Job summary

QuantWare is seeking a Junior Quantum Design Engineer to design and lay out superconducting circuit components and test structures, including resonators, qubits, and control lines. You will perform EM simulations, verify layouts against fabrication constraints, and iterate designs based on measurement data.

You’ll contribute to design tooling, automation scripts, and documentation, collaborating with cross‑functional R&D teams to scale quantum processors and push the boundaries of QPU technology.

Qualifications

• Experience with microwave engineering, circuit theory, or superconducting devices through coursework, thesis or internship.
• 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.

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.
