Fractional Senior Infrastructure

What We Offer

At Convverge, we build business‑level solutions using Microsoft technology to solve complex problems for our clients.

We’re a close‑knitted, high‑trust team that values technical quality, ownership, and practical problem solving. Our people are trusted to make good decisions, take accountability for outcomes, and work collaboratively across disciplines.

We’re looking to add senior technical depth to our team through a fractional role that combines hands‑on engineering, solution design, technical leadership, and knowledge transfer.

About the Role

Convverge is looking for an experienced Fractional Senior Infrastructure & Cloud Engineer to provide senior‑level technical expertise across our client environments.

This is a hands‑on fractional role designed to complement our existing technical team by providing deeper expertise across Microsoft cloud, infrastructure, networking, security, and complex technical troubleshooting.

You’ll step in where senior technical depth is required, whether that means resolving a difficult Tier 3 escalation, designing an Azure Virtual Desktop environment, reviewing a client’s security posture, supporting a migration, or helping determine the right technical approach to a complex infrastructure problem.

This is not a traditional help desk position. Your focus will be on the problems and projects where experience, judgment, and technical depth matter most.

Just as importantly, we want this role to strengthen the capability of the team around you. A key part of the mandate is to solve, document, teach, and standardize so that knowledge is shared rather than concentrated.

What You’ll Do

• Senior Technical Escalation
  • Serve as a senior escalation resource for complex Tier 3 issues across Microsoft 365, Azure, identity, endpoints, networks, and infrastructure.
  • Diagnose complex, multi‑layered technical problems and lead root‑cause analysis.
  • Take ownership of issues that require deeper technical investigation or experience.
  • Identify and implement permanent solutions rather than relying on temporary workarounds.
  • Collaborate with internal technical resources and third‑party vendors while maintaining ownership of technical outcomes.
• Microsoft 365, Identity & Endpoint Management
  • Architect, deploy, administer, and troubleshoot Microsoft Entra ID, Microsoft Intune, Microsoft Defender, and Microsoft 365 environments.
  • Design and implement Conditional Access, MFA, compliance policies, configuration standards, and security baselines.
  • Support Microsoft 365 tenant migrations, licensing initiatives, security assessments, and environment improvements.
  • Troubleshoot complex endpoint and device‑management issues across Windows, macOS, iOS, and Android.
  • Review Microsoft security posture and recommend practical improvements using Secure Score and applicable Microsoft security practices.
• Azure & Azure Virtual Desktop
  • Design, deploy, administer, and troubleshoot Azure Virtual Desktop environments.
  • Provide senior technical guidance on AVD architecture, security, capacity, performance, and reliability.
  • Support Azure infrastructure including virtual machines, networking, storage, and identity integration.
  • Troubleshoot complex Azure infrastructure and connectivity issues.
  • Support migration and modernization initiatives involving on‑premises and Azure‑hosted workloads.
• Infrastructure & Networking
  • Provide senior‑level expertise across Windows Server, Active Directory, Group Policy, DNS, DHCP, file services, Hyper‑V, VMware, backup, and disaster recovery technologies.
  • Design, deploy, and troubleshoot network infrastructure including firewalls, VLANs, VPNs, site‑to‑site connectivity, wireless networks, routing, and switching.
  • Perform advanced network troubleshooting and root‑cause analysis.
  • Support infrastructure security hardening and network segmentation initiatives.
  • Help ensure environments are reliable, secure, performant, and supportable.
• Solution Design & Project Delivery
  • Participate in technical discovery, solution design, and client technical reviews.
  • Translate client requirements into practical technical solutions.
  • Review proposed solutions and identify risks, dependencies, security considerations, and operational impacts before implementation.
  • Lead or support infrastructure and cloud projects from design through implementation and handoff.
  • Provide senior engineering support during migrations and complex technical implementations.
  • Establish repeatable technical standards and approaches that can be applied across client environments.
• Security
  • Incorporate security into infrastructure, identity, endpoint, networking, and cloud
