About the role

We're looking for a Senior Product Engineer who thrives at the intersection of product and engineering.
Serving as a "player-coach," you will act as the engineering counterpart to product management to help with technical roadmapping and sprint execution.

Partner directly with product leadership on architectural decisions, sprint planning and technical execution.
Ship focused, user-facing applications and developer tooling end-to-end, owning frontend, backend, and workflow design.
Design and build complex workflows around generative models: chained and parallel generation calls, long-running async operations, streaming results, caching, retries, and graceful degradation around inference that takes seconds to minutes.
Own the deliverable: you set and hold the quality bar for what ships under your name - correctness, performance, polish, and maintainability - and you review others' work to the same standard.
Work directly with users and design partners
A product-minded approach: you form opinions about what users need, validate them cheaply, and change course on evidence.
We're building something bigger than any one person.

6+ years of software engineering experience (8+ for Staff), with a track record of end-to-end ownership.
Deep proficiency in modern web application technologies for the frontend (e.g., TypeScript, React) and backend services, with a strong understanding of web architecture
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.

While not required, experience in one or more of the following is a strong plus:
Experience in 3D graphics programming and shader development, particularly web frameworks such as WebGL and three.js.
Fearless Innovator: We need people who thrive on challenges and aren't afraid to tackle the impossible.
Resilient Builder: Impacting Large World Models isn't a sprint
it's a marathon with hurdles.
Mission-Driven Mindset: Everything we do is in service of creating the best spatially intelligent AI systems, and using them to empower people.
We need team players who can harness the power of collective intelligence.
We're hiring the brightest minds from around the globe to bring diverse perspectives to our cutting-edge work.
