• Ensure secure DNS and IP management, including Active Directory integration and authentication
• Collaborate with network teams on routing and switching engineering (BGP, OSPF) to support DNS resiliency

• Act as the technical SME and escalation point for all DDI-related matters

Requirements

DDI SME

This role calls for a hands-on DDI Subject Matter Expert with deep expertise in DNS, DHCP, and IPAM. It is not purely strategic; the position requires the ability to design, build, integrate, and take end-to-end ownership of DDI initiatives across a diverse ecosystem. The focus is on driving modernization, automation, and observability while ensuring scalability and security. A key responsibility is also to lead a comprehensive resilience assessment and provide informed recommendations to the bank based on the findings.

• 15+ years of progressive experience in DDI (DNS, DHCP, IPAM), including leading large-scale enterprise deployments, transformations and resilience initiatives
• Strong hands-on experience with DDI platforms (Infoblox, Cygna Labs/QIP, EfficientIP, or similar)
• Deep understanding of DNS architecture, design, and operations
• Experience with Anycast DNS deployments in enterprise or large-scale environments
• Solid understanding of networking protocols, especially BGP and OSPF
• Knowledge of DNS observability tools (DNS Tap, logging, telemetry pipelines)
• Experience integrating DDI with Active Directory and secure authentication mechanisms
• Familiarity with compliance, governance, and control frameworks in network services
• Strong troubleshooting and problem-solving skills in complex, distributed environments

Nice to Have

• Experience with DDI automation (Python, APIs, Ansible, Terraform)
• Exposure to cloud-based DNS architectures (AWS Route 53, Azure DNS)
• Experience with high-availability, globally distributed DNS systems
• Knowledge of DNS security best practices (DNSSEC, DDoS mitigation)
