About the role

We’re looking for a Marketing Manager who’s equal parts marketing + project management: someone who can run multiple moving pieces, coordinate people, and take initiatives from idea, execution, measurable result.
 

A big chunk of the job is events (online and potentially offline), but it’s not only events — you’ll also help launch small growth experiments (landing pages + traffic) and coordinate creatives and contractors.
 

What you’ll do

  • Invite and coordinate ~10 speakers per Space
  • Build agenda + flow (host/moderator coordination)
  • Drive traffic / attendance
  • Manage pre-announcement + post-announcement content and follow-ups
• Support offline events / conferences (if needed): logistics + coordination + timelines.
• Launch quick experiments:
  • Create a landing page for an idea
  • Coordinate design/copy/dev if needed (freelancers are available)
  • Run traffic to validate the idea and report results
• Coordinate a small marketing “pod”: work with SMM, researchers/analysts (deep research for content), designer, and freelancers.
• Write clear briefs, set deadlines, and make sure tasks are actually shipped.
   

What we’re looking for

• 1+ year of hands-on marketing experience in web3.
• Strong project ownership: you can manage multiple parallel tasks and people without dropping the ball.
• You’re reliable and execution-driven (“go and do”), focused on outcomes.
• Comfortable with event ops (online events especially) and coordinating speakers/partners.
• Can set tasks for designers/contractors, review deliverables, and iterate quickly.
• English: confident working level (async + calls when needed).
   

Nice to have

• Experience running Twitter/X growth loops and community-facing launches.
• Paid traffic basics (you don’t have to be a performance marketer, but should understand how to test).
   

Location & travel

• Full-time, Remote, EU-friendly time zones.
• Ability to travel occasionally (optional, but preferred when relevant).
