Job description

We're looking for a Junior Network Administrator to be the first IT team member based in Europe, supporting our growing teams across the UK and Ireland. This is a highly visible, frontline role where you'll work closely with employees day-to-day while collaborating with our established US-based IT team.

This is an excellent opportunity for someone early in their IT career who combines strong technical fundamentals with a customer-first mindset and is eager to grow in a collaborative, international environment.

What you'll be doing

  • Act as the first point of contact for IT support across the UK and Ireland, delivering a high-quality, responsive user experience
  • Provide Tier 1 support for hardware, software, and network-related issues via Jira Service Management
  • Troubleshoot and resolve issues across desktops, laptops, and mobile devices
  • Set up and onboard new employees, including device imaging, configuration, and deployment
  • Manage user accounts and access in Active Directory and Microsoft 365 (user provisioning, password resets, mailbox setup)
  • Monitor system performance and escalate trends or recurring issues to senior IT team members
  • Maintain clear and accurate IT documentation, including knowledge base articles and asset tracking
  • Support adherence to internal IT security and compliance standards
  • Partner closely with the US IT team to ensure consistent global support coverage

Working arrangements

  • Hybrid role based in our London office (2-3 days per week onsite)
  • Standard working hours aligned to the UK (8:00am - 5:00pm)
  • Opportunity to collaborate with and support colleagues across both the UK/Ireland and US East Coast teams, providing valuable exposure to a global IT environment

Requirements

  • ~1+ year of experience in an IT support, service desk, or helpdesk role in an employee-facing environment

  • Strong foundational IT knowledge (operating systems, basic networking, end-user support)

  • Demonstrated customer service mindset with excellent communication and problem-solving skills

  • Hands-on experience with:

  • Windows 10/11 and Microsoft Office 365

  • Active Directory and Microsoft 365 administration

  • Ticketing systems (preferably Jira or Jira Service Management)

Basic understanding of networking concepts (IP addressing, DNS, DHCP)

Comfortable working independently while collaborating with a distributed, global team

Strong organisational skills and attention to detail

Nice to have:

  • CompTIA A+, Network+, or similar certifications
  • Experience contributing to IT documentation or knowledge bases

Benefits & conditions

  • Gain exposure to a global IT environment and modern SaaS infrastructure

  • Opportunity to grow your technical skills and progress your IT career

  • Supportive, collaborative team culture
