On-Site IT Support Technician

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.

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, One Drive, 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.
