What are the responsibilities and job description for the Lead IT Administrator position at Block MB?
A high-growth AI company backed by companies like Google Ventures is looking for an IT Administrator to own its entire IT function as it scales from around 120 to 500 employees.
This isn't a ticket-queue role. You'll build and own the systems that power the company's identity, endpoints, SaaS stack, and corporate security, reporting directly to the Head of Engineering/CTO with real decision-making authority.
What you'll own:
- Identity and access: Google Workspace, Okta, SSO/SCIM, and all SaaS applications
- Mac-first endpoint environment: MDM (Jamf or Kandji), security baselines, patching, and device compliance
- Automated onboarding/offboarding: provision new employees in minutes, not hours
- Corporate security: endpoint security, ZTNA, SOC 2/ISO 27001 audit readiness
- SaaS stack management: provisioning, licensing, and vendor lifecycle
- AI-powered automation: use AI tools to eliminate repetitive IT work and scale operations without adding headcount
- Day-to-day IT operations: identity, devices, networking, and office infrastructure
What we're looking for:
- 5-15 years in IT administration (sweet spot: 7-10 years)
- Owned end-to-end IT at a high-growth startup (50-300 employees)
- Comfortable in a fast-paced, in-person engineering environment
- Hands-on experience with IdP (Okta or equivalent): SSO, SCIM, and lifecycle management
- MDM deployment and management (Jamf or Kandji)
- Built automated provisioning workflows, not just maintained them
- Endpoint security, ZTNA, and compliance experience (SOC 2/ISO 27001)
- Actively uses AI to automate IT workflows
- Bonus: technical degree (CS, physics, math); experience at a Series A-D startup in the last 3 years
Why join:
- Ground-floor ownership at a $1B AI company with serious momentum
- Meaningful equity designed to be worth more than base salary over 2-3 years
- AI-first culture: you're building scalable systems, not chasing fires
- Direct access to leadership with no layers of bureaucracy
- Premium health, unlimited PTO, daily meal stipends, 401(k), parental leave, $300 desk setup
- Collaborative in-person NYC office
On-site, 5 days/week in New York City
