Senior Staff Security Architect Role Overview Coupang’s Security Architects play a critical role in defining and governing the security architecture that protects Coupang’s internal business systems, infrastructure, and enterprise platforms at scale. As a Security Architect, you will own the security strategy, standards, and architectural direction across identity, authentication, authorization, credential management, cryptography, and data protection domains. You will act as a principal technical leader, partnering closely with engineering and platform teams to build secure-by-design systems while driving security automation and operational excellence across the organization. This role is highly hands-on. While responsible for architectural leadership and policy definition, you will also contribute to software development, automation initiatives, and technical implementation to enable scalable security solutions throughout Coupang. What You Will Do - Architect and scale enterprise security foundations for Coupang’s rapidly growing business, establishing reference architectures, security standards, and governance frameworks across identity and access management, authentication, authorization, cryptographic services, and data protection. - Design and implement security architecture for large-scale distributed systems, ensuring secure access to business-critical applications, infrastructure, and internal platforms. - Define and govern security policies, authorization models, policy languages, and security frameworks that enable consistent implementation across engineering organizations. - Build security automation solutions and security platforms using modern software engineering practices, with a focus on improving scalability, consistency, and operational efficiency. - Partner closely with software engineers, infrastructure teams, platform owners, and security leaders to embed security requirements into system design and development lifecycles. - Drive the architecture and evolution of identity and access management ecosystems, including authentication systems, authorization services, credential management platforms, and enterprise access control frameworks. - Review complex system designs and provide architectural guidance for highly secure environments, balancing business requirements with security, scalability, and operational needs. - Establish best practices for applied cryptography, key management, PKI infrastructure, and secure credential lifecycle management. - Contribute hands-on technical solutions through coding, prototyping, automation, and security tooling development, primarily leveraging Python and related technologies. - Continuously improve Coupang’s security posture by identifying security gaps, evaluating emerging technologies, and driving strategic security initiatives across the organization.
