QuantWare is the world's leading manufacturer of superconducting quantum hardware. As a hyper-growth scale-up with a global customer base, our mission is to accelerate the advent of the quantum computer. We push the boundaries of what's possible in our field. We work on making the world’s largest quantum processors as fast as possible.
At QuantWare, we’re not just producing quantum hardware for the hyperscalers of tomorrow; we’re working on technology that will change the world. To make that ambition a reality, we need exceptional people who drive real impact. That’s where you come in.
As a Quantum Design Engineer in our R&D team, you’ll be at the heart of advancing the performance and scalability of superconducting quantum processors. You’ll 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.
You’ll 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: you’ll 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 you’ll be doingDesign 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.
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
At QuantWare, you’ll be part of a high-performing team of world-class experts in an ambitious, fast-moving environment. From day one, you’ll have the trust, tools, and support to do your best work. Here’s what you can expect:
Competitive salary - A competitive monthly salary, plus an 8% annual holiday bonus paid out each May
Pension that’s built to last - A future-proof pension plan that includes partner and dependent coverage. QuantWare covers 63% of the premium
Flexibility built on trust - We focus on outcomes, not hours. You’re trusted to manage your time and energy responsibly, in a hybrid setup with an open vacation policy, because with freedom comes ownership
Relocation support - If you’re moving to the Netherlands, we’ll make the transition seamless. We cover visa support, temporary housing in most cases, and help securing the 30% tax benefit for eligible candidates.
Personal growth - We invest in your L&D, with a budget available to each team member, dependent on their individual ambitions, development needs, and performance
A focus on well-being - We support your physical and mental energy through wellness initiatives that help you recharge and stay sharp
A connected team - We make space to celebrate wins together, with team events, offsites, and spontaneous moments that bring us closer
Financial clarity - Through our partnership with Equip, you’ll get tools and expert guidance to help you understand and optimise your total compensation
Diversity & Inclusion at QuantWareAt QuantWare, we’re committed to building a diverse and inclusive team where everyone feels respected, valued, and empowered to contribute. We believe that varied perspectives drive better decisions, foster innovation, and strengthen our work.
If you’re excited about this opportunity but don’t meet every single requirement, we still encourage you to apply. You might bring a unique perspective or skill set that makes you a great fit for our team.
As part of our recruitment process, candidates may be required to undergo pre-employment screening.
