A large, well-established global technology company with a dedicated AI Centre of Excellence - a team set apart from its core consulting and digital services divisions, focused purely on applied research and product builds using the latest Microsoft AI technology., You’ll join a close-knit team of around 10-11 engineers (the majority in Belfast, with others in Poland, Birmingham, and London) as a Senior AI Engineer, providing technical leadership on AI-powered products and applied research work. This isn’t a billable, consulting-style role - there’s no utilisation target and no client delivery pressure. The team is genuinely AI-first: they’re looking for strong, well-rounded engineers rather than candidates who tick every box, whether your background is more AI-shaped or more software-shaped.
