Let’s start with a hello 👋

If you understand how casino brands really work, know how to hook a mass B2C audience, feel trends before they peak, and think like an arbitrageur — we’re definitely on the same side.

What you’ll be doing

• Develop and execute a B2C SMM strategy for online casino brands.

  • posts and stories,
  • bonus, promo, and tournament announcements,
  • interactive mechanics, contests, giveaways,
  • short-form videos, memes, and trend-based content.
• Build a strong emotional brand image that drives trust and motivation to play.

Who we’re looking for

• Solid understanding of B2C audience acquisition and retention.
• Strong sense of trends, memes, and viral mechanics.
• Ability to create content that engages and converts, not just “looks nice”.
• Knowledge of gambling industry specifics and restrictions.

Nice to have
