The current Chairman, President, and CEO of Exxon Mobil Corporation, positions previously held by Lee Raymond.

Tillerson graduated from Huntsville High School, Huntsville, Texas, in 1970. He received a Bachelor of Science in civil engineering from the University of Texas at Austin in 1975. During his time at UT Austin, he was involved with the Tejas Club, Longhorn Band, and Alpha Phi Omega. In 2006 he was named a Distinguished Engineering Graduate.

Tillerson joined The Exxon Company, US, in 1975 as an engineer. He held various positions with Exxon, domestically and internationally. In 1995, he became president of Exxon Yemen Inc. and Esso Exploration and Production Khorat Inc. In 1998, he became a vice president of Exxon Ventures (CIS) and president of Exxon Neftegas Limited with responsibility for Exxon's holdings in Russia and the Caspian Sea. In 1999, with the merger of Exxon and Mobil, he was named Executive Vice President of ExxonMobil Development Company.

In 2004, he became president and director of Exxon Mobil and on January 1, 2006, he was elected chairman and chief executive officer (CEO), following the retirement of Lee Raymond. Tillerson is also a trustee for the centre for Strategic and International Studies and the American Petroleum Institute, and is a member of the Business Roundtable.

Tillerson recently re-established his authority during a shareholder meeting on May 28, 2008. The Rockefeller family sponsored a non-binding resolution to separate the CEO and chairman positions that Tillerson holds in order to maintain a system of cheques and balances. The Rockefeller family also wanted Exxon Mobil to invest more in alternative energy. The resolution did not obtain the necessary majority and Tillerson held on to both job titles.

In 2009, Exxon Mobil acquired XTO Energy, a major natural gas producer, for $31 billion in stock. Some writers have stated that "Tillerson's legacy rides on the XTO Deal.".

In 2011 Tillerson signed an agreement with Russia, for drilling in the Arctic, that could be valued up to $300 billion.

He is a member of the Executive Committee of The Business Council for 2011 and 2012.

Tillerson is married and has four children. He lives in Irving, Texas.
