Rubens Kühl was the Product Marketing Manager at NIC.br and Registro.br. He worked in the ICT and Internet infrastructure sectors for more than 15 years, attended ICANN meetings since ICANN 42 (Dakar), and frequently engaged with the network-operator community.[1] Kühl served on the GNSO Council between 2016–2019, taking part in the work that initiated the EPDP on the Temporary Specification.[2] He remained active beyond his Council term, including membership on the "GNSO Guidance Process (GGP) Initiation Request – Select SubPro Topics (Applicant Support)" team[3]. He passed away on 3 November 2025 at age 55, with NIC.br announced his death while highlighting his years of service to the Brazilian and international community.[4]
Career edit
Kühl began his career in network engineering and security at UOL (1998–2002) and later worked at Scopus Tecnologia, with consulting engagements at RKJ and Multirede.[5] He moved into backbone operations at Neovia Telecom (2006–2009), working on TCP/IP and MPLS practices and the commissioning of new technologies.[5]
He joined NIC.br in 2009, first on broadband/product development, and from 2011 served as Product & Market (Product Marketing Manager) for Registro.br. In that role he worked on product and market strategy, registrar channels, DNSSEC adoption and outreach, and the reliability and branding of the .br registry services.[6] He also taught at CGI.br’s Escola de Governança da Internet from 2014 onward.[6]
Beyond the DNS space, he took part in early community discussions and testing around Brazil’s instant payments system **PIX**—commenting on technical/market implications, moderating Q&A on security and adoption, and reporting hands-on tests at launch.[7][8][9]
Education edit
Kühl held an Executive MBA in Marketing from Escola Superior de Propaganda e Marketing (ESPM); a Graduate Certificate in Telecommunications Economics from Universidade de São Paulo; and a BS in Computer Engineering from Universidade de São Paulo.[5]
Personal edit
In the Brazilian community, Kühl was affectionately known by some friends as “Mestre dos Magos” (the “Dungeon Master” from the Dungeons & Dragons cartoon), a nod to his vast knowledge, sharpness, and dry humor.[10]
