Are you passionate about helping customers achieve business transformation through AI? Do you want to lead forward-deployed teams that embed directly into the enterprise and unlock real business outcomes? And are you ready to operate as a general manager across engineering, science, and commercial strategy in the fastest-moving space in AI and infrastructure? The AWS Generative AI Innovation Center (GenAIIC) is on a mission to accelerate enterprise AI transformation across global customers going from beyond isolated use cases to holistic, C-suite-sponsored initiatives that reshape how organizations operate. We combine deep AI expertise across science, strategy, and business transformation. We start with the customer's most critical operational challenges and work backwards, and deploy multidisciplinary teams that embed with the customer, prove impact in 45-day sprints, and expand across the enterprise. We are a fast-moving, entrepreneurial team that values leaders who can operate across technical depth and commercial breadth. As the Head of AI Transformation, GenAIIC APJC Geo, you will own the end-to-end success of AI transformation engagements across the Asia Pacific, Japan, and Greater China region. You will lead a team of ML engineers, AI scientists, and AI strategists who work alongside customers to architect and deliver AI solutions that move and stay in production, realizing value. You will regularly engage with CFOs, CIOs, and C-suite executives — selling transformation, not technology. You must bring a GM mindset: equal fluency in engineering, applied science, go-to-market, and customer delivery. You are ready to roll up your sleeves alongside the team — whether that means scoping an agentic AI architecture, presenting to a board, or operationalizing a repeatable delivery motion across geos. You will partner with customers, AWS Sales, AWS service teams, AWS industry teams and AWS Professional Services delivery teams to meet the specific needs of the customer, and extend that use to other customers. Key job responsibilities Lead a high-performing, multidisciplinary team of ML engineers, AI scientists and strategists. Own the regional engagement pipeline — identify, qualify, and land C-suite-sponsored AI transformation programs with enterprise customers. Guide the team in designing, building, and deploying production AI solutions. Drive a land-and-expand motion: prove value in focused sprints, then scale across business units with executive sponsorship. Operate as a GM — balancing technical delivery, talent development, commercial outcomes, and operational excellence. Advise and influence customers on enterprise AI strategy, including architecture decisions, organizational readiness, and change management. Drive adoption of AWS generative AI services by delivering AI expertise and developing repeatable transformation playbooks. Develop new strategies and mechanisms to address evolving customer needs while increasing business velocity and impact for AWS. Influence product roadmap with service teams based on customer feedback. A day in the life Diverse Experiences AWS values diverse experiences.
