About The Role
Nscale is hiring a Staff Engineer, Security Assurance & Audit to lead a high-rigor, audit-ready assurance function across Nscale's global AI infrastructure.
This is a hands-on senior individual contributor role with significant scope. You will own the operating model that allows Nscale to meet customer commitments, expand certification scope, maintain audit readiness, and produce defensible evidence for external auditors and enterprise customers.
As Nscale scales global AI infrastructure, we need a technical assurance leader who can turn customer commitments, certification requirements, and control obligations into durable programs, clear ownership, strong evidence, and repeatable execution.
This role sits at the intersection of security, audit, compliance, infrastructure, physical security, engineering, customer trust, and legal. You will partner directly with control owners across the company to ensure controls are scoped, implemented, evidenced, tested, and defensible.
What You'll be Doing
Assurance Program Leadership
- Own security assurance execution across SOC 2 Type II, the ISO family of standards, and other applicable frameworks.
- Lead certification and audit-readiness planning for new sites, systems, services, and customer commitments.
- Build and maintain an integrated audit calendar across certification bodies, readiness assessments, customer deadlines, surveillance audits, and scope expansions.
- Drive cross-functional readiness for audit fieldwork, evidence submission, auditor walkthroughs, and control-owner interviews.
Scope Expansion and Site Readiness
- Lead assurance planning for new launches and site-scope expansions.
- Translate site launch commitments into control requirements, evidence requirements, readiness trackers, and audit-response packs.
- Partner with Physical & Data Center Security, Enterprise Security, Infrastructure, Legal, and Customer Trust to define boundaries, control ownership, and evidence expectations.
- Support customer-specific readiness efforts.
