Full Stack Engineer

About Navier AI

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.

Role Overview

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.

Responsibilities

Build interactive web applications using TypeScript, React, and Three.js to visualize CAD models, simulation results, and agent outputs

Develop backend services in Python to power workflows, handle model inference requests, and manage user data

Design intuitive UIs and workflows that make AI-powered engineering agents accessible and useful to domain experts

Implement real-time rendering and 3D visualization pipelines for CAD, meshes, and simulation outputs

Collaborate with ML and backend engineers to connect front-end tools with AI models and simulation infrastructure

Ensure application performance and scalability through robust state management, API design, and efficient data handling

Participate in architecture discussions and help define best practices for frontend + backend integration

Own features end-to-end, from design to deployment, in a fast-paced startup environment

Qualifications

Required

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)

Strong product intuition and ability to collaborate closely with designers and engineers

Bonus

Experience with CAD visualization, computational geometry, or simulation tools

Knowledge of WebGL or shader programming (GLSL, WGSL)

Experience integrating ML model inference into production apps

Familiarity with containerization (Docker) and cloud deployment (AWS, GCP, or Azure)

Prior work in engineering-focused or scientific software companies

Why This Role Matters

The interfaces you build will be the primary way engineers interact with Navier’s autonomous agents. You’ll shape how complex geometry, simulation results, and AI-driven design decisions are visualized and explored. Your work will directly impact the usability, adoption, and trustworthiness of a category-defining product.
