Your day at NTT DATA
Provide senior-level audit program operations and security assurance support for a global security audit program. The role focuses on coordinating and executing on-site/virtual audits, reviewing audit outputs for quality, maintaining audit calendars, tracking corrective actions (CAP) and remediation closure with third‑party partner sites, and producing operational reporting and forecasts in customer-preferred formats. The scope is advisory/assurance and coordination; technical implementation and remediation delivery are out of scope.
Key Responsibilities:
  • Own day-to-day operations of the global supply chain security audit program, ensuring overall quality control and adherence to customer requirements.
  • Maintain and continuously update the audit calendar; coordinate scheduling with internal stakeholders and third‑party partner sites (e.g., contract manufacturers).
  • Plan and execute on-site or virtual audits as required; manage audit logistics, evidence requests, meeting agendas, and pre-audit readiness activities.
  • Assess partner-site network topology and configuration against defined security requirements; document gaps, risks, and recommendations.
  • Produce high-quality audit reports, including findings, severity/risk rationale, and Corrective Action Plans (CAP) where applicable.
  • Review submitted audit results (from internal/partner contributors) for accuracy, completeness, and quality; drive rework where needed.
  • Track remediation actions and open items; coordinate with audit teams and partner-site IT teams to drive timely closure of security gaps and remediation bugs.
  • Upon request, conduct supply-chain related data security risk assessments and provide written reports with mitigation recommendations; may include mock ISMS/ISO 27001 readiness audits.
  • Support planning and coordination for new security implementations (e.g., kick-off coordination, golden image rollouts, authentication updates) by aligning stakeholders, timelines, and required actions.
  • Develop slide decks and support kick-off and executive update presentations for partner sites and program stakeholders.
  • Provide light security operations coordination support (e.g., triage and reassignment of EDR detection tickets to partner sites; follow up on remediation status).
  • Deliver regular operational reporting (weekly/monthly/quarterly and as required) including progress updates, current status, KPIs, insights, and analysis.
  • Prepare operational forecasts (weekly/monthly/quarterly/bi-annual/annual) with assumptions and risk/opportunity assessments, delivered in advance of each reporting period.
  • Serve as a country or site lead point of contact when assigned; manage stakeholder communications and escalation paths effectively.
  • Maintain strict confidentiality of customer and site information; adhere to customer and site IT policies and procedures.
Qualifications and Experience:
  • 6–10+ years of experience in security auditing, security assurance, GRC, or security assessments; experience with third‑party/vendor or supply-chain audits is highly preferred.
  • Demonstrated experience running audit program operations: scheduling, readiness, evidence management, reporting, CAP creation, and remediation tracking to closure.
  • Working knowledge of ISO/IEC 27001 (ISMS) and common security control domains; ability to perform readiness reviews and control mapping.
  • Solid understanding of enterprise networks and security fundamentals to review network topology/configuration and identify control gaps.
  • Strong stakeholder management and communication skills; able to engage with cross-functional internal teams and partner-site IT teams across geographies.
  • Excellent written English skills with proven ability to produce structured audit reports, executive summaries, KPIs, and forecasts.
  • Comfortable working across time zones and managing multiple sites/workstreams; highly organized and detail-oriented.
  • Willingness and ability to travel domestically and internationally as required.
Preferred Certifications (Nice to Have):
  • CISA, CISSP, ISO/IEC 27001 Lead Auditor/Lead Implementer (or equivalent).
  • Additional relevant certifications in risk management, audit, or security frameworks are advantageous.
