- 10+ years in network/infrastructure engineering with a strong focus on DNS, DHCP, and IPAM (DDI)
- Proven hands-on experience delivering DDI migrations at enterprise scale — multiple completed projects required
- Deep expertise in DNS architecture — split-horizon, forwarders, delegation, DNSSEC, recursive vs. authoritative
- Strong DHCP experience — scope design, failover/HA, relay configuration, lease management
- IPAM design and governance — IP hierarchies, subnet planning, utilization tracking
- Experience migrating from at least one of: Infoblox NIOS, Microsoft DNS/DHCP, BIND/ISC DHCP, or EfficientIP
- Scripting proficiency — Python or Bash for automation and bulk migration tasks
- Ability to produce high-quality technical documentation independently

Strongly Preferred

- Hands-on experience with BlueCat Integrity (Address Manager + BDDS) — configuration, administration, or migration
- Exposure to BlueCat Horizon DDI (cloud-native platform) — any level of familiarity valued
- Experience working within a partner or professional services delivery model (SI, managed services, or similar)
- Familiarity with BlueCat REST API for automation and integration workflows

Good to Have

- Cisco networking background — routing, switching, network segmentation in DDI-adjacent contexts
- Cloud DDI exposure — AWS Route 53, Azure DNS, or hybrid DDI architectures
- ITIL or project delivery framework experience
- Prior experience in a white-label or sub-contractor delivery model

Certifications

- BlueCat Certified (any level) — strongly preferred
- Infoblox Certified (NCSA / NCDDI) — relevant if transitioning from Infoblox environments
- Cisco CCNP / CCIE — advantageous
