Job description

Overview
We are seeking a curious, hands-on, and motivated Junior Systems Administrator to join our fast-paced MSP team. This is not your average entry-level role—you’ll gain real-world experience across diverse IT environments, from scripting and automation to infrastructure and cloud services. Whether you’re self-taught or just getting started in your IT career, this is an opportunity to fast-track your skills and contribute directly to impactful tech solutions.

  • Support and administer Microsoft 365 tools like Exchange Online, SharePoint, and Teams
  • Manage users, devices, and licenses in Microsoft Entra ID (Azure AD)
  • Write or learn to write PowerShell scripts to automate routine tasks
  • Troubleshoot networking issues (DNS, DHCP, VPNs, firewall rules)
  • Maintain and support Windows Server and Linux systems
  • Assist in monitoring and alerting using tools like NinjaOne, Site24x7, and Datadog
  • Work within cloud environments including AWS and Azure (resource provisioning, IAM, backups)
  • Help deploy backup and disaster recovery solutions
  • Support endpoint protection platforms like SentinelOne and Huntress
  • Participate in onboarding projects and infrastructure setups for new clients
  • Build API integrations and automation workflows
  • Support VoIP systems including Teams Phone, Zoom Phone, and 3CX

Skills

  • 0–5 years of hands-on experience (helpdesk, sysadmin, homelab all count)

  • Basic understanding of IT networking (TCP/IP, DNS, DHCP, VPN)
  • Familiarity with Microsoft 365 and PowerShell (or willingness to learn)
  • Clear communication skills and the ability to collaborate and ask questions
  • Exposure to cloud infrastructure (AWS, Azure) is a plus
  • Understanding of endpoint security, scripting, and documentation best practice

This is more than a job—it’s your launchpad. Our Junior Systems Administrators gain more experience in one year than many do in five. You’ll work across environments, contribute to meaningful projects, and be mentored by experienced engineers who want to see you grow.
