Role Overview

Coupang’s AI Security Architects play a critical role in safeguarding our technology ecosystem by designing, defining, and governing the enterprise-wide security architecture for all artificial intelligence and machine learning platforms. As a AI Security Architect, you will establish standard reference architectures, model safety frameworks, and risk governance protocols across the organization. You will act as a principal technical leader and ambassador, championing Coupang’s leadership principles while embedding secure-by-design standards into our next-generation AI infrastructure.

What You Will Do

• Architect and scale secure AI/ML foundations for Coupang’s rapidly expanding business by designing end-to-end security blueprints, threat modeling complex pipelines, and establishing enterprise standards for secure model lifecycles.
• Employ a data-driven approach to AI risk management and threat governance. Define key security risk metrics, evaluate platform posture, and ensure architectural alignment with organizational objectives.
• Build close relationships with key stakeholders, including principal software engineers, enterprise architects, development leaders.
• Acquire in-depth knowledge of the business domains and specialized security demands for emerging technology platforms (e.g., LLM guardrails, agentic systems, real-time data privacy, and secure cloud MLOps infrastructure).
• Rapidly respond to our evolving technical and threat landscape, aggressively driving architectural innovations to create a world in which our customers ask, “How did I ever live without Coupang?”
• Improve the AI security ecosystem by reviewing system designs, auditing high-risk architectures, and authoring technical governance standards to prevent data leakage, model inversion, and pipeline compromise.
• Enhance developer efficiency and system reliability by delivering friction-free security frameworks, automated compliance patterns, and guidance during high-severity architectural security reviews.

Basic Qualifications

• Bachelor’s degree in computer science, Cybersecurity, Computer Engineering, or a related field, and 6+ years of total experience in technology, with significant focus on enterprise architecture, cloud security, or software security design.
• Deep architectural knowledge of AI/ML systems, cloud infrastructure (AWS/GCP/Azure), and specialized security threats unique to AI (e.g., prompt injection, model theft, data poisoning, and OWASP Top 10 for LLMs).
• Demonstrated experience authoring threat models, enterprise security standards, and secure reference architectures for complex, distributed applications.
• Ability to solve high-impact architectural challenges through systemic thinking, creative problem-solving, and cross-team consensus.
• Ability to influence senior technical leaders and drive strategic security adoption across business units through executive-level communication.

Preferred Qualifications

• Recognized industry credentials in architecture or security (e.g., SABSA, TOGAF, CISSP-ISSAP, CCSP) alongside demonstrated hands-on experience with AI/ML systems.
• Deep expertise in regulatory compliance, confidential computing, differential privacy, and data protection regulations (e.g., PII handling in AI models).
• Experience leading AI security transformation or building zero-trust AI platforms within a high-growth tech company, large-scale e-commerce ecosystem, or global cloud environment.
