Role Overview

About White Oak Solutions

White Oak Solutions is a cybersecurity consulting and managed services firm serving mid-market, regulated, and defense-adjacent clients. Our engagements span security operations, network and infrastructure architecture, compliance (including CMMC), and ongoing managed services. We are in a period of deliberate growth and are expanding our professional services practice with senior technical talent who can both deliver and help win the work.

The Infrastructure Architect is a senior, client-facing technologist who owns infrastructure solutions end to end — from pre-sales discovery and design through implementation, handoff, and ongoing advisory. The role sits at the center of our professional services practice: scoping and architecting Microsoft- and VMware-based environments, hybrid and public cloud (Azure and AWS), and the server, storage, and virtualization platforms underneath them.

This is a billable, delivery-leading position with a meaningful sales-engineering component. You will lead engagements, mentor engineers, shape statements of work, and act as a trusted advisor to client executives and technical staff alike. Experience inside a managed services provider — where you have lived with the environments you designed — is central to how we expect this person to think.

Key Responsibilities

Pre-sales and solution development

• Partner with sales and leadership on discovery, whiteboarding, and solution design for prospective and existing clients
• Develop architectures, bills of materials, level-of-effort estimates, and statements of work; present and defend designs to technical and executive audiences
• Support proposals, RFP responses, and vendor/licensing selection (including partner pricing programs)
• Provides objective consultation to our clients for the selection and adoption of infrastructure-related managed services.

Professional services delivery

• Lead infrastructure engagements from kickoff through closeout: migrations, upgrades, greenfield builds, virtualization and storage projects, and cloud adoption/modernization
• Serve as technical lead and escalation point for project engineers; enforce design, documentation, and change-management standards
• Produce client-ready deliverables: architecture documents, runbooks, as-builts, and assessment reports

Post-sales and managed services

• Own post-implementation transition into managed services: handoff documentation, monitoring/alerting onboarding, and operational acceptance
• Conduct periodic architecture reviews, health checks, and roadmap/lifecycle planning for managed clients
• Act as escalation resource for complex infrastructure incidents and root-cause analysis

Practice development

• Help standardize reference architectures, service offerings, and delivery methodology for the infrastructure practice
• Maintain vendor relationships and certifications aligned to our partner ecosystem
• Mentor engineers and contribute to internal knowledge management
• Helps enable the sales team for opportunity recognition, service and solution provider intelligence and guidance, and provide technical input to the sales process

Required Qualifications

• 10+ years in infrastructure engineering/architecture, with at least 3 in an architect or technical-lead role
• Deep, hands‑on expertise with Microsoft infrastructure: Windows Server, Active Directory, Entra ID, Exchange/M365 integration, Group Policy, and related identity and management tooling
• Deep expertise with VMware (vSphere, vCenter, vSAN or equivalent storage integration), including design, migration, and lifecycle/licensing realities of the current VMware landscape
• Strong background in server and storage platforms (SAN/NAS, HCI, backup/DR architectures) from major vendors
• Production experience architecting and migrating workloads in both Azure and AWS — IaaS, identity, networking, storage, and cost/licensing considerations; hybrid designs a must
• Demonstrated leadership of professional services engagements: scoping, estimating, leading delivery teams, and owning client outcomes
• Proven pre-sales ability (discovery, solution design, proposal support, executive presentation) alongside post-sales delivery and support
• Prior experience at or with a managed services provider, and fluency in MSP operating models (tooling, SLAs, escalation tiers, service transitions)
• Strong written communication — this role produces client‑facing architecture and assessment deliverables
• Ability to obtain and maintain applicable client access requirements; some clients operate in regulated and defense‑adjacent environments

Preferred Qualifications

• Relevant certifications: Microsoft (Azure Solutions Architect Expert, Windows Server Hybrid Administrator), VMware (VCP/VCAP), AWS (Solutions Architect Associate/Professional), or equivalent demonstrated depth
• Exposure to network and security ecosystems we work in daily: Fortinet, Palo Alto Networks, Cisco, HPE/Aruba, and SASE platforms such as Cato Networks
• Experience supporting compliance-driven environments (CMMC, NIST 800-171, SOC 2, HIPAA) and designing infrastructure to control requirements
• Familiarity with infrastructure automation and tooling (PowerShell, Terraform, or similar) and with modern backup/DR platforms
• Experience with VMware-alternative hypervisors (Hyper‑V, Proxmox, Nutanix AHV) as clients evaluate post‑Broadcom options
• Prior work in a VAR/consultancy comp model with utilization or sales‑influenced incentives

Location and Travel

• Remote within the United States. Travel to client sites and company offices as engagements require. Candidates in or near the Southeast are a plus given our client footprint, but not required.
