Early Life and Background
Meg O’Neill was raised in Boulder, Colorado, a city known for its academic culture and proximity to scientific research institutions. Growing up in an environment that valued education and analytical thinking played a strong role in shaping her future ambitions. From an early age, she showed a natural aptitude for mathematics and problem-solving.

Education and Academic Foundation
Meg O’Neill studied at the Massachusetts Institute of Technology, one of the world’s most prestigious technical universities. She completed degrees in ocean engineering and chemical engineering, fields that demand precision, resilience, and deep analytical capability. Her academic training laid a strong foundation for a career in large-scale energy systems.
MIT also exposed her to global perspectives and interdisciplinary thinking. This combination of technical mastery and global awareness later enabled her to operate effectively across different regions, cultures, and regulatory environments.
Start of Career in the Energy Industry
Meg O’Neill began her professional career at ExxonMobil, where she entered as an engineer and steadily progressed through increasingly senior roles. Her early work focused on offshore modelling and reservoir engineering, giving her first-hand exposure to the operational realities of oil and gas production.
Unlike many executives who move quickly into corporate roles, she spent significant time in technical and field-based positions. This practical experience earned her credibility with engineering teams and shaped her reputation as a leader who understands operations from the ground up.
Global Career Growth at ExxonMobil
During her long tenure at ExxonMobil, meg o’neill worked across multiple regions including North America, Southeast Asia, Europe, and Africa. She held leadership roles in Indonesia, Canada, and Norway, managing complex projects in challenging environments.
Her career progression culminated in senior executive responsibilities, including serving as vice president overseeing major African developments. This period strengthened her ability to manage geopolitical risk, large capital investments, and cross-border stakeholder relationships, all of which would later define her executive leadership.
Transition to Woodside Energy
In 2018, Meg O’Neill joined Woodside Energy as Chief Operating Officer, marking a significant transition from a long-established career at ExxonMobil. Her appointment signalled Woodside’s intention to strengthen operational discipline and global competitiveness.
