Orbis Ops
Mc Lean, VA Full Time
POSTED ON 6/20/2026
AVAILABLE BEFORE 8/19/2026

Orbis is looking for a Senior Microsoft 365 Administrator who has grown up in the Microsoft ecosystem, uses Claude as a core part of how they work, and shows up every day with a servant mindset and an instinct to find yes. This is a hands-on, people-facing role at the center of how Orbis operates. Every employee will know your name and be glad they do.

Duties/Responsibilities

  • Microsoft 365 & Identity
    • Own the M365 tenant end to end — users, groups, licenses, Exchange Online, Teams, SharePoint, OneDrive, and Defender
    • Manage the full Entra ID identity lifecycle — provisioning, offboarding, MFA, Conditional Access, SSO, and SCIM
    • Maintain and enforce security and compliance policies across the M365 environment
  • Endpoint & Device Management
    • Procure, enroll, configure, and manage the end device fleet across Mac and Windows
    • Enforce device compliance policies via Intune and Jamf Pro
    • Manage Apple Business Manager and Windows Autopilot enrollment workflows
    • Own asset tracking, warranty management, and device refresh cycles
  • Employee Experience
    • Serve as the first and last point of contact for employee technology issues — you own it until it’s closed
    • Deliver a best-in-class new hire technology experience on day one
    • Own IT onboarding and offboarding end to end — from pre-day-one provisioning and equipment readiness through full access revocation, device retrieval, and account deactivation at separation
    • Use Claude daily to accelerate documentation, troubleshooting, scripting, and communication
    • Maintain documentation that is useful

Required Skills/Abilities

  • 6 years of deep, hands-on Microsoft 365 and Entra ID administration — this is your world
  • Microsoft 365 Certified: Administrator Expert (MS-102) — earned because you wanted to, not because HR asked
  • Expert-level knowledge of Exchange Online, Teams, SharePoint, and OneDrive
  • Strong Entra ID depth — Conditional Access, identity governance, SSO federation, SCIM provisioning
  • Intune endpoint management including compliance policies, app deployment, and configuration profiles
  • Jamf Pro experience for Mac fleet management
  • Apple Business Manager and Windows Autopilot fluency
  • Active Claude user — you use it to move faster, write better, and solve harder problems

Desired Skills/Abilities

  • AZ-104 or SC-300 certification
  • Experience in a defense or national security environment
  • Familiarity with Cyber Essentials Plus or CMMC 2.0 compliance frameworks
  • PowerShell scripting comfort

Character

  • You are hungry — you pursue mastery because standing still feels wrong
  • You are a servant leader — titles don’t impress you, impact does
  • You get to yes — your default is to find a way, not explain why something won’t work
  • Warm, patient, and genuinely enjoys making people’s day easier

Physical Requirements

  • Sedentary Work: Primarily performs work in a seated position for extended periods of time; occasionally required to stand, walk, or move about the work area
  • Fine Motor Skills: Regularly required to use hands and fingers to operate a computer keyboard, mouse, and other standard office equipment
