IT System Administrator (Fuse Corp) at Fuse (San Leandro, CA)IT System Administrator (Fuse Corp)

We are building one of the most potentially consequential companies of the century. Our mission is to accelerate the world's transition to fusion energy while safeguarding humankind. This is not a normal company. This is not a normal job. We are committed for the long term to win.

You'll own the day-to-day technology experience for every employee, from the laptop that shows up on someone's first day to the SaaS tools they use every hour. You'll work closely with our Security Engineer, who sets policy and standards; you'll be the one who implements, enforces, and supports them day to day. This is a hands-on, high-visibility role at a company small enough that your work is immediately felt by everyone, and structured enough that you're not building processes from zero.

• Obsess about the details — sloppy work costs us later, so do it right the first time.
• Care — pick up the trash. Do things no one asks you to do. Go the extra mile because you care.
• Act with urgency — every hour matters more than it feels like it does.
• Be responsible for the outcome, not just the task; if it is not working, it remains your problem until it is fixed.
• Assume good intent — disagree openly, then commit fully once a call is made.

Core Responsibilities

• Provision and deprovision accounts across IdP and various SaaS platforms for onboarding/offboarding.
• Configure and ship laptops/desktops to new hires; run new-hire IT orientation.
• Administer macOS and Windows MDM providers → enrollment, patching, compliance policies, app deployment.
• Administer IdP (SSO, groups, app assignments), collaboration platforms, licensing, etc.
• Serve as primary point of contact for day-to-day IT issues; triage and resolve tier 1/2 helpdesk requests, escalating as needed.
• Maintain and troubleshoot network gear (Wi-Fi, switches, basic firewall/VLAN configuration).
• Implement and enforce endpoint compliance and access policies defined jointly with the Security Engineer (e.g., MDM baselines, conditional access, MFA enrollment).
• Maintain IT documentation, SOPs, and asset inventory.
• Manage hardware/software procurement, license renewals, and vendor relationships for the IT toolset.

• 2+ years in an IT Administrator, IT Support, or Systems Administrator role.
• Hands-on experience with an MDM tool (Kandji, Intune, Jamf, or similar).
• Working knowledge of an SSO/IdP platform (Okta or similar) — user/group management, app integrations, basic policy configuration.
• Experience administering Google Workspace and/or Microsoft Entra ID.
• Comfortable supporting both macOS and Windows environments.
• Basic networking knowledge — VLANs, Wi-Fi troubleshooting, DHCP/DNS fundamentals.
• Strong written and verbal communication skills for supporting non-technical employees.

• Experience standing up or scaling IT processes at a company growing from ~50 to ~150+ employees.
• Direct experience with Ubiquiti/UniFi network equipment.
• Exposure to security fundamentals (MFA, conditional access, endpoint compliance) with interest in growing into security-adjacent work.
• Scripting ability (Python, Bash, or PowerShell) to automate provisioning, deprovisioning, or reporting.
• Experience supporting engineering-heavy environments (e.g., CAD workstations, lab or hardware equipment) alongside standard corporate IT.
• Experience building internal documentation that's actually used, not just written once and abandoned.

Additional Requirements

• Availability to provide occasional support outside standard business hours for urgent issues (e.g., account lockouts, outages).
