Rust Software Engineering Intern - Fall

Atomic Semi • San Francisco, CA

1d • $110,000 - $132,000 • Onsite

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. We are seeking Rust Software Engineering Interns for the fall term. The internship begins in September, with a preferred commitment of 4 to 8 months. You will 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 deeply 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. Our philosophy is to get things built and tested in days or weeks, not months. Because of this, a portfolio (can be your GitHub) is required to apply : show us the things you’ve actually built! For us, a good portfolio includes evidence of software engineering excellence and curiosity.

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

• 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
• Paid Time Off inclusive of Holidays and Sick Time
• Visa Sponsorship
• Medical, Dental, and Vision insurance
• 401(k) retirement plan
