About the role

AI is the fastest-moving attack surface in the enterprise.
Copilot, ChatGPT Enterprise, Gemini, Claude, and a wave of agentic tools are being wired into corporate SaaS faster than security teams can keep up - with broad OAuth scopes, opaque data flows, and non-human identities acting on behalf of employees.
Obsidian sits directly in the path of this shift.

Develop deep expertise in how AI platforms (ChatGPT Enterprise, Copilot, Gemini, Claude, Glean, agentic frameworks) authenticate, what scopes they request, and where risk concentrates.
Build threat models covering identity, data access, non-human identities, and integration risk.
Build and improve data pipelines for high efficiency, development velocity, and low cost.

3+ years in security engineering as a builder, with clear ownership of shipped work.
Hands-on experience with a modern data stack (DBT and a columnar warehouse or query engine such as ClickHouse, Snowflake, BigQuery, or Databricks).

Strong grasp of how SaaS platforms (Google Workspace, Microsoft 365, Salesforce, Okta) expose data - APIs, event schemas, permissions, auth flows.
Deep knowledge of AI and SaaS security - OWASP LLM Top 10, MITRE ATLAS, prompt injection, agent/tool-use risks, OAuth abuse, and identity models across major AI and SaaS platforms.
