Full Stack Engineer San Francisco - Navier AI : Job Details

Navier AI is building the next generation of engineering design and analysis tools. Engineering software is stuck in the past, built on legacy codebases that hinder modernization, lack GPU-native code, and are complex to work with. Navier AI is building a modern engineering software stack from the ground up. We're developing software to empower hardware engineers to build the next generation of high-performance aircraft, cars, and electronics.

The Role: Full Stack Engineer

As a Full Stack Engineer on our founding team, you'll touch all parts of our tech stack. Our platform is built with a TypeScript frontend and a Python backend. We use modern libraries such as React, Three.js, and Zustand for our frontend, and FastAPI, Pyvista, Pydantic, and Polars in our backend.

What We're Looking For:

• Strong proficiency in Python and TypeScript / React
• Experience building and maintaining full stack applications in production
• Familiarity with cloud platforms like AWS, GCP, or Azure
• Solid understanding of frontend and backend development patterns
• Experience working on B2B SaaS platforms, ideally with multi-tenant architectures
• Comfortable with Git, CI/CD workflows, and modern development best practices
• Fast learner with a bias toward action and a willingness to dive into new technologies

Bonus:

• Experience with Three.js
• Experience in DevOps or cloud automation tools (Pulumi, Kubernetes, etc.)
• Familiarity with machine learning workflows and scientific computing
• Knowledge of containerization (Docker) and CI/CD pipelines

Why This Role is Special:

• Big Impact: You'll be part of a small, fast-paced team where your contributions will directly influence both the product and the company's direction. Every decision you make will have a meaningful impact.
• Variety & Ownership: You'll work across the entire tech stack—Python scripting, cloud architecture, and web development. There's no single problem, technology, or challenge that will define your work; you'll own the whole solution.
• Room for Growth: You'll have the opportunity to grow with the company, gaining exposure not only to cutting-edge technology but also to how startups are run and scaled.
• Close Collaboration: You'll work directly with the founders and a tight-knit team that's passionate about solving tough engineering problems.
