Rust Software Engineer

About Atomic Semi

Atomic Semi is building a small, fast semiconductor fab.

It's already possible to build this with today's technology and a few simplifications. We'll build the tools ourselves so we can quickly iterate and improve.

We're building a small team of exceptional, hands-on engineers to make this happen. Mechanical, electrical, hardware, computer, and process. We'll own the stack from atoms to architecture. Our team is optimistic about the future and we want to continue pushing the limits of technology.

Smaller is better. Faster is better. Building it ourselves is better.

We believe our team and lab can build anything. We've set up 3D printers, a wide array of microscopes, e-beam writers, general fabrication equipment - and whatever is missing, we'll just invent along the way.

Atomic was founded by Sam Zeloof and Jim Keller. Sam is best known for making chips in his garage, and Jim has been a leader in the semiconductor industry for the past 40 years.

About the team

At Atomic Semi, we're building a fast, small semiconductor fab from the ground up. The software team is responsible for everything that makes the fab run-writing the code that controls, manages, automates, and orchestrates the hardware that powers chipmaking.

About the role

We are seeking a Rust Software Engineer to help build the next generation of high-performance tools for chip fabrication and design. These tools blend real-time collaboration, computational geometry, GPU-accelerated visualization, simulation, interactive editing, and data processing.

This is a broad, multi-domain, hands-on role. You'll work across everything from low-level systems and data synchronization, to high-performance rendering, rich UI / UX editing tools, and distributed infrastructure. The software you build will help engineers design and understand real, physical systems. If you're excited by performance engineering, building complex features from scratch, and learning new domains quickly, this is a great place to grow.

A portfolio or GitHub is generally required to apply : show us the things you've built! For us, a good portfolio includes evidence of strong engineering skills and curiosity.

Responsibilities

• Build deeply interactive editing tools with low-latency, CAD- or Figma-like interfaces for geometry manipulation, routing, annotation, and measurement
• Develop production-grade Rust software targeting both native and WebAssembly environments
• Architect real-time collaborative systems, including state synchronization, conflict resolution, and efficient data transmission
• Implement efficient algorithms for geometry querying, graphs, and routing
• Build high-performance rendering and visualization pipelines, from GPU-accelerated rendering and spatial indexing to streaming massive datasets, visualizing millions of polygons, or rendering complex 3D fields
• Continuously profile and optimize CPU, GPU, memory, and network performance to push the limits of responsiveness and scale
• Own major features end-to-end and work closely with internal users, including process engineers and circuit designers, to deliver powerful, intuitive tools that solve real problems
