Job summary

QuantWare in Delft is seeking a Junior Quantum Design Engineer to join the R&D hardware team on a full-time basis. You will design superconducting circuits and run simulations in a fast-moving, collaborative environment.

From day one you’ll work with world-class experts, access advanced tools, and contribute to design verification, with a strong emphasis on learning and growth in quantum technology.

Qualifications

• MSc in Physics, Applied Physics, Electrical Engineering or related field, ideally with a concentration in Quantum Computing or Quantum Technology (PhD is a plus).
• Understanding of microwave engineering, circuit theory, or superconducting devices, gained through coursework, a thesis project, or an internship.
• Experience with EM simulation tools (e.g. HFSS, Q3D, Sonnet) and layout tools (e.g. KLayout, Qiskit Metal).
• Python skills for design automation, simulation workflows, or data analysis.
• Detail-oriented mindset with a structured approach to design, verification, and documentation.
• Eagerness to learn, take ownership, and grow within a fast-moving, multidisciplinary team.
• Familiarity with superconducting qubits, circuit quantisation, or cleanroom fabrication processes is a plus.

Responsibilities

• Design and lay out superconducting circuit components and test structures, such as resonators, qubits, and control lines.
• Perform electromagnetic and circuit simulations to predict device parameters and optimise designs.
• Contribute to design verification, including design-rule checks and review of layouts against fabrication process constraints.
• Compare simulation results with measurement data to validate design models and feed learnings back into future design iterations.
• Help develop and maintain design tooling, automated layout scripts, and documentation to make our design flow faster and more robust.
