Job Overview

We are seeking a strategic and experienced Information Security GRC (Governance, Risk & Compliance) Manager to lead and mature our enterprise-wide GRC program across information security, data privacy, and telecommunications regulatory compliance. This role owns the design, execution, and continuous improvement of the GRC function — managing a team of specialists, driving risk-informed decision-making, and serving as a trusted advisor to senior leadership and the CISO.

The ideal candidate brings deep expertise in security frameworks, regulatory landscapes, and telecom-specific compliance requirements, combined with the leadership capability to build high-performing teams and influence cross-functional stakeholders at all levels.


Responsibilities & Duties

GRC Program Leadership

  • Own and drive the organization's GRC strategy, roadmap, and operating model across information security, data privacy, and telecommunications compliance.
  • Build, lead, and mentor a team of GRC specialists, setting clear objectives, performance expectations, and development plans.
  • Report program health, risk posture, and compliance status to the CISO and senior leadership on a regular cadence.
  • Define and track GRC program KPIs and OKRs (Key Performance Indicators / Objectives and Key Results), ensuring measurable outcomes and continuous improvement.

Policy & Standards Governance

  • Oversee the lifecycle management of the organization's information security, privacy, and telecom compliance policy framework — including development, review, approval, and enforcement.
  • Ensure policies and standards are aligned with applicable regulatory requirements, industry frameworks (e.g., ISO 27001, NIST CSF), and business objectives.
  • Establish governance processes to ensure consistent communication, acknowledgment, and enforcement of policies across all business units and personnel.

Risk Management

  • Lead the enterprise information security risk management program, including periodic risk assessments, risk register maintenance, and risk treatment planning.
  • Provide risk-based guidance to business and technology stakeholders, translating complex risk findings into clear, actionable recommendations for executive and operational audiences.
  • Develop and maintain risk appetite and tolerance statements in alignment with organizational strategy, with particular attention to telecom-specific threat vectors (e.g., SS7/Diameter signaling, SIP/VoIP, BGP/DNS, mobile core).
  • Oversee third-party and vendor risk management processes, ensuring supply chain risks are identified, assessed, and mitigated.

Compliance & Audit Management

  • Manage the organization's compliance posture across applicable standards and regulations, including ISO 27001, GDPR, telecom-specific regulations, and other relevant frameworks.
  • Direct and coordinate internal and external audit activities — including scoping, evidence collection, stakeholder preparation, and findings remediation.
  • Oversee remediation tracking for audit findings and compliance gaps, ensuring timely closure with appropriate accountability.
  • Serve as the primary point of contact for regulators, external auditors, and certification bodies on all GRC-related matters.

Training & Security Awareness

  • Oversee the design and delivery of a role-based security awareness and compliance training program, ensuring coverage of telecom-specific regulatory obligations.
  • Drive a culture of security and compliance awareness across the organization through targeted campaigns, metrics, and executive sponsorship.
  • Measure training effectiveness and adjust programs based on outcomes and emerging risk areas.

Incident & Crisis Governance

  • Provide GRC oversight for security, privacy, and telecom compliance incidents — ensuring regulatory notification obligations, documentation requirements, and post-incident review processes are met.
  • Maintain current knowledge of applicable federal, state, and international privacy laws, telecommunications regulations, and accreditation standards.
  • Collaborate with the Security Operations and Legal teams to ensure incident response plans reflect regulatory and contractual obligations.

Stakeholder Engagement & Executive Advisory

  • Act as a trusted advisor to the CISO, executive leadership, and the Board on matters of information security risk, compliance posture, and regulatory change.
  • Partner with Legal, Finance, HR, Product, Engineering, and Network Operations to embed GRC practices into business processes and technology delivery.
  • Represent the GRC function in cross-functional governance forums, steering committees, and customer-facing engagements where security assurance is required.
