Main Responsibilities:

• Client Assurance: Act as the primary point of contact for client assurance requests, including security, privacy, compliance, and supply-chain risk inquiries. Coordinate and manage responses to customer due diligence questionnaires, audits, and assurance reviews (e.g., SOC, ISO, regulatory requests). Partner with Security, Data Privacy, Legal, and Engineering teams to deliver clear, consistent, and high-quality assurance responses. Drive continuous improvement in client assurance processes to reduce friction and response time.
• Vendor Due Diligence and Supply Chain Lifecycle: Own and manage the end-to-end third-party risk lifecycle, including onboarding, risk assessment, contracting, ongoing monitoring, and offboarding. Design and execute vendor due diligence reviews across security, privacy, operational resilience, and regulatory risk domains. Collaborate with Legal, Data Privacy, Security, and Business stakeholders to ensure risk-appropriate controls and remediation plans are in place. Maintain risk tiering, review cadences, and escalation paths aligned to business and regulatory requirements. Oversee procurement processes and licensing management to ensure all third-party solutions are sourced in compliance with company policy and regulatory standards. Work collaboratively with Technology, Legal and Finance to maintain accurate software inventories, manage renewals, and optimise cost-effectiveness while mitigating contractual and compliance risks. Develop and maintain third-party assurance frameworks, policies, and procedures. Track and report on third-party risk metrics, trends, and remediation status to senior stakeholders. Support internal and external audits related to third-party risk and supply chain assurance. Stay current on evolving regulatory expectations and industry best practices related to third-party and supply chain risk. Provide oversight of the AI Management System, ensuring robust governance, risk management, and compliance practices are in place throughout the third-party risk lifecycle. Coordinate ISO 42001 readiness activities, aligning internal controls and vendor due diligence processes to the requirements of the AI management standard. Monitor evolving best practices and regulatory developments in AI governance, supporting continued compliance and operational excellence.
• TrustCenter & Vendor Portal Ownership: Lead and nurture teams, building a culture centred around user service, documentation, and proactive engagement. Recruit, mentor, and develop talented employees, defining clear career paths and performance expectations focused on service excellence. Encourage continuous improvement and innovation in support, training, and user communication. Provide strategic oversight of the TrustCenter, ensuring assurance materials are accurate, up to date, and aligned with company risk posture. Own and continuously improve the Vendor Portal, enabling transparency and efficient information sharing with clients and partners. Define content strategy, governance, and operating model for assurance artifacts published externally. Partner with Product, Security, and Communications teams to enhance usability and trust signals.

Qualifications: 2+ years of experience in third-party risk management, assurance, compliance, security, or audit.

Familiarity with common assurance frameworks (e.g., SOC 2, ISO 27001, ISO 42001, NIST, GDPR, vendor risk standards). Proven ability to work cross-functionally and influence without authority. Excellent written and verbal communication skills, particularly in explaining risk to non-technical audiences.
