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
