# Scientific Software Engineer

About the Mission Every chip Alice & Bob builds starts as Python code. As we scale from tens of qubits to thousands, our chip-design software becomes the backbone of the entire design pipeline, and it has to support chips that could never be drawn by hand. About the Role As a Scientific Software Engineer in the Design and Implementation team, you’ll own the internal framework our engineers use to turn a quantum circuit into a layout and send it to electromagnetic and circuit simulators. You’ll keep it robust and fast, grow its component library, and build the automation our layout and scale-up engineers need to design large chips. Responsibilities Own and maintain the internal design backend API and qubit design framework: code quality, testing, CI, releases, documentation Develop new parametric components and layout primitives with the chip designers who use them Extend and harden the export pipeline to electromagnetic and circuit simulation tools Build the automation layer for large-scale, hierarchical chip layouts in close partnership with our physical-design and scale-up engineers Support internal users: onboarding, debugging, API design, and turning recurring pain points into
