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

Learn more at marketplace.b12.io.

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.

Job Description:

B12's engineering team views software as a craft, but improving the world as the reason to practice it. Our engineers are responsible for prioritizing, conceptualizing, co-designing, building, testing, and engaging users for any concept we are building out. We’re generalists in encouraging each other to experience the full stack, but we’re also aware of each other’s preferences in the stack. For this role in particular, we’re searching for a full-stack engineer who brings strong backend skills (and an interest in using them) to the product. We mentor and teach where we can, both inside and outside of the company.

We value sharing our work with the outside world. Our team has published papers on forming expert flash teams and machine-mediated worker hierarchies. We’ve baked our research into Orchestra, the system that coordinates our expert and machine teams, and released Orchestra into open source to contribute our software back to the community.

We hope our engineers have more longevity than any one tool we use, but here is a sampling of our current thoughts about technology:

• We live on Python/Django and TypeScript/React.
• We store blobs in Amazon’s S3, munch on them in Amazon’s EC2, develop in Docker, and deploy containers to Amazon’s Elastic Beanstalk.
• We believe PostgreSQL should be the first system you consider when thinking about persisting structured data.
• We clean and centralize data in Amazon’s Redshift, and are able to answer almost any question in SQL.
• We leverage AI in our product and our internal tooling, and faced with a landscape in constant flux, try to pick the right model or agent on a task-by-task basis.
• We have near-full test coverage on the backend, and are making progress on our frontend and integration tests.
• We set up continuous integration and deployment because, while this model comes with its own pains, we’ve disliked being on fixed release schedules on previous projects.
• We like to move fast and support point-in-time recovery :).

You’d be a good fit if

• You have at least 4 years of experience building products and systems in production.
• You are an amazing communicator.
• You feel comfortable managing your time and deciding among competing priorities.
• You are passionate about the future of work.
• You enjoy learning and teaching.
• You have some mobile experience.
• You are comfortable working with backend and frontend technologies, but have a deeper background and interest on the backend side.
• You care about and want to contribute to our mission of helping people do meaningful work.

Don’t fear:

• We're somewhat flexible on the number of years of previous experience for this role. We highly favor talent and interest.
• Some candidates may see this list and feel discouraged because they don’t match all the items. Please apply anyway: there’s a good chance you’re more wonderful than you think you are.
• B12 is a safe place for human beings. We particularly encourage you to apply if you identify as a woman, are a person of color or other underrepresented minority, or are a member of the LGBTQIA community.

How to apply

Please provide:

• A pointer to your CV, resume, LinkedIn profile, or any other summary of your career so far.
• If you have a profile on websites like GitHub or other repositories of open source software, you can provide that as well. If you don’t have one, it’s still very possible for us to get along just fine!
• In addition to the traditional application details, we also ask that you complete a small technical challenge below. Two notes:
  • By virtue of submitting your application via a public platform like GitHub, it's possible for people to search for projects with "B12" in the repository name/description/contents and see that you have applied. You can obfuscate these details for your privacy, but contact us if you could benefit from a slightly different process to further protect your privacy.
  • We’ve never tried a “write code to apply to B12” exercise before, and introduced it because of a recent deluge of AI-generated/AI-mediated applications that has made reviewing inbound applications infeasible for us. We hope that introducing this exercise results in a smaller number of qualified candidates without serving as too much of an impediment. You are welcome to use AI assistance on this exercise (we did!). We imagine we’ll iterate on this experiment, and very much welcome your feedback on your experience.

To submit an application, create the following Python script that is executed via a GitHub Action (or continuous integration on any other Git forge). The script should:

• POST to https://b12.io/apply/submission with the following JSON-encoded payload in the body. All fields are required:
  

  {

    "timestamp": "2026-01-06T16:59:37.571Z",

    "name": "Your name",

    "email": "you@example.com",

    "resume_link": "https://pdf-or-html-or-linkedin.example.com",

    "repository_link": "https://link-to-github-or-other-forge.example.com/your/repository",

    "action_run_link": "https://link-to-github-or-another-forge.example.com/your/repository/actions/runs/run_id"

  }

  • Make the timestamp an ISO 8601 timestamp
  • The action_run_link is a page similar to https://github.com/marcua/ayb/actions/runs/20561457327 (might differ if you’re using a forge other than GitHub), which allows us to see the continuous integration run that POSTed to B12
  • We’ve pretty-printed for readability here, but the post body should contain no extra whitespace (compact separators), have keys sorted alphabetically, and be UTF-8-encoded. For example, the canonicalized payload above is
    {"action_run_link":"https://link-to-github-or-another-forge.example.com/your/repository/actions/runs/run_id","email":"you@example.com","name":"Your name","repository_link":"https://link-to-github-or-other-forge.example.com/your/repository","resume_link":"https://pdf-or-html-or-linkedin.example.com","timestamp":"2026-01-06T16:59:37.571Z"}

• Include a header called X-Signature-256 in the post request
  • The value of the header should be sha256={hex-digest}, where the hex digest is the HMAC-SHA256 of the raw UTF-8-encoded JSON request body, using the signing secret as the key.
  • Use a signing secret of hello-there-from-b12 (yes, it’s public, but treat it like a secret in your implementation ;))
  • As an example, the payload above will have a hex digest of c5db257a56e3c258ec1162459c9a295280871269f4cf70146d2c9f1b52671d45
• If the POST is successful, you will receive an HTTP 200 with a response of
  '{"success": true, "receipt": "your-submission-receipt"}'
  • Print that receipt in your continuous integration task
  • To confirm your submission, copy/paste the receipt into the field below
