We’re on a mission to redefine how people interact with the world around them. Our next-generation platform transforms maps into living, dynamic experiences — blending AI, real-time data, video, spatial interfaces, and intelligent agents to create a new way to discover, connect, and explore.

We’re tackling one of the most used product categories on the planet with a vision to make it smarter, more personal, and infinitely engaging. Backed by top-tier investors and led by proven founders who’ve scaled massive consumer platforms, we’re building a team to take on bold technical challenges — and we want you at the ground floor.

The Opportunity

As a Founding Engineer, you’ll have true end-to-end ownership of systems and features that define our product. This is not a narrow role — you’ll work across mobile, web, backend, and data infrastructure, shaping the technology, architecture, and culture from day one.

Depending on your strengths, your focus might lean toward

Full Stack Application Engineering ,

Backend/Data Systems , or a hybrid of both — but you should thrive in wearing multiple hats and working outside your comfort zone.

What You’ll Do

Architect & Build : Develop core features across mobile, web, and backend systems with a relentless focus on performance, scalability, and user delight.

Innovate in Mapping : Design and implement cutting-edge, interactive, map-based experiences for millions of users.

Integrate Intelligence : Power AI-driven features, intelligent agents, and real-time systems to make our maps dynamic and context-aware.

Own the Stack : From backend services and APIs to data pipelines and distributed architectures, take full responsibility for delivering end-to-end solutions.

Shape the Culture : Define best practices, processes, and technical direction for a high-performing engineering team.

Ship Fast : Move from idea to launch with speed, autonomy, and creativity.
