Security Architect

AppsFlyer’s Security team is seeking a Security Architect to drive cross-PR&D security alignment, lead complex security design reviews, and shape the security architecture of our strategic cross-technology initiatives. This role serves as the senior technical security authority across our R&D ecosystem- partnering with product, platform, and infrastructure teams to embed security into every layer of our Secure Software Development Lifecycle (SSDLC) and to guide AppsFlyer toward a robust, modern, and secure architecture.

The ideal candidate is highly professional, demonstrates a ‘can-do’ attitude, and brings the seniority and presence to engage R&D architects and senior stakeholders as a peer. You will need strong technical depth, excellent communication skills, and the ability to translate complex security considerations into clear business and engineering decisions across a diverse range of stakeholders.

• Drive cross-PR&D alignment of the Secure Software Development Lifecycle (SSDLC), establishing consistent standards, controls, and practices across all engineering groups.
• Lead complex security design reviews for new technologies, systems, services, and strategic cross-tech initiatives.
• Define and own the security architecture for high-impact cross-team initiatives, ensuring security is embedded from the earliest design stages.
• Serve as the security counterpart to PR&D architects- representing security in architecture forums, design discussions, and strategic technology decisions.
• Partner with DevOps, Infrastructure, Platform, and R&D teams to integrate security into CI/CD pipelines, infrastructure-as-code, and shared platform services.
• Perform threat modeling and architectural risk assessments to identify and mitigate weaknesses before they reach production.
• Develop and maintain security guidelines, reference architectures, and best practices that scale across the organization.
• Evaluate and recommend security tools and technologies to continuously strengthen AppsFlyer’s security posture.

• Experience working in a SaaS product company at scale.
• Excellent communication skills, with the ability to translate complex technical risks into clear business impact and to influence senior R&D stakeholders.
