Hussein Shil, CTO of AWS Energy and Utilities, shares a career defined by curiosity, reinvention, and the ability to translate complex business problems into real technology outcomes. Originally from Lebanon, Hussein moved to New York as a student with limited connections and an intense drive to build a future through education and work ethic. He adapted quickly, navigating a new system, learning independence fast, and developing the mindset that would later define his leadership: stay solution-oriented, keep learning, and never wait for perfect conditions. Early on, a small company took a chance on him, giving him broad, hands-on exposure that shaped how he thinks about value creation—own the problem, figure it out, and deliver. That foundation carried him into Chevron, where he spent 11 years embedded alongside engineers and business teams, building credibility by understanding what the business truly needed and using technology to make it better. He later moved to Microsoft, where he held multiple senior leadership roles including CTO of Energy driving innovation and partnerships with major energy customers, before joining AWS to lead strategy, technology, and subsurface transformation across the Energy and Utilities business.
