Rust Software Engineering Intern - Summer

Atomic Semi • San Francisco, CA

80d • $110,000 - $132,000

About The Position

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.

Requirements

• Pursuing a BS in Computer Science, Computer Engineering, or demonstrated exceptional skill in software engineering
• Strong programming skills in Rust, or significant C++/systems programming experience and a strong desire to learn Rust quickly
• Solid understanding of systems fundamentals: memory, performance, concurrency
• Experience building non-trivial software projects from scratch (personal, academic, or professional)
• Interest in one or more of the following areas: real-time systems, computational geometry, algorithms, GPU programming, visualization

Nice To Haves

• Experience with interactive software such as Figma, Blender, CAD tools, KiCad, or scientific computing environments
• Background in compiling to WebAssembly or building rich applications
• Familiarity with schema evolution, database migrations, or serialization formats like Protobuf
• Understanding of collaborative or distributed systems (e.g., CRDTs, OT, WebSockets)
• Exposure to geometry or graph algorithms, optimization, or simulation (including spatial data structures and hierarchical representations)
• Experience with GPU programming and rendering technologies (WebGPU, Vulkan, OpenGL)
• Exposure to advanced 2D/3D visualization, simulation, or novel user interfaces

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

Benefits

• Housing Stipend to help with first month expenses
• Lunches daily, Dinners 3x per week, Stocked Office Kitchen with Snacks and Spindrifts
• Weekly Learning & Development opportunities
• Commuter Benefits including Parking and Late Night Uber rides from the office
