Quantum Design Engineer
Pubblicato il 18-09-2026 - Planckian in Pisa
Planckian is developing the core technology to power utility-scale quantum computers.
By design, our chip architecture decouples control lines from qubit count, removing a key bottleneck in scaling. It combines the proven reliability of superconducting circuits with a breakthrough approach to qubit control, paving the way for quantum computers capable of solving the world’s most challenging problems.
We are seeking aQuantum Design Engineer to support the design and optimization of superconducting qubits and quantum circuit architectures.
What You'll be doing
- Design superconducting qubits, couplers, and quantum circuits for scalable quantum processors
- Develop and optimize qubit architectures with respect to coherence, frequency crowding, control, and readout
- Perform electromagnetic and circuit-level simulations (participation ratios, loss channels, mode analysis)
- Analyze sensitivity to fabrication tolerances and process variations
- Define design rules that balance performance with manufacturability and yield
- Support the experimental team by interpreting measurement data and feeding results back into design iterations
- Contribute to system-level architectural choices (connectivity, coupling schemes, control simplification)
- Document designs, simulations, and design rationale for internal and external use
Requirements
- PhD or MSc in Physics, Applied Physics,
Electrical Engineering, or related field
- Proficiency with EM and circuit simulation tools (e.g., HFSS, Sonnet, COMSOL, or equivalent)
- Background in superconducting qubit physics and circuit quantum electrodynamics (cQED)
- Solid understanding of decoherence mechanisms and materials loss in superconducting devices
- Hands-on experience designing superconducting quantum circuits
- Ability to connect theoretical models with experimental constraints
Every job has its challenges, and this one is no exception. While many companies gloss over them, we believe in being upfront:
- You’ll face tough situations, especially the classic challenge: people problems. Navigating human dynamics can be tricky and requires patience and empathy.
- Some work is unglamorous, but building a great company means rolling up your sleeves. From strategic decisions to hands-on grunt work, everyone contributes to the heavy lifting.
We're not looking for perfection; we're looking for people who are ready to grow through the hard parts and help us build something that lasts.
What We Offer
- Competitive salary + benefits
- Stock options
- Flexible working hours with hybrid working
- Ego-free, merit-based environment
Planckian is an equal‑opportunity employer.
