Role Overview

Coupang is seeking a highly skilled Security Architect to help design, build, and scale secure enterprise platforms and services that protect our business systems, infrastructure, and internal applications.

As a Security Architect, you will work closely with engineering, platform, and security teams to design secure solutions across identity and access management, authentication, authorization, credential management, cryptography, and data protection domains. You will provide technical leadership within your area of expertise while remaining hands-on in architecture design, software development, security automation, and platform engineering.

This role is ideal for experienced security professionals who enjoy solving complex technical challenges, building scalable security platforms, and enabling engineering teams to deliver secure-by-design systems in a fast-growing technology environment.

What You Will Do

Design and implement security architectures for enterprise platforms, services, and large-scale distributed systems.
Partner with software engineering, infrastructure, and platform teams to integrate security requirements into system design and development processes.
Develop secure solutions across identity and access management (IAM), authentication, authorization, credential management, cryptography, and data protection domains.
Design and improve authentication and authorization services using modern identity standards such as OAuth 2.0, OpenID Connect (OIDC), and federation technologies.
Build and automate security controls, tooling, and services using software engineering best practices with a strong focus on scalability, reliability, and operational efficiency.
Review system architectures and provide security guidance to engineering teams throughout the software development lifecycle.
Contribute to the design and evolution of enterprise IAM platforms, access control frameworks, and credential management systems.
Establish and promote security best practices related to secure system design, cryptography, secrets management, and access governance.
Identify security gaps, evaluate technical risks, and recommend practical solutions that balance security, business needs, and engineering productivity.
Develop prototypes, proof-of-concepts, and security automation solutions primarily using Python and related technologies.
Collaborate with cross-functional stakeholders to continuously improve Coupang's overall security posture and operational maturity.
