Helpdesk Technician (Tier 1)

Location: Rosslyn, VA (Onsite)

About the Role

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.

We’re an AI-Forward Team

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.

What You’ll Do

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

What We’re Looking For

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)

Eligibility Requirements

Due to the nature of HDUSA’s work and our regulatory environment, 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 Have (Not Required)

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

Physical & Onsite Requirements

This is a fully onsite role at our Arlington, VA office
Ability to lift and move equipment up to 25 lbs with or without assistance
Ability to sit, stand, stoop, crouch, and perform repetitive-motion activities (keyboard, phone) for extended periods
Ability to move between offices, conference rooms, and equipment areas throughout the day

Why Join Us

This is a ground-floor opportunity to learn the ropes of enterprise IT in a supportive, hands-on environment. You’ll work directly alongside experienced engineers, get real mentorship, and have room to grow your skills and your career as HDUSA grows. We’ll support relevant certifications (such as CompTIA Security+) as you develop. If you’re green but driven, this is a place to be molded into a strong IT professional.

We are an equal opportunity employer. All qualified applicants will receive consideration without regard to race, color, religion, national origin, age, sex, gender identity or expression, sexual orientation, disability, veteran status, or any other protected characteristic.
