Job summary

Kelvin Quantum, a semiconductor startup spun out of the University of Glasgow, seeks a Mixed-signal & analog/RF ASIC designer to own analogue, RF and mixed-signal blocks from spec to silicon. You will lead verification, bring-up and integration with cryogenic testing, improving control/readout for quantum hardware.

The role offers on-site Glasgow, with a clear path to technical leadership as the team grows, and a bonus-driven, growth-focused environment.

Qualifications

• Degree in Electrical/Electronic Engineering, Physics, Microelectronics or related field.
• 3+ years' professional experience in analogue, RF or mixed-signal CMOS IC design.
• Production experience with Cadence Virtuoso, Spectre and ADE, and a full ASIC flow: DRC/LVS, parasitic extraction, post-layout simulation (Calibre or PVS/QRC).
• A real design portfolio in data converters, low-noise amplifiers, RF mixers, RF synthesisers, bandgap/biasing, high-speed multiplexers.
• Working knowledge of CMOS device physics, noise analysis, mismatch and layout-dependent effects.
• At least two ASICs taken through tape-out and bring-up.
• Good written and verbal communication.
• Right to work in the UK.

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 solid-state qubits.
• Run full design verification: schematic, pre- and post-layout simulation.
• Work with 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.
