ASIC Designer for Cryo-CMOS

Job Description

About Kelvin Quantum
Kelvin Quantum is a Glasgow-based semiconductor company spun out of the University of Glasgow. We develop advanced hardware solutions capable of continuous operation from room temperature to deep cryogenic environments, near absolute zero. Our portfolio ranges from individual integrated circuits to fully integrated electronic systems for quantum control and readout, tailored to meet the requirements of next generation quantum technologies.

Our technologies let quantum hardware teams build scalable, more powerful machines with real-world impact.

The Role
As an ASIC Designer for Cryo-CMOS, you will design low-power, low-noise integrated circuits (DACs, ADCs, LNAs, RF mixers, PLLs, multiplexers, power supplies, and bias networks) that must operate reliably at cryogenic temperatures. You’ll own circuits end-to-end: architecture, specification, schematic, layout supervision, tape-out, and characterisation in our cryogenic lab.

It is a hands-on role with a clear route into technical leadership as we grow.

Key responsibilities

• Take analogue, mixed-signal and RF CMOS blocks from specification to silicon, schematic, layout supervision, tape-out, and bring-up.
• Design low-noise, low-power circuits for the control and readout of various types of solid-state qubits.
• Perform full design verification: schematic, pre- and post-layout simulations.
• Collaborate with our packaging, PCB, FPGA, and quantum applications teams to integrate ASICs into cryostat subsystems.
• Support tape-out, contribute to silicon characterisation at room and cryogenic temperatures, and prepare technical documentation.
• Mentor more junior engineers and help shape how the IC team works as we grow.
