Job summary

QuantWare is seeking a Junior Quantum Design Engineer to design and layout superconducting circuit components, such as resonators and qubits, while driving simulations and verification with R&D colleagues. You’ll help translate concepts into production‑ready designs and iteratively improve models with measurement data.

You’ll collaborate across fabrication, measurement, and system integration teams in a fast‑moving environment, using Python, EM tools, and layout software to push toward scalable

Qualifications

• MSc in Physics, Applied Physics, Electrical Engineering or related, ideally with Quantum Computing focus (PhD a plus).
• Understanding of microwave engineering, circuit theory, or superconducting devices from coursework/thesis/internship.
• Experience with EM simulation tools (HFSS, Q3D, Sonnet) and layout tools (KLayout, Qiskit Metal).
• Python skills for design automation, simulation workflows, or data analysis.
• Detail‑oriented mindset with structured design, verification, and documentation.
• Eagerness to learn, take ownership, grow in a multidisciplinary team.
• Familiarity with superconducting qubits, circuit quantisation, or cleanroom fabrication 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.
