IT Help Desk (Tier 1)

Hanwha Defense USA IncArlington, VA
Onsite

About The Position

HDUSA is looking for a Junior Helpdesk Technician to join our IT team at our corporate office. This is an entry-level, onsite position perfect for someone early in their IT career who wants to learn, grow, and build a strong foundation in technology support. You’ll be the first point of contact for employees who need help — resolving Tier 1 tickets, jumping in on hands-on tasks around the office, and keeping our day-to-day technology running smoothly. We’re not looking for someone who already knows everything. We’re looking for someone sharp, curious, and dependable that we can mentor and grow with us as the company grows. Technology at HDUSA is moving fast, and AI is a real part of how we work and where we’re headed. We want someone who is genuinely excited about AI and emerging technology — curious about how these tools work, eager to experiment with them, and interested in helping the organization put them to good use. You don’t need prior AI experience; you need the enthusiasm and willingness to dive in and learn.

Requirements

  • A recent graduate (or equivalent) ready to start a career in IT
  • Strong interest in technology and a genuine curiosity about AI and emerging tools
  • A helpful, customer-service mindset and clear communication skills, both verbal and written
  • Eagerness to learn, take feedback, and grow into bigger responsibilities
  • Reliability, attention to detail, and a willingness to roll up your sleeves onsite
  • Comfort with everyday computing (Windows, common business apps, basic troubleshooting)
  • U.S. Citizenship is required
  • Must be able to pass a background check and meet eligibility requirements to work in a controlled/regulated (CMMC/CUI) environment
  • Must be authorized to work in the United States without sponsorship

Nice To Haves

  • CompTIA A+, Security+, or similar certifications
  • Working toward (or open to pursuing) CompTIA Security+ — we’ll support certification as you grow, as it’s a common baseline in our industry
  • Internship, part-time, or hands-on experience supporting users or hardware
  • Familiarity with ticketing systems, Microsoft 365, Intune, or basic networking concepts (TCP/IP, DNS, DHCP)
  • Any personal projects, tinkering, or exposure to AI tools

Responsibilities

  • Respond to and resolve Tier 1 helpdesk tickets within established service-level expectations (SLAs), in a timely and professional manner
  • Provide onsite support for hardware, software, peripherals, and connectivity issues
  • Set up, image, enroll, and deploy laptops, desktops, mobile devices, and other end-user equipment
  • Support Windows 11, Microsoft 365 (Outlook, Teams, OneDrive), and common business applications
  • Assist employees with account access, password resets, and common application questions
  • Provide basic support for mobile devices (iPhone/iPad) and endpoint management enrollment
  • Support conference rooms, AV equipment, and onsite events
  • Document issues, resolutions, and procedures in our ticketing/knowledge system
  • Escalate complex problems to senior IT staff and learn from how they’re solved
  • Help with general IT tasks and projects as the team needs

Benefits

  • We’ll support relevant certifications (such as CompTIA Security+) as you develop.
