About the role

Key responsibilities & impact

Administer and monitor Windows servers, Active Directory, DNS, DHCP, Group Policy, and user accounts across corporate and multi-state Regional Office environments
Maintain network infrastructure including switches, routers, wireless access points, and VPN connections for reliable, secure connectivity
Monitor system performance, backups, and logs to resolve issues before they cause outages
Plan and perform system updates, patches, and software deployments, coordinating across sites and time zones
Manage user access provisioning and de-provisioning, including timely removal of access for departing employees
Administer Microsoft 365 services including Exchange Online, SharePoint, Teams, and OneDrive
Verify backup completion and perform periodic test restores to ensure data recovery capability
Support corporate applications including FAS, Traverse, HubSpot, legacy systems, and the Jani-King mobile application
Design, implement, and maintain security controls including MFA, least-privilege access models, account policies, and endpoint protection across all sites
Monitor and triage security alerts from antivirus, firewall, and email security systems, investigating suspicious activity and responding to threats
Lead response to security incidents — isolating affected systems, resetting credentials, performing root-cause analysis, and escalating as appropriate
Own vulnerability management: apply security patches promptly, disable unused services, and follow hardening guidelines
Develop, test, and document security baselines and configuration standards, keeping systems consistent across all states
Support security awareness efforts, communicating threats such as phishing, ransomware, and social engineering to staff
Ensure compliance with Jani-King’s information security policies, including acceptable use, data classification, and approved-systems standards
Identify repetitive, manual, or error-prone IT processes and engineer automated solutions, treating automation as core to the role
Evaluate each candidate process on clear factors — frequency, time cost, error rate, risk, stability, and maintainability — and articulate why a task should or should not be automated
Recognize and document the limits of automation, flagging poor candidates with the reasoning recorded
Design, write, test, and maintain automation using PowerShell, batch, Python, or similar tools for provisioning, reporting, patch deployment, monitoring, and routine maintenance
Build automation that is observable and safe — with logging, error handling, alerting, and rollback considerations — so processes fail loudly rather than silently
Lead and support digital transformation initiatives such as modernizing legacy workflows and standardizing tooling across sites
Maintain clear documentation for all automation and scripts so they can be understood, audited, and maintained by others
Serve as senior technical escalation point for complex hardware, software, network, and application issues from corporate staff and Regional Offices
Provide remote support to multi-state Regional Offices using Remote Desktop, VNC, or similar tools
Document issues, troubleshooting steps, and resolutions in the IT ticketing system (Jira), building a searchable knowledge base
Address the root cause of recurring issues through automation, configuration changes, or user training to reduce repeat tickets
Deploy, configure, and troubleshoot workstations, laptops, printers, and mobile devices; maintain IT asset inventory and coordinate hardware procurement
Perform basic server hardware maintenance and coordinate warranty support with vendors
Lead and support IT projects including system migrations, software rollouts, infrastructure upgrades, and new application implementations across multiple states
Create and maintain IT documentation including system configurations, network diagrams, SOPs, and troubleshooting guides
Continuously evaluate IT processes for opportunities to automate, consolidate, or eliminate work, proposing improvements with a clear cost/benefit rationale
Coordinate with external IT vendors and service providers for equipment repairs, software support, and infrastructure services.
