Software Engineer, Backend

Fab2 • San Francisco, CA

5d • Onsite

About The Position

The fab2 team builds the product that runs their entire fab—a central web app used to manufacture chips. Their users are internal process engineers. They build tools for managing hardware, monitoring and controlling systems in real time, designing processes, and analyzing experimental data. The work on this team spans frontend, backend, and data, all focused on making the fab programmable, observable, and easy to operate as they push toward a fully software-defined chip manufacturing process driven by AI and ML orchestration. They are looking for a Senior Backend Software Engineer to build the core systems that power their fab product. This role will focus on backend architecture, data models, and bridging the gap between their central web applications and physical manufacturing hardware. Success will be measured by process engineers being able to seamlessly and reliably control, monitor, and orchestrate fab hardware in real-time through the systems architected.

• Experience running a homelab or building infrastructure for fun.

Responsibilities

• Lead the architecture and development of high-performance backend APIs (Go, Rust, gRPC) that power our central fab product.
• Break down complex manufacturing challenges into actionable data models (recipes, runs, tools, wafers, jobs) and technical plans for yourself and the broader team.
• Integrate web applications with underlying hardware and embedded systems, ensuring seamless, real-time operations.
• Ensure the reliability, observability, and performance of mission-critical manufacturing systems, holding yourself and the team accountable to clear timelines.
• Drive the long-term system architecture, challenging existing assumptions to support our evolving fab processes and yield optimization goals.
