Full-stack Developer

Bottn is the first open, monetized marketplace for GPT-based Al bots. We enable developers, freelancers, and creators to build, price, and distribute domain-specific assistants for businesses and consumers.

We're pre-launch with a fast-growing waitlist across 60+ countries, and now we're hiring a freelance Lead Developer to build the platform MVP.

This is a hands-on role for an experienced full-stack developer who's excited to build in the Al space and work closely with product and design to bring a lean, well-scoped marketplace to life.

What you'll do:

- Build the first working version of the Bottn platform (creator dashboard, bot profiles, payments)

- Integrate OpenAl APls and set up scalable bot deployment infrastructure

- Implement user auth, search, content moderation, and basic analytics

- Work closely with design and product to shape clean, efficient user flows

- Ship fast, with a focus on stability, usability, and lean architecture

- Help set up hosting, deployment, and backend architecture for growth

What we're looking for:

- 3+ years building full-stack web applications (Node.js, Python, or similar)

- Experience with marketplace or SaaS-style products

- Comfortable integrating third-party APls (OpenAl, Stripe, etc.)

- Clear thinking around database structure, user auth, and secure deployments

- Familiarity with hosting platforms like Vercel, AWS, or GCP

- Comfortable giving/receiving feedback early and weekly progress updates

Bonus: Experience with prompt orchestration, LLMOps, or vector databases

What we offer:

- Freelance contract (20-30 hrs/week, project-based)

- Fully remote and async-friendly, although Tallinn-based is preferred

- High ownership over product architecture and execution

- Opportunity to shape a visible, high-traction product in a fast-moving space
