About T3 Tech Partners

T3 Tech Partners is the team MSPs rely on when challenges exceed Tier 2 or internal expertise. We operate as a Fractional Tier 3 partner, delivering advanced Microsoft 365, cloud, and security expertise to MSPs supporting diverse client environments.
Our engineers are trusted technical partners — leading implementations, resolving complex escalations, and working directly with MSP clients to execute real-world solutions.
________________________________________
Role Overview
We are seeking a senior-level Cloud Solutions Engineer (Level 3) to lead advanced Microsoft 365 and cloud initiatives, handle complex escalations, and implement solutions directly with MSP clients. This is a technical, customer-facing role — while not sales-focused, you will regularly work directly with customers to design and implement the solutions required to meet their business and technical needs.
This role requires strong technical depth, independence, and the ability to step into unfamiliar environments and software ecosystems with confidence.

Key Responsibilities
Advanced Cloud & Escalation Support
• Handle advanced and expert-level escalations related to cloud infrastructure and SaaS services.
• Serve as a senior escalation point for Microsoft 365 and cloud-related issues across multiple MSP environments.
• Perform root-cause analysis and implement long-term remediation for complex or recurring issues.
• Work directly with MSP clients and end customers to execute solutions and improvements.

Microsoft 365 (Core Focus Area)
• Architect, deploy, optimize, and support Microsoft 365 environments end-to-end, including:
o Exchange Online (mail flow, security, migrations, troubleshooting)
o SharePoint Online and OneDrive (architecture, permissions, governance, performance, migrations)
o Microsoft Teams (policies, governance, troubleshooting)
• Perform and lead tenant-to-tenant migrations, including email, OneDrive, SharePoint, and Teams data.
• Execute server-to-cloud migrations, such as file servers to SharePoint or OneDrive.
• Expert-level administration and troubleshooting of:
o Microsoft Intune (endpoint management, compliance policies, configuration profiles, application deployment, Autopilot)
o Microsoft Entra ID (Azure AD) including identity lifecycle, SSO, MFA, and hybrid identity
o Conditional Access policy design and enforcement
o Microsoft Defender (Endpoint, Office 365, Identity)
o Microsoft Purview (data governance, retention, compliance, DLP)
• Implement and maintain Microsoft 365 security best practices across client tenants.
• Assist MSPs with tenant configuration, licensing strategy, and feature utilization.

Third-Party Application Integration
• Work with third-party software applications that integrate with Microsoft 365 (email, identity, security, document management, line-of-business platforms).
• Support applications you may not have prior experience with, requiring:
o Willingness to learn new platforms quickly
o Ability to understand how third-party systems interact with Microsoft 365
o Troubleshooting authentication, permissions, data flow, and integration issues
• Collaborate with vendors and MSPs to ensure proper configuration and supportability.

Server and Infrastructure Support
• Administer and troubleshoot Windows Server environments, including Active Directory, DNS, DHCP, Group Policy, and File Services.
• Manage and support virtualization platforms (e.g., Hyper-V, VMware) in on-premises and hybrid configurations.
• Perform server migrations, including lift-and-shift to Azure, P2V conversions, and workload transitions to cloud-hosted services.
• Support and maintain backup and disaster recovery solutions, ensuring recoverability for both on-premises and cloud workloads.
• Assist with decommissioning legacy on-premises infrastructure as part of cloud migration projects.

Projects, Optimization & Automation
• Lead cloud migration and optimization projects for MSP clients.
• Optimize Microsoft 365 environments for security, performance, and cost efficiency.
• Develop and maintain PowerShell scripts to automate Microsoft 365, Entra ID, Intune, and related administrative tasks.
• Recommend improvements, standards, and long-term strategies to MSP partners.
• Stay current on Microsoft 365 feature changes and emerging cloud technologies.
Availability & Support Expectations
• Standard working hours are 9:00 AM–5:00 PM EST.
• Some flexibility is required for high-impact client issues, critical changes, or migrations outside normal hours.
• This role is not on-call, but responsiveness during critical events is expected.
