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 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. Serving as a "player-coach," you will act as the engineering counterpart to product management to help with technical road mapping and sprint execution.

You will bring crucial software engineering and technical leadership experience to support a highly talented product team that currently leans heavily on design.

• Partner directly with product leadership on technical road mapping, sprint planning, and execution.
• Serve as a Technical Lead and mentor (player-coach) to support a cross-functional product team.
• Contribute technically as a full-stack engineer to both the frontend and backend of our core web applications.
• Develop and ship user-facing features with a highly product-minded approach, moving beyond just building internal tools or libraries.

• 4-10 years of software engineering experience, demonstrating adaptability and ownership.
• Deep proficiency in modern web application technologies for the frontend (e.g., Type Script, React) and backend services, with a strong understanding of web architecture; especially in interactive and real-time applications with performance considerations.
• Proven experience serving in a Tech Lead or senior mentorship capacity for engineering and design teams.
• A highly product-minded approach with a strong drive to design end-to-end systems and ship features.
• Excellent problem-solving abilities and a strong foundation in computer science principles.

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.
• Experience building applications around generative image, video, or 3D AI models.
• Contributions to open-source graphics or machine learning projects.
• Experience working in VFX, gaming, 3D design, or other industries that focus on high-fidelity visual outputs.

• 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.

We re hiring the brightest minds from around the globe to bring diverse perspectives to our cutting-edge work. If you re ready to work on technology that will reshape how machines perceive and interact with the world, World Labs is your launchpad.
