Summary Generated by Built In

We built Bubble with a clear mission: to empower everyone to create software. Our AI visual development platform lets anyone, from first-time entrepreneurs to enterprise teams, take an idea from prompt to fully-functional, scalable app across web, iOS, and Android. With over 6 million users in more than 100 countries, Bubble is breaking down the barriers to entrepreneurship and innovation worldwide.


Our Product

Bubble is the only fully visual AI app builder that lets you vibe code without the code to go beyond prototypes and launch real apps to real users. Chat with AI when you want speed, edit directly when you want control. Bubble's visual editor lets you fine-tune any detail, from the design to privacy rules and programming logic, so you're never stuck, even if AI hits its limits. Everything you need comes built in: a unified web and native mobile editor, enterprise-grade hosting, security, database management, and automatic scaling that grows with your business.
You can build just about anything on Bubble, and our community is living proof. Mailead grew a $10K investment into a $2M valuation, and Faceless.video went from zero to $1M+ ARR in under a year. People aren't just launching products on Bubble, they're building real businesses. See how Bubble builders are shipping apps that change industries, solve problems, and shape the future here: Inspiring builders, breakthrough apps.


Why Join Bubble Now?

The rise of AI-generated software has validated everything Bubble has been building toward for over a decade. But pure AI-generated code is fragile, hard to debug, and rarely production-ready. Bubble bridges that gap, combining the speed of AI with a structured visual platform that produces stable, scalable, secure software. The people who join Bubble right now will help define what that means for millions of builders around the world. If you've ever wanted to work on something that genuinely changes who gets to build, this is your moment.

About the Team:

We’re expanding our AI Engineering Team to build next-generation AI-powered development workflows—enabling users to describe their applications in natural language and have AI generate, modify, and enhance their apps seamlessly.

As an Applied AI Engineer, you will help define and ship the future of AI-powered development at Bubble. This is an engineering role, not a research role. You’ll own LLM-driven product features end-to-end, design agentic workflows that real users depend on, and collaborate closely with Product, Infrastructure, and Research to push the limits of AI-driven development.

You’ve shipped LLM-powered features in production. You know what makes agents fail. You’re comfortable moving across TypeScript and Python. If that’s you, read on.
What You'll Do:

  • Design and build agentic workflows that enable multi-step AI-driven app generation for real users at scale.

  • Improve LLM reasoning and retrieval techniques to enhance Bubble’s AI-powered development tools.

  • Build and maintain production LLM pipelines—including prompt engineering, evaluation frameworks, and latency optimization.

  • Fine-tune and optimize LLMs for AI-assisted app-building workflows using proprietary Bubble datasets.

  • Own AI feature quality end-to-end: from prototype through eval, deployment, and monitoring.

  • Work closely with the AI team to scale AI research into production systems.

About you:
5+ years of industry experience as a Software or Machine Learning Engineer, or a Master’s/PhD in AI, ML, or NLP with 3+ years of production experience.

  • A track record of shipping LLM-powered features in production—not just API integrations, but real systems with evals, monitoring, and iteration.

  • Hands-on experience building agentic AI workflows and debugging multi-step agent failures.

  • Strong command of RAG, context engineering, and retrieval pipeline design.

  • Experience with transformer models, embeddings, and AI model evaluation.

  • Proficiency in Python for AI/ML work and comfort working in a TypeScript/Node.js codebase.

  • Familiarity with tools like Hugging Face, LangChain, or Mastra.

  • Excellent communication skills and a collaborative, product-minded approach.

  • Alignment with our values: a desire to empower others, a focus on team and user success, and a willingness to experiment and learn from failures.

The Company
HQ: New York, NY
140 Employees
Year Founded: 2012

What We Do

Founded in 2012, Bubble was one of the first companies to bet that software creation shouldn't require code. Over a decade later, that bet has scaled to 6million+ users and over 200 countries building real, revenue-generating products on the platform. Now, as AI reshapes how software gets built, Bubble is becoming an agentic company, not just adding an AI feature, but rebuilding around the Bubble AI Agent as a core part of the product, with Bubblers using tools like Claude Code, Cursor, and Figma Make as everyday parts of how they build. The people who join now are defining what that looks like for millions of builders. This does two things the current copy doesn't: gives a timeline (2012 → 6M+ users → the current AI-era pivot) and states the agentic-company positioning in plain terms, matching the exact language used across LinkedIn and Instagram so a candidate sees the same story everywhere they research Bubble.

Why Work With Us

You are trusted to do the job you were hired for on day one. There is a team of passionate, smart, kind, selfless people who have your back. We are devoted to changing the way people use technology. Our mission is real and attainable. We are nerdy and gritty, and also fun.
