  • Requires hands-on administration of an IDaaS/MDM platform such as Rippling, JumpCloud, Okta, Azure AD/Entra, Jamf, or Intune, including SSO, MFA, and device policy management.
  • Requires experience supporting macOS and Windows endpoints, including patching and device compliance.
  • Requires Google Workspace administration across user lifecycle, groups, and shared drives.
  • Requires experience working a ticket queue in Jira or a similar ITSM tool and meeting response SLAs.
  • Requires working scripting ability in at least one language such as Python, Bash, or PowerShell, with interest in automating repetitive work.
  • Requires clear written communication to document work so others can repeat it.
  • Requires sound judgment about when to resolve, escalate, or request security review.
  • Requires U.S. citizenship.
  • Requires at least one certification aligned to the DoD Cyber Workforce Framework (DoDM 8140.03), or the ability to earn one within 6 months of hire; examples include CompTIA A+, Network+, Security+, ISC2 SSCP, or Microsoft, Google Workspace, or Jamf administrator certifications.

Responsibilities

  • Run onboarding and offboarding end-to-end, including account provisioning, hardware setup, role changes, same-day deprovisioning, and device wipe and recovery, including no-notice terminations.
  • Work the IT service desk queue in Jira Service Management, handling password and MFA resets, access requests, department and admin requests, and troubleshooting within defined SLAs.
  • Write and maintain SOPs, runbooks, and knowledge-base articles so common requests can be self-served or handled consistently.
  • Escalate security-relevant issues, such as suspected phishing, data spills, or anomalous access, to the cyber team using established procedures.
  • Administer macOS and Windows endpoints in Rippling MDM, including enrollment, configuration profiles, and policy enforcement; help finish migrating remaining devices off JumpCloud.
  • Enforce OS and application patching, and report on device compliance across the fleet.
  • Deploy and maintain endpoint security agents (EDR) and DLP controls, such as restricting unmanaged cloud storage.
  • Track hardware inventory, assignment, and retirement.
  • Administer Google Workspace users, groups, organizational units, shared drives, and email authentication; support the Google Drive migration.
  • Administer Atlassian, GitHub organization access, Slack, and other core SaaS platforms.
  • Maintain SSO and MFA integrations between the identity provider and downstream applications.
  • Maintain the tool and license inventory; track renewals and expirations, reclaim inactive licenses after 90+ days, and flag shadow IT found through the SaaS management platform.
  • Run monthly user access reviews for Google, GitHub, AWS, and other systems, and keep the evidence audit-ready.
  • Apply least-privilege access and admin-access guardrails consistently across environments.
  • Support CMMC Level 2 and NIST 800-171 compliance through evidence collection and accurate documentation of IT controls.
  • Script repetitive tasks, such as onboarding checklists, access-review exports, license-expiry alerts, and ticket routing.
  • Partner with cyber and infrastructure engineers on IT automation and tooling-as-code initiatives as the role matures.

Desired Qualifications

  • Experience in a CMMC, ITAR, FedRAMP, or other regulated environment; candidates from adjacent regulated industries are encouraged to apply.
  • Administration of Atlassian, GitHub organizations, or Slack Enterprise.
  • Familiarity with SaaS management or IT asset management platforms.
  • Exposure to AWS IAM, EDR tooling such as CrowdStrike, or vulnerability scanners such as Nessus.
  • Experience building automations or workflows that remove manual steps from an IT process.
  • Familiarity with NIST 800-171 or NIST 800-53 controls and audit evidence collection.

About the Company

Istari Digital

Model-based engineering platform and digital twins

Istari Digital is building a platform to create an engineering metaverse for design, testing, and certification of physical systems entirely through modeling and simulation. It uses digital twins and digital threads to connect a system’s lifecycle in a single, shared, model-based environment, allowing virtual validation before any physical build. Its differentiators include leadership with deep government and defense experience, notable Air Force contracts, and a focus on digital-certification workflows that combine software-like agility with hardware development. The goal is to speed up hardware development, reduce cost and environmental impact, and enable verifiable, virtual airworthiness certification for complex assets.
