About the 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.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What we are looking for
- A degree in Electrical/Electronic Engineering, Physics, Microelectronics, or a related field.
- At least 3 years of professional experience in analog, RF, or mixed-signal CMOS IC design.
- Solid production experience with Cadence Virtuoso, Spectre, ADE, and a full ASIC flow including DRC/LVS, parasitic extraction, and post-layout simulation (Calibre or PVS/QRC).
- A real design portfolio in at least one of: data converters (DAC/ADC), low-noise amplifiers, RF mixers, RF synthesisers, band gap/biasing, or high-speed multiplexers.
- A working knowledge of CMOS device physics, noise analysis, mismatch, and layout-dependent effects.
- At least two ASIC successfully taken through tape-out and bring-up.
- Good written and verbal communication.
- Right to work in the UK.
Nice to have
None of these is required, but each is genuinely useful:
- Hands-on experience designing or measuring ICs at cryogenic temperatures.
- Familiarity with cryogenic device modelling or cryo-CMOS SPICE models.
- Experience with advanced CMOS nodes, 40 nm and below, 22/28 nm FDSOI.
- A background in IC design for quantum computing control and readout, or extreme environments.
- RF measurement and microwave packaging experience.
- Experience with cloud-based EDA flows (AWS or equivalent) and foundry MPW / shuttle logistics.
- Experience with Verilog / SystemVerilog to talk sensibly with the FPGA and digital teams.
- Track record of publications, patents, and/or shipped products.
Why Kelvin Quantum
At Kelvin Quantum, you will build a career with purpose while contributing to pioneering quantum technologies.
