Scored from the posting itself — how clearly the role is described, how much it says about pay and benefits, and how recently it was listed. Not a judgement of Coupang Internal as an employer.

What you need

  • Demonstrated hands-on penetration-testing capability across web, mobile, or API environments.
  • Demonstrated ability to use penetration-testing tools in Linux or command-line environments.
  • Ability to assess vulnerabilities, explain supporting evidence and impact, and provide actionable remediation guidance.
  • Programming or scripting capability that supports security testing.
  • Offensive-security experience sufficient to execute defined penetration-testing activities with appropriate support.
  • Ability to communicate security findings and remediation guidance in English and Traditional Chinese.

Nice to have

  • Experience completing scoped penetration-testing activities with clearly defined support, requirements, and testing boundaries.
  • Experience responding constructively to technical direction, review feedback, and newly identified testing requirements.
  • Experience testing multiple applications, external services, or internal applications through penetration testing or legally authorized bug-bounty work.
  • Experience in e-commerce, banking, web services, or other complex application environments.
  • Exposure to cloud-security testing, including architecture, identity and access, public interfaces, or configuration risks.

Worth weighing

  • No salary listed.
  • The role requires collaboration with teams in Korea, which may involve time zone challenges.
  • The position is described as L5, indicating it is for a developing penetration tester, which may imply a focus on growth rather than senior-level autonomy.
  • The recruitment process includes multiple interview stages, which may be time-consuming for candidates.
