About the role

The Role:

We’re looking for a Founding Engineer to join us in building out the core product at a0.dev. If you’re a full stack engineer who’s passionate about mobile app development, obsessed with great developer tools, and excited about using AI to make app development even easier than web development, we’d love to talk.

As a founding team member, you’ll have outsized impact—not just on the codebase, but on the product, culture, and direction of the company. You’ll work in-person directly with the founders and take ownership of important parts of our stack.

What You’ll do:

You’ll work directly with the founders to:

  • Build and ship core product features daily across our Next.JS and React Native app and work closely with our designers.
  • Create Backend Services and Infra that are consumed across many different clients, internally and externally, over WebSocket and HTTP
  • Develop AI Agents to automate the app dev lifecycle—everything from code to deployment on the app store
  • Support Users and identify pain points and quickly ship fixes and improvements
  • Rigorously test the a0.dev app creation process and build and launch your own mobile apps using a0.dev that earn money on the app store.

What We’re Looking for:

  • Strong Typescript and Next.JS Experience
  • Strong React Native Experience
  • Willing to work 5 days/week in-person in San Francisco
  • Strong communication skills
  • Experience with Supabase / Postgres
  • Back-end development experience
  • High Agency: Able to figure things out without much hand-holding
  • Good Vibes and Startup Energy: We’re a small scrappy team looking for someone who’s excited about our mission, able to move fast, and fits well with our team.

Why Join Us:

This is an incredible moment in time to be building with AI. When people think of their favorite software it’s often a mobile app, yet creating and monetizing mobile apps has always been much harder than creating websites. If you’re excited about creating a world where users can turn their app ideas into revenue generating business in minutes, this is the role for you.

About a0.dev

a0.dev is a platform that helps mobile developers build high quality apps in days instead of weeks by generating custom react native projects. We've launched top ranking apps that have been used by hundreds of thousands, and now we're creating the tools we wish we had to build faster.

Our goal is to ship to millions of mobile apps over the next few years by making app development even easier than mobile development.
