AI Vibe Coding Web Designer

The Role
We’re an AI Website Builder that allows businesses to create beautiful, functional websites and applications. Customers can generate complete websites and applications from the ground up using our coding agent. Instead of manually assembling layouts, users prompt an AI agent that builds structure, content, and design in seconds. You can also edit the code anytime you want.

To support our community of millions of users, we are expanding the B12 Expert Marketplace and onboarding experts with strong technical foundations who are excited about vibe coding and AI-first website creation.

As a Marketplace Partner, you will work directly with B12 customers on DIY plans who want professional support building, refining, or enhancing their AI-generated sites. This is an independent freelance partnership opportunity for experienced builders who are comfortable directing AI output and stepping into code when needed.

How the Expert Marketplace Works
The B12 Expert Marketplace is a resource for customers on DIY plans who want additional help with design, development, SEO, copywriting, or marketing for their B12 website.

Customers browse the marketplace and choose partners to hire directly.

As a Marketplace Partner:

You set your own pricing and services

Customers contact and hire you directly

You manage communication, scope, and delivery

You operate independently and are not a B12 employee

Refining and regenerating AI-generated sites through structured prompting

Improving layout, hierarchy, clarity, and overall user experience

Applying your coding background when deeper customization is needed

Working directly with customers to scope and deliver projects

Providing feedback that helps improve the Expert Marketplace experience

We Are Looking for Someone Who
Understands AI-first website creation and vibe coding -

You are comfortable building with AI as a collaborator. You know how to guide output through thoughtful prompting, regenerate strategically, and iterate quickly.

Is confident working directly with clients -

You can translate customer ideas into polished, high-quality websites and communicate clearly throughout the process.

Thinks beyond visuals -

You care about structure, usability, and results, not just aesthetics.

Is curious about what is next -

You are excited about how AI is changing the way websites are built and want to be part of that shift.

Bonus Points If

You have worked with small to mid-sized businesses

You have experimented with AI builders or vibe coding workflows

You are comfortable balancing automation with custom code

You enjoy improving systems, not just executing tasks

Important
This is a freelance marketplace partnership, not a full-time position. Partners operate independently and work directly with customers who choose to hire them through the B12 Expert Marketplace.

How to Apply
Submit your resume, portfolio, and LinkedIn profile. If you have examples of AI-assisted builds or experimental workflows, we would love to see them.
