Backed by Y Combinator.
About the role
We’re hiring a Full Stack Engineer to build the interactive interfaces and backend services that power our autonomous engineering agents. You’ll be responsible for creating seamless user experiences that let engineers visualize complex geometry, interact with AI agents, and manage design workflows—all while collaborating closely with ML, backend, and simulation teams.
What they're looking for
- Strong proficiency in TypeScript and React
- Experience building 3D interactive experiences with Three.js or similar frameworks
- Solid backend development experience in Python (FastAPI, Flask, or Django preferred)
- Familiarity with API design, authentication, and data handling best practices
- Ability to work across the stack and own features from frontend to backend
- Comfort working with scientific/engineering data formats (e.g., meshes, STL, point clouds)
More about this role
Navier AI is building the first autonomous engineering agents. AI systems that can design, simulate, and optimize complex products to achieve breakthrough levels of performance. Our mission is to enable engineers to move beyond today’s slow, manual design cycles by providing agents that reason about physics, explore design trade-offs, and generate high-performance solutions across aerospace, automotive, and advanced manufacturing.
We’re backed by top-tier investors and work directly with industry leaders to deploy AI-native tools that go far beyond today’s design automation.
