Crypto Twitter Marketing Intern

We’re looking for a highly motivated, extremely online Crypto Twitter Intern (with the intent to convert to Full Time) to help us stay on top of the fastest-moving narratives in crypto. This is a junior role designed for someone who lives and breathes crypto Twitter, moves quickly, thinks clearly, and wants deep exposure to how leading founders and teams build influence, distribution, and narrative in the space.

You’ll be responsible for monitoring crypto Twitter seven days a week, identifying emerging narratives, technical discussions, and high-signal posts from prominent founders, researchers, and intellectuals.

You’ll share concise, high-quality updates with the team and, over time, help draft original content that engages directly with what’s happening online.

This role also supports broader marketing efforts, including event and conference submissions, and plays a key role in supporting the founder’s personal brand.

This is a hands-on, high-expectation role for someone eager to learn, willing to work hard, and excited to get their hands dirty.

• Identify trending posts and conversations worth engaging with or amplifying

• Draft original short-form content (tweets, threads, replies) engaging with identified narratives and posts

• Support the founder’s personal brand by helping surface ideas, trends, and content opportunities

• Assist with general marketing initiatives, including:

  • Event, conference, and community submissions

  • Research and coordination around ecosystem opportunities

• Maintain high standards of accuracy, precision, and signal-to-noise

Requirements

• Strong understanding of crypto fundamentals (protocols, DeFi, infra, governance, market structure, etc.)

• Comfortable engaging with technical concepts and discussions

• Exceptional ability to synthesize large volumes of information quickly

• Highly efficient, organized, and detail-oriented

• Willingness to work hard, move fast, and operate with urgency

Nice to Have

• Experience running or contributing to a crypto-native Twitter account

• Technical background (engineering, research, data, or protocol familiarity)

• Strong instincts for narrative, positioning, and online discourse

• Prior experience supporting founders, creators, or personal brands

This role is best suited for someone who

• Takes ownership and thrives with responsibility

• Is precise, thoughtful, and signal-driven

• Wants to learn by doing and isn’t afraid of unglamorous work

• Understands that crypto moves fast—and is excited by that
