Senior AI Engineer

The Executive Directorate (EXD) stewards OECD resources on behalf of the Secretary-General with responsibility for people and wellbeing budget management security infrastructure and the OECDs convening activities. EXD provides corporate services and strategic advice on management and corporate policies to the Secretary-General Council and Standing Committees and delivers compliance and risk management functions within its remit operating in a fast-paced environment focused on management excellence. 

Within the Executive Directorate (EXD) the Digital Knowledge and Information Service (DKI) is responsible for overseeing corporate IT infrastructure and operations maintaining digital security information management and delivering digital and other IT-related products and services. EXD/DKI also supports the safe adoption of artificial intelligence (AI) technologies across the Organisation. 

Following the recommendation of the OECD AI Task Force and in line with the evolving AI-related requirements of the OECD the CAI division has been established to support the safe adoption of AI technologies across the Organisation. CAI is tasked with overseeing the shift from initial experimentation towards the scaled adoption of AI (from Exploration to Institutionalisation) that delivers tangible value with a clear emphasis on enhancing organisational impact improving productivity and transforming ways of working.  

In this role you will sit within the AI Lab in EXD/DKI/CAIO. The AI Lab supports the development and operationalisation of the OECDs corporate AI framework by identifying designing and implementing high-value AI solutions that strengthen the Organisations analytical and operational capabilities.  

You will be focused on building structuring and industrialising AI solutions to support the Organisations adoption of advanced AI capabilities. You will also contribute to the development of internal AI capabilities.
