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 a Quantum 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.
