Sayyid Ahmad Obaid was initially named as the communications battlefield coordinator in King Abdulaziz military campaign in the Saudi-Yemeni War that culminated in the Treaty of Taif (1934) that officially incorporated Jizan, Asir, and Najran into modern Saudi Arabia. He was then named as a senior inspector in the Ministry of Finance directly reporting to King Abdulaziz's finance minister, Abdullah bin Suleiman Al Hamdan, and dispatched to the northern and southern border regions of the Kingdom to establish customs offices at the new Saudi entry points with Yemen, Kuwait, and Iraq. He was subsequently named as the Saudi financial &amp; customs attache to pre-independence Kuwait (before formal diplomatic ties were established), then director general of the Finance Ministry, and when the first Saudi Council of Ministers was formed in 1953, he was named the deputy minister in the newly formed Agriculture Ministry to its first minister, former Crown Prince Sultan bin Abdulaziz Al Saud. After more than twenty years in public service, he retired in 1955.
