ABOUT THE ROLE

We’re looking for a hands-on IT Helpdesk engineer to be our go-to person in the Kyiv office. You’ll handle day-to-day hardware and software support for colleagues, manage equipment, and work closely with the Corp-IT team spread across Warsaw, Tel Aviv, and Limassol. This is a great opportunity to grow into a full sysadmin role - you’ll get exposure to modern cloud-based infrastructure and enterprise tooling from day one.

WHAT YOU'LL DO

• Be the first point of contact for IT issues in the Kyiv office (hardware, software, connectivity, accounts)
• Set up and configure laptops (macOS and Windows) for new hires, including enrollment in MDM
• Handle onboarding and offboarding tasks: account provisioning, equipment hand-off, asset tracking
• Troubleshoot network and Wi-Fi issues in the office; escalate to senior engineers when needed
• Manage and track IT inventory (laptops, peripherals, accessories)
• Process IT requests via our helpdesk system (Jira Service Management)
• Purchase the IT equipment 
• Follow and improve documentation for common support procedures in Confluence

WHAT WE'RE LOOKING FOR

• Basic understanding of networking: IP addressing, DHCP, DNS, Wi-Fi troubleshooting
• Comfortable working with both macOS and Windows in a corporate environment
• Familiarity with Google Workspace (Gmail, Drive, Meet, Admin basics)
• Understanding of user account lifecycle: creation, access management, password resets
• Ability to follow runbooks and document your own steps clearly
• Good communication skills - able to explain technical issues to non-technical colleagues
• Responsible and reliable: office presence is critical, this role cannot be done remotely
• Intermediate English: enough to read technical documentation and communicate in writing with the global team

NICE TO HAVE 

Any of the following is a bonus, not a dealbreaker:

  Okta / SSO basics     

  Jamf or Intune experience     

  CLI / basic scripting     

  FortiNet / VPN awareness     

  Previous helpdesk role     

  IT course or certification     

WHAT WE OFFER

• A real learning environment with hands-on mentorship from experienced engineers
• Gradual exposure to modern enterprise tools: Okta, Jamf, Intune, GCP, CrowdStrike, Cloudflare
• A collaborative, distributed Corp-IT team across four countries
• A clear path to grow into a full sysadmin role over time
