AI Developer Marketing Co-Founder

AI Developer / Growth Co-Founder (Equity Only)

 Job description
 ShapeMint is building AI-powered custom 3D product
 experiences. We’re looking for an early-stage co-founder type
 who can both build and market.

 This is not a passive internship. You’ll work directly with
 the founder to ship product improvements, build growth
 systems, test landing pages and messaging, and help shape the
 company’s go-to-market strategy from the ground floor.

 This role is best for someone who is genuinely strong at
 both:

 - AI-assisted software development
 - growth, content, and consumer marketing

 You should already be comfortable using modern CLI coding
 agents in real workflows. Direct experience with Claude Code,
 Codex, or similar agentic coding tools is strongly preferred.
 You should also know how to turn product work into traction
 through landing pages, experiments, positioning, and content.

 What you’ll do

 - Build and ship product features using AI coding agents
 - Create and iterate landing pages for niche audiences
 - Run growth experiments on positioning, offers, and
   conversion
 - Help develop content, messaging, and distribution strategy
 - Use AI tools to move faster across engineering and
   marketing
 - Work directly with the founder on product and company
   direction

 What we’re looking for

 - Experience using Claude Code, Codex, or similar CLI coding
   agents in real projects
 - Strong builder mindset and comfort shipping fast
 - Strong marketing instincts, especially for consumer
   products
 - Ability to write clear copy and create compelling
   positioning
 - Comfortable wearing multiple hats in an early-stage startup
 - Excited by ownership, ambiguity, and building from zero

 Nice to have

 - React, TypeScript, Next.js, or modern frontend experience
 - Experience with AI products or agent workflows
 - Landing page, paid social, or growth/content experiment
   experience
 - Interest in startups, product strategy, and brand building

 Compensation
 This role is equity-only at this stage. Compensation will be
 an equity package based on experience, contribution level,
 and long-term fit. There is currently no cash salary or
 hourly pay.

 Why this role

 - Direct access to the founder
 - Real ownership over product and growth
 - Chance to help shape an AI-native company very early
 - Strong portfolio and startup-building experience
 - Flexible remote, part-time structure to start

 Application note
 Please apply only if you have hands-on experience using AI
 coding agents and you’re excited about combining technical
 execution with marketing/growth. In your application, include
 1 to 3 examples of products, experiments, or campaigns you’ve
 built, especially anything using Claude Code or similar
 tools.
