Role Overview

The Detection Operations team is responsible for protecting Coupang's global attack surface across web, network, email, and endpoint security. We operate and manage a broad range of security technologies, including enterprise security appliances, endpoint protection platforms, and cloud-based SaaS security services. 

Our mission is to detect, investigate, and mitigate cyber threats before they impact the business. By combining proactive threat detection, rapid response, and in-depth root cause analysis, we help minimize security risks while continuously improving our overall security posture and preventing future incidents. 

Why Join Detection Operations? 

At Coupang, security operates at massive scale. As a member of the Detection Operations team, you will have the opportunity to work across multiple security domains, including: 

• Web Security 

• Network Security 

• Email Security 

• Endpoint Security 

Rather than being confined to a single technology or security domain, you will gain hands-on experience with a diverse set of security solutions and services that protect one of the largest e-commerce and technology platforms in the world. 

You will work closely with experienced security engineers and subject matter experts across multiple disciplines, providing unique opportunities to expand both your technical depth and breadth. Team members are encouraged to take ownership, drive improvements, and contribute directly to strengthening Coupang's security capabilities.
