Software Engineer, Backend

**About fab2** The fab2 team can build anything. We design all the hardware and software needed to make chips and we make the fabs, tools, and components ourselves. We're looking for exceptional, hands\-on people who can iterate to the limits of what's possible. fab2 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** The Fab Software team builds the product that runs our entire fab—a central web app used to manufacture chips. Our users are internal process engineers. We 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 we push toward a fully software\-defined chip manufacturing process driven by AI and ML orchestration. **About the role** We are looking for a Senior Backend Software Engineer to build the core systems that power our fab product. You will focus on backend architecture, data models, and bridging the gap between our central web applications and physical manufacturing hardware. You will know you are successful when process engineers can seamlessly and reliably control, monitor, and orchestrate fab hardware in real\-time through the systems you’ve architected. **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 m
