About the role

What you’ll do

• Design and deploy a scalable, zero-trust IT and security foundation that supports a high-performance, engineering-driven organization

• Implement and manage a unified identity and access platform, including SSO, role-based access controls, and MFA across SaaS tools and cloud environments

• Own the full lifecycle of our internal technology stack, including tool selection, onboarding, access management, automation of offboarding, and cost optimization

• Establish baseline IT and security policies, documentation, and controls appropriate for a fast-growing startup

• Build and operate incident response processes, including logging, alerting, and clear playbooks for handling security events

• Identify gaps, manual processes, or security risks and proactively fix them without needing direction

What you'll bring

• You are deeply hands-on and comfortable owning systems end-to-end, not just coordinating vendors

• You have strong experience with modern IT tooling such as MDM (Jamf or Kandji), cloud infrastructure (AWS), and identity providers (Okta, Google, or similar)

• You understand that for a fast-moving AI company, security must be automated, integrated into workflows, and designed to scale

• You thrive in ambiguous environments and are energized by building something from scratch
  You have ideally been the first or early IT or Security hire at a high-growth startup

• You can translate complex technical and security requirements into clear, actionable guidance for the rest of the company

Benefits include

• Medical, dental, and vision insurance

• Daily lunch, snacks, and beverages

• Flexible time off
