General Charles Chiec Mayor is a high-ranking South Sudanese security official who holds two significant leadership roles in the country's communications and intelligence sectors:

**📡 Board Member, National Communications Authority (NCA)**
As a member of the NCA board, he helps guide South Sudan’s telecom and ICT regulatory body—the authority that oversees licensing, spectrum allocation, consumer protection, and promotes communication infrastructure development. The board sets the strategic and regulatory policymaking direction for national communications.

**🔐 Director General, Internal Security Bureau (ISB) – National Security Service (NSS)**
On February 10, 2025, President Salva Kiir confirmed Major‑General Charles Chiec Mayor as the permanent Director General of the NSS’s Internal Security Bureau. He had previously served as Deputy Director General for Administration & Finance, and was acting head for about a week following the firing of his predecessor; on February 17 he was formally promoted to full general and took the helm of the bureau.

In his intelligence role, Gen. Mayor leads one of South Sudan’s most powerful security agencies—one which holds broad authority, including warrantless arrests—and which has faced criticism over crackdowns on opposition figures, activists, and journalists. His dual roles—regulatory board member and spy chief—highlight his significant influence across both communication oversight and national security operations.
