Quantum System Architect - Software

Qblox is a deep-tech scaleup whose mission is to accelerate the worldwide race towards scalable quantum computers. We do this by providing some of the world's most advanced quantum control stacks to a large range of customers across the globe.

Our hardware and software sit right next to the quantum chips, giving experimentalists precise control and readout of their qubits. Through our open-source interfaces qblox-scheduler and qblox-instruments, users can write and execute experiments and algorithms using Python – from defining quantum circuits to compiling down to our quantum assembly, Q1ASM.

We offer a dynamic environment where engineering meets cutting-edge physics research.

We need a Software Architect who understands the full stack – from FPGA firmware through embedded systems to high-level C++ and Python APIs – and can design the architecture that ties it all together.

You'll own the technical vision for how our control stack scales from 100+ to 1,000+ qubits and beyond. This means understanding constraints at every layer: what the FPGAs can do, how firmware schedules instructions with nanosecond precision, how the compiler can optimize quantum circuits, and how users interact with all of it through clean Python interfaces.

In this role, you will balance broad strategic vision with tactical technical depth. We need an architect who can design sophisticated, high-level abstractions while understanding the physical constraints of the hardware. 

You empower teams by providing the architectural guardrails and technical clarity they need to move fast. You measure your success by how much more effective the engineers around you become. 

Note: a physics or quantum computing background is nice to have, but not required.
