OpenAI said it is adding 200 roles in Dublin and building a second applied AI lab at its European headquarters, taking planned Irish hiring to 450. The positions include forward deployed, solutions and privacy engineers plus sales and user operations staff, following 250 roles announced in July when the company leased 88,000 square feet at the Tropical Fruit Warehouse in the Docklands, with occupancy from December. The lab is a deployment unit rather than a research one, pairing engineers with customers building on OpenAI's existing models; the first opened in Singapore in May with a S$300 million (about $235 million) commitment and roughly 200 planned staff, while OpenAI published no equivalent figure for Dublin.
