DDI Engineer

Hi,

Hope you are doing well.

Position: Sr. DDI Engineer / DNS-DHCP-IPAM Engineer

Location: Chicago, IL (Onsite)

Job Description:

We are seeking a highly skilled DDI Engineer to join our Foundational Services organization. This role will focus on designing, engineering, and enhancing enterprise-scale DNS, DHCP, and IP Address Management (DDI) solutions across hybrid environments, including on-premises infrastructure and cloud platforms such as AWS Route 53 and Azure DNS.

The ideal candidate will have a strong engineering and architecture background with experience designing and implementing large-scale network services. This is not a traditional support role; we are looking for someone who can provide technical vision, define future-state architecture, drive automation, and help shape the long-term strategy for DDI services.

Key Responsibilities

• Design, engineer, and enhance enterprise DDI solutions supporting hybrid environments across on-premises infrastructure and cloud platforms.
• Develop and maintain DNS/DHCP/IPAM architectures using technologies such as Infoblox, BlueCat, AWS Route 53, and Azure DNS.
• Define future-state DDI vision, architecture standards, and technology roadmaps.
• Automate DDI workflows using tools and technologies such as Python, Ansible, APIs, and CI/CD pipelines.
• Implement automation solutions for provisioning, zone management, synchronization, compliance validation, and operational efficiency.
• Partner with Network, Cloud, Security, and Infrastructure teams to design scalable and resilient solutions.
• Troubleshoot complex DNS, DHCP, and IPAM issues, perform root cause analysis, and deliver long-term corrective solutions.
• Lead technical investigations for high-priority incidents and network-impacting issues.
• Establish technical standards, review security updates and vulnerabilities, and recommend mitigation strategies.
• Create and maintain technical documentation, architecture diagrams, runbooks, and operational procedures.
• Serve as a subject matter expert for DDI technologies and contribute to enterprise technology strategy.

Required Qualifications

• 5+ years of experience in network engineering, DDI engineering, or infrastructure architecture roles.
• Strong hands-on experience with DNS, DHCP, and IP Address Management (DDI) technologies.
• Experience working with enterprise DDI platforms such as:
• Infoblox
• BlueCat
• Similar DDI solutions
• Experience designing and managing DNS solutions in hybrid environments.
• Experience with cloud DNS services such as:
• AWS Route 53
• Azure DNS
• Strong understanding of network architecture, DNS resolution, zone delegation, and IP management concepts.
• Experience with automation and scripting using:
• Python
• Ansible
• REST APIs
• Experience supporting large-scale enterprise environments (1,000+ users or equivalent infrastructure scale).
• Experience working in engineering or architecture roles rather than primarily operational support roles.

Preferred Qualifications

• Experience developing enterprise network architecture and technology roadmaps.
• Experience with Active Directory integration and enterprise identity services.
• Experience with software-defined infrastructure and cloud networking.
• Knowledge of security practices related to DNS, DHCP, and network services.
• Experience working with cross-functional technology teams and external vendors.
• Strong communication skills with the ability to influence technical
