🚀 AI Marketing Automation Developer Intern

AI-First | High Ownership | Long-Term Opportunity

📍 About the Role

We are building an AI-first marketing and communications engine across multiple products and brands.

This role is for someone who wants to use AI to eliminate manual work, not do more of it.

This is not a traditional marketing internship.

It is a builder role focused on automation, experimentation, and systems thinking.

🧠 How We Work

• AI-first, automation-first mindset
• We focus on outcomes, not activity
• You will work independently on clearly defined objectives
• Minimal meetings, maximum ownership
• Trial, iterate, break, fix, and improve
• What you build is expected to be production-ready, not just a demo

We use modern AI tools (including Cursor and LLMs) and expect you to learn fast and apply faster.

✅ Who This Is For

This role is a strong fit if you:

• Think in terms of systems and leverage
• Enjoy solving open-ended problems
• Are comfortable with ambiguity
• Like experimenting until something works
• Want to work in a real AI-first environment, not just talk about AI

Background matters less than mindset.

Engineering, tech-savvy marketing, or self-taught AI backgrounds all work.

❌ Who This Is NOT For

• Manual or repetitive marketing work
• Copy-paste or template-only roles
• People who need detailed step-by-step instructions

🌱 Growth & Long-Term Path

This is a long-term internship, not a short project.

Interns who:

• Consistently deliver
• Show ownership
• Fit into our AI-first work culture

👉 Will be converted to full-time roles.

Hiring and conversion decisions are made jointly by the founders and the automation team lead.

🕒 Commitment

• 20–30 hours per week minimum
• Fully remote
• Flexible working hours (output > hours)
