Responsibilities

We are seeking an External Security Relations & Assurance lead to serve as the primary trust and assurance interface between our security organization and external clients, partners, and regulators. This role combines deep client security expertise with a customer-service-first mindset - you will be the person clients turn to when they need confidence in our security posture, and the person who translates their concerns into actionable internal priorities. This is a net-new role designed to elevate how we deliver security assurance to external stakeholders. You will own the end-to-end client security assurance lifecycle: from initial client security inquiries and due diligence requests, through tailored security narratives, evidence packages, and continuous relationship management. Think of this as a senior individual contributor role where you are both a security expert and a customer experience leader - ensuring every client interaction with our security team is consistent, professional, and trust-building. Key Responsibilities - Own external client and partner security inquiries end-to-end, from intake through delivery - Produce client security assurance deliverables (security narratives, architecture briefs, assurance packages) that are accurate, tailored, and ready for external sharing without rework - Build and maintain trust-based relationships with sales teams - Lead client-facing security briefings that translate complex technical controls into clear, business-relevant language that moves deals forward - Embed into our advertising products, understand the architecture, product specs, and where the security risks live, so assurance is grounded in reality - Understand the sales lifecycle, know where a deal is, what's needed, and when, and deliver assurance is critical - Define and enforce a client security response model with SLAs, escalation paths, and quality standards - Understand each key client's security requirements, regulatory obligations, and risk appetite, tailor every response accordingly - Maintain a client security knowledge base that enables fast, consistent, and accurate responses to recurring questions - Partner with Legal, Privacy, Compliance, and Product Security to ensure every client-facing representation is approved and airtight before it goes out - Review client RFPs, vendor questionnaires and identify gaps between expectations and current posture before the client does - Find and drive opportunities to automate and standardize client security response processes
