Job description

Senior Full Stack Engineer | 3D Visualization

Location: San Fransisco, CA | Hybrid

Compensation: $200,000–$250,000 Base + Equity

The Company

We're partnering with a well-funded, early-stage AI startup that spun out of Google X, The Moonshot Factory.

The company is building an ambitious AI-native platform that combines artificial intelligence, large-scale data, and interactive software to transform how complex real-world projects are planned, designed, and developed.

The Opportunity

We're looking for a strong Full Stack Engineer with some hands-on 3D development experience to help build the interactive experiences at the heart of the platform.

You'll work across the application, developing production-grade software that allows users to visualize, explore, and interact with complex 3D information.

You do not need to be a 3D specialist. The team is primarily looking for an excellent software engineer who has had some exposure to building interactive 3D functionality.

What You'll Do

• Design and build interactive, data-rich web applications.
• Develop 3D visualization features that allow users to explore and interact with complex geometry and spatial information.
• Own features end to end, from initial requirements and technical design through production deployment.
• Build across frontend and backend systems, contributing to architecture and performance.
• Work directly with product teams, designers, and domain experts to solve complex technical challenges.
• Help shape the technical direction of a growing platform.

What We're Looking For

• Professional software engineering experience, ideally building substantial web applications.
• Some hands-on experience developing interactive 3D functionality, whether professionally, academically, or through personal projects.
• Experience shipping production software and owning meaningful features end to end.
• Strong software engineering fundamentals, problem-solving ability, and product instincts.
• Comfortable working independently and collaborating within a small, fast-moving team.

Nice to Have

• Experience with Three.js, React Three Fiber, WebGL, Babylon.js, or similar technologies.
• Exposure to CAD, BIM, computer graphics, simulation, or complex geometry.
• Experience with geospatial data, mapping, or spatial visualization.
• Previous experience at an early-stage startup.

Interested?

If you're a product-minded Full Stack Engineer who enjoys building complex, interactive applications and has had some exposure to 3D development, we'd love to hear from you.
