OQC designs superconducting quantum processors and the control stack required to operate them at scale. The engineering-heavy hiring mix (14 of 18 active roles) skews senior, with active projects spanning hardware fabrication, control-software automation, and quantum-classical algorithm design — pointing toward a company building the full vertical stack rather than outsourcing critical components. Current pain points center on error reduction, test infrastructure, and use-case validation, typical operational challenges for a hardware-software platform still in early commercial deployment.
Oxford Quantum Circuits builds quantum computers and associated control software for enterprise customers. Founded in 2017 and based in Reading, UK, the company operates a 51–200-person team with core competency in superconducting qubit design, cryogenic systems, and embedded control electronics. The technology stack reflects full-stack quantum engineering: hardware design tools (Cadence, Synopsys, KLayout, Verilog, SystemVerilog) and compilers (LLVM, MLIR) alongside traditional infrastructure (NetSuite, Slack, Python). Current initiatives include high-fidelity experiments on superconducting circuits, test-stand design, and scoping enterprise use cases in hybrid quantum-classical workflows. Hiring is accelerating in the US, concentrated in senior and mid-level engineering roles.
OQC uses Cadence, Synopsys, LLVM, MLIR, Python, Verilog, SystemVerilog, VHDL, Rust, and C++ for quantum hardware and compiler design. Administrative tools include NetSuite, Slack, HiBob, and Workable. EDA and fabrication tools span KLayout, L-Edit, Altera Quartus, and electron-beam lithography.
OQC is running high-fidelity experiments on superconducting quantum circuits, building test infrastructure and control-software automation, designing hybrid quantum-classical algorithms, and scoping enterprise quantum use cases. Equipment design and accounts-payable process improvements are also underway.
