## Job Description

## Role Scope

- Build guardrails as code: policies, scanning, and paved roads that make the secure path the fast path for engineers.
- Engineer detection and response across cloud infrastructure, from API abuse to compromised credentials to tenant escape.
- Secure the multi-tenant boundary where customer workloads, some of the most targeted in AI, share infrastructure.

## Requirements
- Secured production cloud or bare-metal infrastructure hands-on, not just audited it.
- Shipped security tooling engineers actually adopted.
- Found and fixed real isolation or privilege-escalation issues.
- Write production-quality code and treat policies as software.
- Run incident response on infrastructure you helped build.

## Nice-to-Haves
