As a Lead Infrastructure Engineer within the network services team, you will design, operate, and improve enterprise DNS and IPv6 capabilities. Your primary responsibilities include engineering IPv6 addressing plans using 128-bit formats, subnetting, and architecture patterns like GUA and ULA. You will implement reverse DNS delegation for IPv6 using ip6.arpa zones and execute transition approaches such as Dual-Stack, NAT64, and DNS64. Day-to-day tasks involve operating core DNS services, troubleshooting complex connectivity issues using dig and nslookup, and analyzing routing protocols like BGP and OSPFv3. You will automate operational tasks and utilize enterprise-authorized AI capabilities for infrastructure analysis. The role focuses on ensuring reliable name resolution, scalable network design, and measurable service outcomes across diverse hybrid environments while maintaining strict security and auditability standards.
