    • Support implementation and rollout of new features and tools.
  • Help Desk & Ticketing
    • Handle L1/L2 support tickets across hardware, software, accounts, and connectivity issues.
    • Meet defined SLAs for response and resolution.
    • Document solutions and contribute to a self‑service knowledge base.
  • Office IT & Infrastructure Support
    • Support office IT (Wi‑Fi, printers, conference rooms, network connections).
    • Assist with office moves, expansions, and new equipment deployments.
  • Documentation & Process
    • Maintain accurate asset records and lifecycle updates.
    • Follow and improve IT runbooks, SOPs, and checklists.
    • Provide feedback to improve processes, tooling, and user experience.

    • Hands‑on experience managing Windows and macOS endpoints.
    • Experience administering Microsoft 365 in a business environment.
  • Technical Skills
    • Familiarity with device management tools (Intune / Endpoint Manager or similar).
    • Working knowledge of networking basics (IP, DNS, DHCP, Wi‑Fi).
    • Ability to troubleshoot hardware, OS, and application issues efficiently.
  • Soft Skills
    • Strong customer‑service mindset; patient and clear with non‑technical users.
    • Organized, reliable, and able to manage multiple tickets and tasks.
    • Good written communication skills for documentation and user‑facing articles.
  • Nice to Have
    • Experience in a high‑growth or multi‑site environment.
    • Exposure to security best practices, MFA, and SSO.
    • Experience in manufacturing, energy, or hardware–software environments.
