Original Job Description
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

What You Will Be Doing
Building new websites using B12
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
Has a strong technical foundation – You have 3 to 5 years of experience in web design or front-end development and solid coding skills. Proficiency in HTML, CSS, and JavaScript is required. You should be comfortable reviewing and extending front-end output beyond what AI generates.
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.
