Leading the platform's approach to data modelling, ontology strategy, semantic understanding, and business context required for AI-driven experiences. Providing architectural leadership across multiple engineering teams delivering AI, Integration, IoT, Connected Worker, and platform capabilities. Working closely with Product Management to align AI investments with customer needs, business objectives, and market opportunities. Establishing engineering standards for security, governance, observability, and responsible AI. Evaluating emerging AI technologies, frameworks, and architectural approaches. Mentoring engineers and acting as a technical authority for AI initiatives across the Manufacturing portfolio. Contributing to long-term technical strategy and roadmap planning for AI Acceleration initiatives. Basic Qualifications: A demonstrated background of software engineering experience delivering enterprise applications or platforms. Strong hands-on software development experience using modern engineering practices and technologies. Proven experience designing and delivering production AI solutions using Large Language Models (LLMs).
