About this role
Coupang's Seattle office is building out its Red Team and seeking a penetration tester with at least five years of offensive security experience. You'd conduct penetration testing across web, mobile, API, and network environments, then translate your findings into actionable remediation guidance for engineering teams. The role also includes threat actor simulation activities, meaning you'd be designing and executing Red Team campaigns to test Coupang's defenses against realistic attack scenarios.
To succeed here, you need solid technical depth: proficiency with standard penetration testing tools like Burp Suite and Metasploit, strong command-line and Linux skills, and the ability to write scripts in Python or Java to extend your testing capabilities. You should understand OS security fundamentals and networking protocols well enough to move fluidly between different attack surfaces. If you have cloud security experience (particularly AWS), offensive security certifications like OSCP, or background in e-commerce, those will strengthen your candidacy. The role is in-office in Seattle and offers a base salary of $152,000 with standard benefits including equity consideration, annual bonus potential, and 18–21 days of PTO.
