Role Posting Log in to save

As a Lead Infrastructure Engineer within the Enterprise Technology network services team, you will design, operate, and improve enterprise DNS and IPv6 capabilities to ensure reliability and security. You will build scalable name resolution architectures for hybrid environments, engineer 128-bit IPv6 addressing plans using GUA and ULA formats, and implement reverse DNS delegation via ip6.arpa zones. Your daily work involves executing transition strategies like Dual-Stack, NAT64, and DNS64 while troubleshooting complex connectivity issues using dig and nslookup across A and AAAA paths. You will automate operational tasks, analyze routing protocols such as BGP and OSPFv3, and utilize enterprise-authorized AI capabilities to accelerate infrastructure analysis. The role focuses on solving critical network reachability and name resolution challenges while maintaining high availability through disciplined diagnostics and documented playbooks in a complex networking environment.
