System Administrator (Internal IT)

We are looking for a System Administrator to own the administration and integration of the platforms that run Resultant. This is a hands-on, senior-individual-contributor role on our Internal IT team. You will be the go-to administrator for our Microsoft 365 and Azure tenant, the owner of email flow and messaging security, and the system administrator for our business platforms, including ConnectWise, HubSpot, ADP, and NetSuite, and the integrations that tie them together.

You will sit at the intersection of Accounting, Finance, Talent, Sales, and our critical Managed Services and Professional Services business. Much of the work is making systems behave the way the business needs them to: translating a request into the right configuration, understanding the downstream impact (financial reporting, access risk, compliance), and documenting it so the next person can support it. We are a lean team, so we want someone who automates first, documents as they go, and is comfortable owning an outcome end to end.

Consider your day-to-day responsibilities in this role:

Microsoft 365 & Entra ID Administration

• Administer the Microsoft 365 tenant: Entra ID users, groups, roles, administrative units, and E3/E5 licensing.

• Own the identity lifecycle, automating onboarding, role changes, and offboarding from HR events.

• Partner with Security on Conditional Access, MFA, Privileged Identity Management, and least-privilege roles.

• Manage SharePoint Online, OneDrive, and Teams, including provisioning, external sharing, and governance.

• Support our MDM compliance and configuration policies with heavy emphasis on Intune and a smaller subset of Macbooks using Mosyle.

• Automate recurring tasks and reporting

Exchange Online & Email Security

• Own end-to-end mail flow: transport rules, connectors, domains, mailboxes, and groups.

• Maintain SPF, DKIM, DMARC, and MX records, and safely retire legacy and acquired domains.

• Administer Defender for Office 365 and Exchange Online Protection policies.

• Serve as the escalation point for delivery issues using message trace, header analysis, and NDR diagnosis.

• Manage email signatures, disclaimers, and banners across departments and brands.

• Support Legal with retention, eDiscovery, and litigation holds in Microsoft Purview.

Azure Administration

• Administer Azure subscriptions, resource groups, RBAC, and cost visibility.

• Manage enterprise apps and app registrations, including SSO (SAML/OIDC), SCIM provisioning, secret rotation, and consent governance.
