About the Role
Some of the most important ideas in blockchain are also the hardest to explain.
As a Senior Content Writer, you'll help bridge that gap by transforming complex protocol designs, technical concepts, and ecosystem developments into thoughtful, educational, and engaging content.
This is not a technical documentation role. Instead, we're looking for someone who understands blockchain technology deeply enough to explain it clearly to a broader audience.
If you enjoy researching complex topics, asking thoughtful questions, and crafting high-quality educational content, we'd love to hear from you.
Responsibilities
Research and write high-quality educational long-form articles about CKB, blockchain infrastructure, and related topics.
Translate protocol updates and complex technical concepts into clear, engaging content for broader audiences.
Write high-impact content for X, including posts, threads, long-form posts, and thought-leadership quote tweets.
Collaborate closely with researchers, engineers, and ecosystem contributors to ensure technical accuracy.
Review and edit content from other contributors to maintain a consistent editorial standard and tone.
Stay current with industry trends and contribute to broader ecosystem narratives where relevant.
Apply SEO and GEO best practices where appropriate.
Effectively leverage AI tools to improve research, drafting, editing, and writing workflows while maintaining high editorial quality.
Qualifications
Required
4+ years of professional writing experience (7+ years preferred).
Deep understanding of blockchain technology and the broader crypto ecosystem.
Proven ability to explain complex technical concepts in a way that is accurate, engaging, and accessible.
Exceptional written English with strong attention to clarity, structure, and detail. Native-level proficiency is preferred but not required.
Excellent research skills and intellectual curiosity.
Experience writing educational, technical, or research-driven long-form content.
Experience creating engaging content for X (Twitter), including threads and thought-leadership content.
Familiarity with SEO/GEO principles and AI-assisted writing workflows.
Preferred
Experience working with an L1, L2, major DeFi protocol, blockchain infrastructure project, or centralized exchange.
Background in editorial, journalism, research communications, or educational content.
Experience reviewing and editing the work of other writers.
This role is probably not the right fit if your experience has been primarily focused on news reporting, market analysis, or short-form marketing copy.
Application
Please send your application to join@ckba.build with the subject line:
Senior Content Writer – Your Name
Please include:
Your resume
Three writing samples that best represent your work
Ideally, your writing samples should be educational, technical, or research-driven long-form articles (1,000+ words) that demonstrate your ability to explain complex ideas clearly. News articles, market analysis, newsletters, or primarily promotional content are generally not the best examples for this role.
If you've collaborated with others on a piece, please briefly describe your contribution.
Writing is the most important part of our evaluation process. We'd much rather read your best work than a long list of previous employers. If you're an exceptional writer who enjoys explaining complex ideas, we'd still love to hear from you—even if you don't meet some qualification listed above.
