder relationships by delivering consistent, high-value modelling services and solutions.
- Actively engage with clients, partners, and internal teams to build trust, align expectations, and ensure delivery of best-practice modelling foundations.
- Promote knowledge sharing and collaboration across teams and departments to strengthen the modelling and AI capability.
- Operationalize divisional strategy by aligning team priorities and empowering first-line managers with clear roles, performance measures, and delivery goals.
- Leverage professional frameworks, tools, and technologies to deliver scalable, strategic modelling solutions.
- Manage multiple foundational modelling assets through strategic planning, implementation, and continuous improvements
