Position Overview
PCS is seeking an experienced Tier III IT Systems Engineer to lead the management and optimization of client infrastructure environments.
This position serves as both a senior technical escalation point and a hands-on engineer, responsible for designing, maintaining, and troubleshooting servers, networks, and cloud platforms across multiple clients.
The ideal candidate thrives in diverse, multi-site environments, possesses deep expertise across infrastructure disciplines, and demonstrates strong diagnostic, design, and leadership capabilities.
Key Responsibilities
Client Systems & Network Administration
- Own the ongoing operation, optimization, and lifecycle management of client infrastructure — including servers, networks, storage, and cloud platforms.
- Administer and troubleshoot Windows Server (2016–2022) environments, Active Directory, DNS, DHCP, and Group Policy across multi-domain infrastructures.
- Architect, configure, and maintain network equipment — firewalls, routers, switches, wireless controllers (Cisco, Fortinet, SonicWall, Unifi).
- Manage VPNs, VLANs, QoS, and advanced routing for secure and performant connectivity between client sites.
- Oversee virtualization platforms (VMware, Hyper-V): provisioning, resource management, replication, and disaster recovery.
- Administer file shares, permissions, drive mappings, and data access controls.
- Implement and maintain network segmentation, VLANs, QoS, and IP address management to optimize client network performance.
- Administer cloud services including Microsoft 365, Azure AD, Exchange Online, SharePoint, Teams, and Intune.
- Implement and monitor backup and disaster recovery solutions (Datto, Veeam), ensuring data integrity and recovery readiness.
- Troubleshoot complex network connectivity issues, packet loss, or latency using diagnostic tools (ping, traceroute, Wireshark).
Advanced Troubleshooting & Escalation
- Act as the final escalation point for complex incidents involving cross-platform dependencies or critical infrastructure failures.
- Perform advanced diagnostics across server, storage, network, and cloud layers — including performance bottlenecks, hardware issues, and network latency/root cause analysis using tools like Wireshark, Event Viewer, and Performance Monitor.
- Develop and execute remediation plans that minimize downtime and ensure sustainable resolution.
- Partner with Tier I and II teams to guide escalations, improve diagnostic skills, and enhance technical maturity.
Operational Excellence & Project Collaboration
- Collaborate with vCIOs and Project Engineers on infrastructure initiatives such as migrations, upgrades, and security hardening.
- Maintain detailed technical documentation and contribute to standardized best practices and knowledge base content.
- Proactively monitor and maintain systems using ConnectWise Manage & Automate, ensuring reliable performance, patch compliance, and security posture.
- Identify opportunities for process improvement, automation, and modernization within client environments.
Required Skills & Experience
- 5+ years of progressive IT experience, with at least 2+ years in a senior or escalation role within an MSP or multi-client environment.
- Expert-level knowledge of:
- Windows Server (2016–2022), Active Directory, Group Policy, DNS/DHCP
