About World Labs

World Labs is a spatial intelligence company, building frontier models that can perceive, generate, and interact with the 3D world. Backed by NEA and a16z.

About the role

We’re looking for a Senior Product Engineer who thrives at the intersection of product and engineering. You should have strong coding skills across the stack, a deep appreciation for intuitive user experiences, and the technical expertise to design end-to-end systems. In this role, you’ll own product features end-to-end—from ideation through to building responsive, user-centric web apps and backend services.

What they're looking for

  • 6+ years of software engineering experience (8+ for Staff), with a track record of end-to-end ownership. You've shipped user-facing products, not just components of them, and you've been accountable for their quality in production
  • Deep proficiency in modern web application technologies for the frontend (e.g., TypeScript, React) and backend services, with a strong understanding of web architecture, especially in interactive and real-time applications with performance considerations
  • Fluency with AI-assisted development workflows, grounded in fundamentals strong enough to verify, correct, and own everything you ship — you use the tools to move faster, not to outsource judgment
  • Experience building products on top of asynchronous, long-latency, or streaming APIs
  • A product-minded approach: you form opinions about what users need, validate them cheaply, and change course on evidence
  • Excellent problem-solving abilities and a strong foundation in computer science principles
