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.
• Control Framework and Evidence Quality
• Partner with compliance engineering and control‑mapping owners to maintain a unified control framework across SOC 2, ISO, NIST, and customer‑specific obligations.
• Define evidence standards for control design, operating effectiveness, sampling, retention, traceability, and audit defensibility.
• Review evidence for sufficiency, accuracy, timeliness, and relevance before submission to auditors or customers.
• Identify evidence gaps, control weaknesses, and repeat failure patterns.
• Ensure audit findings are routed into remediation workflows with accountable owners and due dates.
• External Audit and Customer Audit Support
• Manage external auditor engagement, including request lists, evidence submissions, control narratives, walkthrough preparation, and issue follow‑up.
• Serve as a primary assurance representative during external audits and customer security reviews.
• Translate technical controls into clear, defensible audit narratives.
• Partner with Customer Trust to prepare audit‑backed responses to customer security reviews and enterprise customer assurance requests.
• Automation and Continuous Readiness
• Partner with GRC Engineering to automate evidence collection, control monitoring, and audit‑readiness reporting.
• Support the implementation and operationalization of a modern GRC platform, including evidence integrations and automated workflows.
• Help define continuous control monitoring requirements and control health indicators.
• Use automation and AI‑assisted workflows where they improve evidence quality, audit preparation, control validation, or remediation tracking.
• Reduce manual audit preparation by building repeatable workflows, templates, and source‑of‑truth systems.
• KPIs
• Audit‑readiness status across in‑scope certifications and sites
• Evidence completeness, quality, and traceability
• On‑time completion of audit requests and readiness milestones
• Control ownership and evidence maintenance coverage across in‑scope frameworks
