Performance Marketing Manager

ium Labs is a Seoul-based crypto and Web3 marketing agency that helps global projects enter and grow in Korea. We cover GTM strategy, KOL campaigns, PR, community, paid ads, exchange campaigns and local events, from the first brief to the post-campaign review.

As Performance Marketing Manager, you own the numbers behind our partners’ user growth in Korea. You set the right goal for each project, such as sign-ups, KYC, first deposits, trading volume or on-chain conversions, and run paid, KOL and affiliate channels as one funnel.

You manage budgets for several clients at once, explain the results to them, and propose what to do next.

• Experience: 3+ years in performance marketing
• Salary: KRW 50–60M per year, plus a performance-based incentive paid separately

What you’ll do

• Measure KOL and affiliate campaigns: set up referral codes and UTMs, compare conversions by creator, and define payout rules
• Test creatives and landing pages: design A/B tests and run improvement cycles with the design and content team

• 3+ years of hands-on performance marketing, in-house or at an agency
