Description

Within ICIB we believe in deeply embedding our engineers into the different businesses that we run. As an AI engineer, you will sit close to the business teams you support, building an understanding of the workflows, risks and opportunities where applied AI can deliver measurable value. Our technical skillset includes AI engineering, software delivery, data science, business analytics, automation, workflow design, compliance and risk-aware solution development. We use enterprise data assets, business knowledge, document repositories, APIs, workflow tools and market information to build practical AI applications that improve decision-making, productivity, control and client outcomes. The expectation of the role is to design, prototype, evaluate and support the development and deployment of AI applications, including LLM-powered agents, RAG assistants, workflow automations and controlled pilots that can progress toward production use. Our model is that of project ownership, asking our consultants to build end-to-end partnerships and solutions as per business requirements. From engaging stakeholders on the business need, to developing and evaluating technical solutions, to presenting findings through clear storytelling; you will own and drive projects. The candidate's technical responsibility will focus on building, testing, reviewing and delivering safe, reusable AI solutions, quantifying business value and driving our AI capability forward. A risk-conscious approach to toolset, model, prompt, data source and workflow selection is critical, with a firm view to ensure auditability, security, fairness and appropriate human oversight. Adherence to important regulatory standards like POPIA is a must. Your role will be project based with day-to-day development of solutions, engagements with key stakeholders, prioritization of AI opportunities and the ability to create a platform for generating, testing and scaling new ideas.
