We’re building the future of maps — reimagining them as platforms for discovery, personalization, connection, and real-time exploration. Imagine crafting rich experiences powered by AI, real-time data, video, spatial UI, and intelligent agents — this is your moment to help build a product that everyone you know can use and love.

We’re assembling a world-class team to solve some of the hardest and most exciting technical challenges out there — and we want you on board.

Requirements

Who We’re Looking For

As a Founding Engineer, you’ll have ownership over the core features and systems that define our product. You’ll work end-to-end — from concept to deployment — across web, mobile, backend, and data infrastructure.

You might focus more on Application (Full-stack) engineering, Backend/Data systems, or a blend of both, but you’re excited to wear multiple hats.

Full-stack / Application Engineering

You’ll design and build cutting-edge, map-based user experiences for mobile and web.

You should have experience with:

  • TypeScript and React (web)
  • and/or Swift (iOS), Kotlin / Java (Android)
  • Building delightful, performant UIs
  • Working across the stack in a TypeScript backend environment to deliver complete features

Backend & Data Engineering

You’ll power the intelligence behind our product — from search to real-time pipelines to AI-driven agents.

You should have experience with:

  • Python and/or TypeScript
  • Data pipelines, backend systems, and distributed architectures
  • Building AI-powered agents or integrating with LLMs
  • Handling large-scale data and high-throughput systems
  • Bonus: Experience with Elasticsearch or similar search technologies

Why Join Us

  • Massive Impact: We’re tackling one of the most widely used product categories in the world, with the goal of redefining how people connect with each other and the world around them.
  • Elite Support: Backed by top-tier investors and seasoned operators who have built category-defining products.
  • Proven Founders: Leadership with a track record of scaling massive consumer platforms.
  • Culture of Creativity: Everyone ships. Ideas flow freely, and the best ones go live fast.
  • In-person, high-energy environment: We believe speed and creativity come from being in the same room.
  • World-class team & vibes: Work with exceptional people who are both brilliant and humble.

The Role

  • Build core product features that millions will use daily
  • Work on complex, high-impact problems from concept to launch — whether it’s a real-time mapping layer, intelligent agent systems, or distributed search infrastructure
  • Collaborate directly with founders on product direction and technical architecture
  • Shape the engineering culture, processes, and technology stack from day one
  • Thrive in a fast-paced, hands-on environment where ownership is the default
