About TURNBRIDGE

TURNBRIDGE delivers precision-driven technical solutions and talent strategies that accelerate outcomes. We prioritize quality over volume—clear requirements, fast shortlists, and experts who can execute with minimal overhead. Our teams are trusted to step into complex environments, bring structure, and leave systems stronger than we found them.

Role Overview

TURNBRIDGE is seeking an experienced Infoblox Architect to own an end-to-end DDI modernization and migration effort. This engagement requires a hands-on infrastructure engineer who can pick up a partially completed migration, quickly assess the current state, confirm the target architecture, and drive implementation through completion—without day-to-day supervision.

This is not a “split-focus” role. The successful contractor will be dedicated to delivering a stable, supportable Infoblox-centric DDI platform, integrating with automation workflows, and producing handoff-ready documentation and SOPs for a permanent team.

What You’ll Be Responsible For

Infoblox DDI Architecture & Migration

Perform an architecture review of the current DDI landscape and migration approach; resolve open design questions before implementation begins.

Design, implement, and maintain Infoblox DDI services (DNS, DHCP, IPAM) across multiple networks/environments.

Administer Infoblox Grid operations including HA, RBAC, logging/monitoring, upgrade planning, and operational hardening.

Migrate internal DNS authority from Windows-based services to Infoblox (including zone strategy, delegation, forward/reverse zones, and naming standards).

Lead DHCP migration from Windows to Infoblox, including scope cleanup, cutover planning, and rollback considerations.

Establish Infoblox as the system of record for IPAM, replacing spreadsheet-based workflows.

Core Infrastructure & Platform Engineering

Administer and optimize Nutanix HCI (cluster configuration, storage, performance tuning, capacity planning, troubleshooting).

Install/configure/maintain Windows Server (2016/2019/2022+) including core roles/services as applicable (AD integration, DNS dependencies, file/print where relevant).

Monitor infrastructure health and availability; proactively identify bottlenecks and implement corrective actions.

Troubleshoot complex incidents spanning Infoblox, Windows Server, DNS, DHCP, networking fundamentals, and upstream/downstream dependencies.

Participate in on-call rotation as required for production stability.

Automation, Security, and Operational Excellence

Integrate Infoblox APIs into existing Ansible / Red Hat AAP provisioning workflows to enable self-contained builds (IP reservation + DNS updates included).

Implement security best practices: patching, hardening, vulnerability remediation, and compliance alignment.

Create and maintain runbooks, architecture diagrams, SOPs, and operational documentation to ensure long-term transferability.

Collaborate with network, security, application, and service desk teams to ensure dependable service delivery.

Current Environment (High-Level)

You’ll be working in a mature enterprise environment with accumulated DDI complexity, including:

Internal DNS: Windows Active Directory authoritative; Infoblox currently receiving/synchronizing data

External DNS: Currently on Infoblox for a separate domain; moving to Cloudflare (already deployed)

DHCP: Windows-based; migrating to Infoblox

IPAM: Spreadsheet-based; migrating to Infoblox

Infoblox Platform: Physical appliances approaching/at EOL; migrating to vNIOS (in the same data center)

Cloud/Hybrid: An Azure domain controller handling DNS planned for decommission during the migration

Automation: Ansible + Red Hat AAP in place; Infoblox API integration planned

DNS Security: Infoblox Threat Defense deployed; active support contract

Branch/Remote Locations: SD-WAN in place; DNS caching considerations are a lower-priority item

Auth: Active Directory LDAP integration for Infoblox authentication is already established

Not in Scope: GSLB/SLB

Key Deliverables / Outcomes

The engagement will be considered successful when the contractor delivers:

Architecture review summary with validated migration plan and sequencing (DNS, DHCP cleanup, vNIOS path, Azure DC decommission sequencing).

Internal DNS migration completed with authority moved to Infoblox and dependencies stabilized.

DHCP cutover completed with scope cleanup and reliable HA/operations.

IPAM implemented in Infoblox as the system of record (spreadsheet retired).

Automation integrated: Ansible/AAP provisioning includes IP reservation + DNS updates via Infoblox APIs.

Physical-to-vNIOS migration completed with performance and resiliency validated.

External DNS transition completed (Cloudflare cutover) while maintaining DNS security continuity.

Handoff-ready documentation: runbooks, SOPs, diagrams, and operational checklists.

Required Qualifications

Proven experience as an Infrastructure/Operations Engineer or Architect owning core platforms end-to-end.

Deep, hands-on experience administering Infoblox DDI (DNS/DHCP/IPAM), including Grid management, HA, RBAC, and operational best practices.

Strong expertise in DNS concepts and operations: record/zone types, conditional forwarders, split-brain DNS, delegation, reverse lookup zones, and troubleshooting.

Solid experience with Windows Server (2016/2019/2022+): install/configure, patching, tuning, and integration with directory services.

Strong working knowledge of networking fundamentals (TCP/IP, VLANs, routing, firewalls, load balancers) as they relate to DDI and virtual infrastructure.

Experience with Nutanix HCI (AOS/Prism/AHV or hypervisor operations), including troubleshooting and capacity planning.

Automation/scripting expertise with PowerShell and Ansible (Red Hat AAP experience strongly valued).

Strong troubleshooting ability using logs, traces, and metrics to drive root cause resolution.

Excellent documentation and stakeholder communication skills.

Preferred Qualifications

Infoblox certifications (e.g., NIOS/DIW or related) or equivalent demonstrable experience.

Experience implementing/operating Infoblox Threat Defense.

Experience planning/operating DNS transitions involving Cloudflare.

Familiarity with monitoring/logging platforms for infrastructure observability.

Experience designing scalable DDI for multi-site/branch environments (including DNS caching strategies).
