What You'll Do

Who We're Looking For

  • We care more about how you think and operate than whether you have worked in exactly the same category before.
  • 5+ years of relevant experience in e-commerce, marketplace management, business development, commercial strategy, or a related field preferred.
  • Strong hands-on experience with Korean e-commerce platforms such as Naver Smart Store and Coupang.
  • Experience working with D2C / Shopify or a comparable e-commerce environment.
  • Strong commercial acumen and confidence working with revenue, margin, AOV, CVR, ROAS, pricing, discount mechanics, product mix, and unit economics.
  • Able to translate data into commercial decisions and actions — not just reports.
  • Strong structured problem-solving skills: able to break down ambiguous business problems, identify key drivers, form hypotheses, and recommend a path forward.
  • High ownership and independence: comfortable making decisions within your scope and driving work forward without waiting for repeated direction.
  • Hands-on and execution-oriented: willing to move between strategy, analysis, and detailed implementation when needed.
  • Resourceful and self-directed: able to find information, learn unfamiliar areas quickly, and operate effectively even when processes or data are not perfect.
  • Strong prioritization and project management skills, with high attention to execution quality.
  • Strong Excel / Google Sheets skills and comfort working with commercial datasets. Experience with BI tools such as Tableau or Looker is a plus.
  • Strong communication and stakeholder management skills across different functions and seniority levels.
  • Experience working in a multinational or cross-cultural environment is strongly preferred.
  • Native-level Korean and strong professional English, both written and verbal.

What Success Looks Like

  • a clear understanding of the performance and key growth drivers of Shopify, Naver, and Coupang.
  • Take independent ownership of your channels and key commercial initiatives.
  • Establish clear targets and visible performance tracking.
  • Execute promotions and commercial initiatives accurately and on time.
  • Develop strong working knowledge of Emma's products, consumers, unit economics, and competitive landscape.
  • Identify and implement concrete opportunities to improve revenue, margin, conversion, and customer experience.
  • Bring data-backed recommendations and scalable growth ideas to the team — rather than waiting for the next task.

Why join Emma Korea?

  • Ownership, not micromanagement
  • Business impact, not just task execution
  • Commercial problem-solving, not just reporting
  • Building and scaling, not just maintaining
