SUMMARY

The Senior Systems Engineer is a senior technical contributor responsible for advanced server and systems implementation, troubleshooting, and escalation support across a diverse client base within a remote MSP environment. This role handles complex infrastructure incidents escalated from Tier 1, drives proactive improvements, and serves as a subject matter expert for Windows and Linux server administration, virtualization, identity, storage, backup, and cloud platforms. The engineer works closely with clients and internal teams to deliver high-quality, reliable managed services, and is expected to use AI tools to work faster and raise the quality of their work.

JOB RESPONSIBILITIES

• Administer and troubleshoot Microsoft Active Directory, Group Policy, DNS, DHCP, ADFS, and Remote Desktop Services, including forest and domain architecture, trusts, replication, and FSMO roles.
• Manage and optimize virtualization platforms including VMware vSphere (ESXi, vCenter, vSAN), Microsoft Hyper-V (failover clustering, live migration), and Nutanix HCI (AHV, Prism).
• Administer Microsoft 365 (Exchange Online, SharePoint, Teams, Entra ID) and hybrid identity configurations.
• Support and troubleshoot cloud workloads in AWS and Azure, including IaaS, PaaS, and hybrid architectures.

• Lead advanced troubleshooting and root cause analysis for complex server, virtualization, identity, and performance issues.
• Lead patching, firmware upgrades, and lifecycle management for servers and infrastructure appliances across the client base.
• Develop and maintain monitoring strategies using LogicMonitor or equivalent platforms; create custom alerts and dashboards and remediate issues before client impact.
• Manage and resolve escalated tickets within MSP platforms (ConnectWise, Dell Kace, FreshService); document resolutions thoroughly.
• Conduct system assessments and assist with architecture diagrams, runbooks, and technical documentation for client environments.
• Conduct periodic security posture reviews including vulnerability assessments, configuration audits, and hardening recommendations aligned to NIST, CIS, or client-specific frameworks.
• Use AI tools to accelerate troubleshooting, scripting, documentation, and research, while reviewing AI output for accuracy before applying it in client environments.
• Build automation and scripts (PowerShell, Python, Bash) to reduce manual effort and improve consistency, including AI-assisted script development.
• Evaluate emerging platforms, tooling, and AI-driven capabilities on behalf of the MSP and recommend adoption into the standard service stack.

Support & Operations

• Serve as the primary escalation point for server and systems incidents; own resolution from escalation through closure.
• Act as primary escalation for P1 and P2 outages, coordinating with cross-functional teams and keeping management and stakeholders informed.
• Lead change management activities including planning, scheduling, implementing, and validating production changes.
• Participate in on-call rotation and after-hours maintenance windows as required.
• Collaborate with hardware vendors, software vendors, and cloud providers to coordinate RMAs, support cases, and complex issue resolution.
• Assist in onboarding new MSP clients including discovery, documentation, and transition planning.
• Identify recurring issues and drive proactive improvements to reduce incident volume and improve client stability.
