Job description

IMPORTANT NOTE FOR DC-AREA APPLICANTS

• Location: 100% On-Site across the Washington, DC metro area (No remote/hybrid option).
• Security Clearance: This role supports non-profit and commercial clients. A security clearance is NOT required, and OITS does NOT hold, sponsor, or maintain active federal clearances. If maintaining an active clearance is a priority, this role will not be a fit.

About the Role

OITS is a managed service provider supporting non-profit and professional organizations based primarily in the DC metro area and across the US. We are hiring an On-Site IT Support Technician to join our team in a role that balances dedicated on-site support at a primary client location with hands-on work across our broader client portfolio.

You will split your time roughly 50/50 between a full-time client placement, where you serve as the primary in-person IT contact, and supporting other OITS clients with on-site visits, remote troubleshooting, and project work. That means you need to be adaptable: comfortable building deep relationships at one site while also context-switching across different environments, tools, and teams.

MacOS is a major part of this role. Our primary client site is nearly two-thirds Mac, and you will be expected to support macOS as a primary platform, not as a secondary afterthought. That includes troubleshooting macOS-specific issues, supporting Microsoft 365 apps on Mac (Outlook, Teams, OneDrive, etc.), managing Macs through MDM, and handling the nuances of a mixed Mac/Windows environment day to day.

This is not a remote position. The right candidate will be someone our clients and our team can count on: someone who shows up every day, on time, ready to help. Reliability, professionalism, and a genuine service mindset matter as much as technical skill.

What You’ll Do

• Serve as the primary in-person IT contact at a dedicated client site, supporting all end users on-site
• Provide on-site and remote support for additional OITS clients as scheduled, including site visits, remote sessions, and project-based work
• Support a Mac-heavy environment: troubleshoot macOS issues, manage Mac hardware lifecycle, and handle macOS updates, profiles, and configurations
• Support Microsoft 365 apps running on macOS (Outlook, Teams, Word, Excel, OneDrive), including Mac-specific quirks around identity, syncing, and app behavior
• Troubleshoot and resolve issues with Windows 11 desktops and laptops across varied client environments
• Support Google Workspace (Gmail, Drive, Calendar, Meet, Admin Console) and Microsoft 365 (Outlook, Teams, SharePoint, OneDrive)
• Manage user accounts and devices, including Entra ID, MDM enrollment (Jamf, Intune, or similar), and provisioning for both Mac and Windows
• Support iOS and Android mobile devices
• Troubleshoot local network issues: Wi-Fi connectivity, printers, switches, and access points
• Support audio/video conferencing hardware and platforms (Google Meet, Zoom, Teams)
• Escalate complex issues to senior OITS consultants with clear documentation
• Maintain accurate ticket records and asset inventory across multiple client environments
• Communicate clearly and professionally with staff at all levels, including non-technical users and executives
• Adapt quickly to different client environments, documentation standards, and toolsets

What We’re Looking For

Must-Have

• 3-5 years of hands-on IT helpdesk or desktop support experience
• Strong macOS support skills: you should be as comfortable troubleshooting a Mac as a Windows PC. This is not a Windows-first role
• Experience supporting Microsoft 365 apps on macOS, including common issues with Outlook, Teams, and OneDrive on Mac
• Comfortable supporting Windows 11 in a mixed environment alongside macOS
• Working knowledge of Google Workspace and/or Microsoft 365 admin consoles
• Solid understanding of networking fundamentals: TCP/IP, DNS, DHCP, Wi-Fi
• Strong interpersonal and communication skills. You will be the face of IT at client sites
• Reliable, punctual, and professional. This role requires consistent in-person presence
• Able to work independently, manage your own queue, and prioritize across multiple clients without hand-holding
• Comfortable context-switching between different client environments, toolsets, and expectations

Nice to Have

• Experience with Mac-focused MDM platforms (Jamf, Kandji, Mosyle) and/or Apple Business Manager
• Familiarity with Intune for Mac management or cross-platform MDM workflows
• Experience with an RMM or PSA tool (NinjaOne, ConnectWise, Kaseya, etc.)
• Windows Autopilot experience
• CompTIA A+, Network+, Google Workspace, or Microsoft certifications
• Apple Certified Support Professional (ACSP) or equivalent Mac support training
• Prior MSP experience, especially supporting multiple clients simultaneously
• Basic scripting or automation experience (Bash, PowerShell, or similar)

What We Offer

• Competitive salary based on experience
• Health, dental, and vision insurance
• 401(k) with employer matching
• Paid time off and holidays
• Exposure to a wide variety of client environments and technologies
• Supportive team of senior consultants you can learn from and escalat

Important: This Is an On-Site Role

RoleWe want to be direct: this position requires you to be physically present at client locations and the OITS office every business day. There is no hybrid or remote option. Your schedule will be split between a primary client site and other OITS client engagements, so flexibility and reliable transportation in the DC metro area are essential. The DC Metro is a practical option for getting between sites; it's how many of our team members, including long-tenured staff, commute and travel between client locations daily.If reliable, consistent in-person attendance across multiple locations would be a challenge for you, this role is likely not the right fit. If you value variety, building strong relationships with the people you support, and growing your skills across diverse environments, you’ll thrive here.
