OQC designs and fabricates superconducting quantum processors, with a stack that spans chip layout (KLayout, Cadence, HFSS), FPGA control firmware (Verilog, VHDL) and a compiler toolchain on LLVM and MLIR. Hiring is accelerating and engineering-heavy, with a senior skew. The work centres on moving quantum systems into commercial data centres and industrialising in-house fabrication.
Oxford Quantum Circuits (OQC) is a privately held UK company founded in 2017 that builds quantum computing hardware and software. Headquartered in Shinfield, Reading, it employs 51–200 people. Its work covers superconducting qubit design, cryogenics, control electronics and quantum software, including compilation and calibration. The company aims to deliver quantum systems suited to enterprise and data centre environments, and it is currently hiring in Spain.
OQC uses Python, C++, Rust, LLVM and MLIR for software, Verilog, SystemVerilog and VHDL for FPGA work, and HFSS, COMSOL, Cadence, KLayout and SolidWorks for hardware design. Kubernetes and Grafana support operations.
OQC is headquartered in Shinfield, Reading, in the United Kingdom. It was founded in 2017 and currently lists hiring activity in Spain.
Job posts point to end-to-end quantum computer deployment, logical compilation, high-fidelity single- and two-qubit operations, new superconducting processor designs and industrialising its fabrication capability.
