Quantum Design Engineer

About Us

QuantWare is the worlds leading manufacturer of superconducting quantum hardware. As a high growth start-up with a global customer base our mission is to accelerate the advent of the quantum computer. We push the boundaries of whats possible in our field. We work on making the worlds largest quantum processors as fast as possible.

At QuantWare were not just producing quantum hardware for the hyperscalers of tomorrow; were working on technology that will change the world. To make that ambition a reality we need exceptional people who drive real impact. Thats where you come in.

As a Quantum Design Engineer in our R&D team youll be at the heart of advancing the performance and scalability of superconducting quantum processors. Youll lead the design of next-generation qubit chips and modular scalable QPU architecture working from on-chip subsystem architecture to EM simulations frequency allocation crosstalk management packaging and interconnect strategies.

Youll also design and optimise nonreciprocal superconducting circuits such as isolators and parametric amplifiers that will drive robust high-fidelity readout chains. These designs will enhance readout signal-to-noise ratio and stability feeding into our next-gen readout modules and ensuring seamless coupling with the qubit layer.

This role is highly collaborative: youll work in a tight feedback loop with experimentalists and device engineers to transform measurement insights into rapid design iterations pushing performance coherence yield and manufacturability across the full qubit stack.

What youll be doing

• Design and simulate cutting-edge quantum hardware to improve performance coherence and scalability.

• Develop high-performance manufacturable device architectures that accelerate R&D cycles and increase qubit fidelity and yield.

• Architect and optimize the layout of nonreciprocal superconducting circuits such as parametric amplifiers targeting robust performance under cryogenic conditions.

• Interpret simulation results and correlate with experimental data to guide iterative design improvements.

• Collaborate across teams to ensure rapid design-to-test cycles connecting theory with experiment.

• Automate the design pipeline using Python enabling parametric device generation simulation sweeps and data post-processing.

Your profile

• MSc in Physics Electrical Engineering or related field with 2 years of industry experience or a PhD with relevant hands-on work

• Strong Python skills for automating designs controlling simulations and analyzing data

• Experience with EM simulation and chip design tools (e.g. Ansys HFSS-Q3D KLayout); Git and Qiskit-Metal familiarity is a plus

• Knowledge of cQED devices and superconducting circuit design is a strong advantage

• Experience designing nonreciprocal superconducting circuits (e.g. parametric amplifiers) or advanced readout techniques is highly valued

• Solid grasp of microwave engineering quantum noise sources and fabrication methods
