Security Engineer, Corporate Security

Notion Notion · Enterprise · San Francisco, CA · Security

This role focuses on building and automating technical controls for corporate security, specifically for identity, endpoints, and SaaS applications, with a significant emphasis on securing AI tool usage for employees. The engineer will harden IAM, manage endpoint security, secure AI tool usage, reduce SaaS risk, and automate security processes using Python and Terraform. The role requires experience in corporate security engineering at a cloud-native company and knowledge of identity providers, endpoint tooling, and cloud platforms.

What you'd actually do

  1. Harden our identity and access management stack, including Okta and Google Workspace, with phishing-resistant MFA, strong SSO and SCIM lifecycles, and least-privilege access across SaaS.
  2. Run our endpoint security program across a macOS-first fleet, including MDM, EDR, and configuration baselines, with working coverage for Windows and ChromeOS.
  3. Secure AI tool usage at the endpoint, including governance of large language models, AI agents, and model context protocol (MCP) integrations; detect and prevent unauthorized or risky AI service access and data exfiltration through AI-enabled tools.
  4. Reduce SaaS risk at scale through SSPM tooling and custom automation, including detection of risky OAuth grants, excessive permissions, shadow IT, and configuration drift.
  5. Write code (Python, Terraform) to automate access reviews, onboarding and offboarding, configuration drift detection, and audit evidence collection.
