Founding Full Stack Engineer

About the role

Founding Full-Stack Engineer

Ready to build the next generation of AI-native consumer experience?

Text.ai is a consumer-first AI native company, revolutionizing how people communicate in group chats.

We're pioneering an entirely new category of consumer AI products that millions will use daily. We are building the first AI-native communication platform, where every conversation becomes intelligent, collaborative, and effortless. We're reimagining how humans and AI work together from first principles.

While everyone else builds individual AI assistants, we're solving the hardest problem in consumer AI: making multiple humans happy simultaneously through true group intelligence.

Our AI doesn't just respond to prompts. It stays, learns, thinks, and adapts to make every human connection better. From planning the perfect group trip to finding restaurants everyone will love, we transform chaotic group coordination into effortless collaboration.

The future isn't prompt → response.

It's presence → understanding → creation.

We are backed by Y-Combinator, SV Angel, and angel investors from Shopify and Tencent, with founders from Ex-Tesla, Eventbrite, Amazon, & McKinsey.

The Role

We're hiring a Founding Full-Stack Engineer (Frontend/Backend) to be the technical owner and driver of our new app experience. This is a very hands-on role focused primarily on React Native (iOS and Android), along with Backend (Python) integration. You will be joining the founding team and taking the lead on building our mobile app from the ground up, while also contributing to backend integration tasks when needed.

This isn't your first native app launch. You've done this before, you are a seasoned engineer and know how to ship bug-free, polished, and high-performing apps. You'll work closely with design, product, and engineering stakeholders to build intuitive and beautiful experiences, FAST.

What makes this role extraordinary:

- Category Creation: You're not iterating on existing patterns. You're inventing new ones that will define how humans and AI collaborate.

- Massive Scale Potential: Early product-market fit signals with explosive organic growth. Your work will impact millions of daily conversations.

- Technical Innovation: Implementing AI capabilities that don't exist anywhere else, group preference learning, multi-participant coordination, social facilitation algorithms.

- Founding Impact: Direct influence on product direction, technical architecture, and company culture.

What You'll Build

Own the Mobile Platform (Primary Focus)

- Lead development of our React Native app from ground zero to millions of users

- Create seamless group collaboration experiences impossible on any other platform

- Build AI-native interfaces that feel magical, not mechanical

- Ship polished, performant experiences across iOS and Android
