Senior Product Engineer San Francisco

We build foundational world models that can perceive, generate, reason, and interact with the 3D world — unlocking AI's full potential through spatial intelligence by transforming seeing into doing, perceiving into reasoning, and imagining into creating.

We believe spatial intelligence will unlock new forms of storytelling, creativity, design, simulation, and immersive experiences across both virtual and physical worlds.

We bring together a world‑class team, united by a shared curiosity, passion, and deep backgrounds in technology — from AI research to systems engineering to product design — creating a tight feedback loop between our cutting‑edge research and products that empower our users.

We’re looking for a Senior Full Stack 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 build complex 3D web applications. In this role, you’ll own product features end‑to‑end—from ideation through to building responsive, user‑centric web apps and backend generative AI services and APIs.

You’ll also collaborate closely with our research team to bring cutting‑edge AI research to life in real‑world applications. All in all, you’re a player coach as a strong engineer who is passionate to drive product development.

• Work as a Sr. Product Engineer to develop and ship products with a user‑centric approach.
• Develop and optimize web‑based 3D graphics tools and applications.
• Participate in all phases of the software development lifecycle, from design to deployment, including working directly with early testers and design partners to solicit user feedback.

• Strong track record in developing and shipping successful products.
• 6+ years of engineering experience and proven ability to operate effectively in startup environments as an early‑stage engineer or founder, demonstrating adaptability and ownership.
• Experience in building user‑focused web applications.
• Proficiency in modern web application technologies for frontend (e.g. Type Script, React, Node.js) and backend services, and a strong understanding of web architecture.
• Experience and strong curiosity in working with AI tools.
• Excellent problem‑solving abilities and a strong foundation in computer science principles.
• Strong communication and collaboration skills, with a focus on delivering high‑quality, impactful solutions.

• Experience in 3D graphics programming and shader development, particularly web frameworks such as WebGL and three.js. Experience building applications around generative image, video, or 3D models is particularly valuable.
• Experience working with generative AI, machine learning, neural rendering, etc.
• Contributions to open‑source graphics or machine learning projects.
• Experience building real‑time collaborative tools and applications.
• Experience working in VFX, gaming, 3D design, or other industries that focus on high‑fidelity visual outputs.

• Player coach:
  We are looking for strong product engineers who have played pivotal roles in successful product development and launch cycles.
• 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. We're looking for builders who can weather the storms of groundbreaking research and come out stronger.
• Mission‑Driven Mindset:
  Everything we do is in service of creating the best spatially intelligent AI systems, and using them to empower people.
• Collaborative Spirit:
  We're building something bigger than any one person. We need team players who can harness the power of collective intelligence.
