Mixed-signal & analog/RF ASIC designer

Job Description

About us

Kelvin Quantum is a semiconductor company spun out of the University of Glasgow. We develop hardware that runs continuously from room temperature down to deep cryogenic environments, near absolute zero — from individual integrated circuits to fully integrated control and readout systems for next-generation quantum technologies. Our technology lets quantum hardware teams build scalable, more powerful machines with real-world impact.

The role

You will design low-power, low-noise integrated circuits — DACs, ADCs, LNAs, RF mixers, PLLs, multiplexers, power supplies and bias networks — that must work reliably at cryogenic temperatures. Every block is yours from architecture and specification through schematic, layout supervision and tape-out, to characterisation in our cryogenic lab. It is a hands-on role with a clear route into technical leadership as we grow.

What you’ll do

• 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 solid-state qubits
• Run full design verification: schematic, pre- and post-layout simulation
• Work with our packaging, PCB, FPGA and quantum applications teams to integrate ASICs into cryostat subsystems
• Support tape-out, characterise silicon at room and cryogenic temperatures, and write the technical documentation that goes with it
• Mentor junior engineers and help shape how the IC team works as we grow
