Our customers are some of the most security-conscious organisations in the world. How we run IT internally is part of what they buy.

The role

You’ll own corporate IT at Model ML end to end. You’ll run a modern, cloud-native stack and make it the best-run IT function a company our size has. Day one you’re hands‑on. Over time you build the team and the systems that let IT scale with a company that’s adding people every month. You’ll sit close to leadership and work with every team: engineers running coding agents all day, a fast‑growing go-to-market team, and an analyst workforce spread across time zones.

What You’ll Own

• Identity and access: Okta, Beyond Identity and Microsoft Entra ID: SSO, MFA, lifecycle management and SCIM provisioning across every app; Joiner, mover and leaver process, fully automated from HiBob, with same-day access on day one and same-hour revocation on exit; Access reviews and least‑privilege policy.
• Endpoints: Procurement, zero-touch enrolment, MDM, patching, encryption, wipe and re-provision; Endpoint security: CrowdStrike Falcon (MDR and exposure management), ThreatLocker allowlisting, and remote management; Tuning security for engineers who run Claude Code, Codex, Docker and heavy local builds without killing their machines.
• Security operations: Email security (Ironscales), secure browser and DLP (Island), password management (Keeper); Network and remote access across offices and remote staff (Cato); Incident response for corporate IT: triage, escalation, post-mortems.
• SaaS and vendors: Admin for Microsoft 365, SharePoint, Slack, Notion, HubSpot, Linear and the rest of the stack; SaaS inventory, licence management and renewals, so we only pay for what we use; Contracts and relationships with every IT vendor.
• Compliance and customer trust: Corporate IT controls and evidence for SOC 2, ISO 27001 and client due diligence; Partner with our security, compliance and sales teams on diligence questionnaires covering device management, access control, backup and business continuity.
• Offices and people: IT setup for new offices, starting with Dubai; Helpdesk with clear SLAs, a self-serve knowledge base, and a support model that works across London, New York and Asia hours; Budget ownership for IT spend, and a hiring plan for the team as we grow.

Your first 90 days

• Days 0 to 30: Learn the environment. Get admin access to every system. Map how IT runs today and identify the biggest gaps
• Days 30 to 60: Close the gaps. Consolidate licences and tenants, document every system and config, and own first-line support
• Days 60 to 90: Run IT end to end. Automate onboarding and offboarding, publish SLAs, and present a 12-month roadmap and budget

What You’ll Bring

• 8+ years in IT, with at least 3 leading corporate IT at a fast-growing tech company, ideally 100 to 500 people
• Deep, hands-on experience. You’ve built identity and provisioning, not just used it
• Experience running Mac, Windows, and mobile MDM and EDR
• You’ve built or scaled a corporate IT function before
• You’ve supported SOC 2 or ISO 27001 compliant organizations
• Comfortable with scripting and automation (Python, Bash, PowerShell, or workflow tools like Okta Workflows)
• Clear communicator who can explain a control to an auditor and a fix to an engineer
• You care about the user experience of IT. Fast, quiet and self-serve beats tickets and queues

Nice to have

• Experience in financial services or selling into banks and funds
• Zero-trust networking and secure browser rollouts
• Multi-country setup, including new entities and offices
• You already use AI tools to automate your own work

Benefits

Competitive salary, equity options, and comprehensive benefits package to be discussed during the hiring process.
