Senior DDI Engineer

Project Overview:

General tasks are to work as part of the migration team on a daily basis supporting migrations and operations / engineering tasks supporting the QIP and Bluecat environment through transition. Must work well in a team format. This resource will work with other supporting teams as well as business application owners as part of this work effort.

Key Responsibilities:

• Support migration, engineering, and operations work in the QIP and BlueCat environments throughout the transition.
• Run multi-pass migrations: export QIP data, write transformation scripts, and clean up orphaned records, inconsistent TTLs, overlapping IP blocks, and misconfigured DHCP options before import.
• Map QIP objects and custom properties to BlueCat’s object hierarchy and User-Defined Fields, then run bulk imports and validate the import logs.
• Manage DNS coexistence and query routing during the transition using BlueCat Edge or BIND forwarding rules, while keeping lookups to the legacy system working.
• Migrate DHCP scopes without IP conflicts by shortening legacy lease times before cutover and managing active lease hand-offs.
• Design and validate rollback and failback plans for each phased site cutover.
• Inventory custom QIP REST/SOAP integrations and rewrite them against BlueCat’s REST v2 API.
• Integrate BlueCat with Ansible, Terraform, and ServiceNow so automated provisioning keeps working after migration.
• Coordinate with supporting infrastructure teams and application owners.

Required Skills and Experience:

Mandatory:

• Senior-level DDI experience, with strong knowledge of QIP internals (objects, subnets, profiles, and its Sybase/Oracle database) and how it differs from native BIND.
• Strong knowledge of BlueCat Address Manager and BlueCat DNS/DHCP Server, including Configurations, Blocks, Subnets, Devices, and User-Defined Fields.
• Experience running stepped (multi-pass) data migrations, including data normalization and high-volume bulk imports.
• DNS coexistence and query routing during a dual-platform transition.
• DHCP lease migration strategy and rollback/failback planning.
• Advanced DNS: views, dynamic DNS across legacy and new servers, DNSSEC, and traffic monitoring.
• Scripting in Python, Bash, or PowerShell for data checks and delta merges.
• Linux appliance administration and BlueCat service deployment roles.
• Works well in a team and with application owners.

Nice to Have:

• API mapping from QIP to BlueCat: rewriting custom QIP REST/SOAP endpoints for BlueCat REST v2.
• DevOps and ITSM integration experience with Ansible, Terraform, and ServiceNow.
• Hybrid and multi-cloud DNS (AWS Route 53, Azure DNS), including avoiding IP overlap and forwarding sprawl.
• Prior large financial-services enterprise experience.
