Cryo RFIC Design Engineer, Quantum

Job Title

Cryo RFIC Design Engineer, Quantum

Role Summary

Design and deliver high-performance RF and microwave integrated circuits and reusable IP for advanced semiconductor applications, with emphasis on cryogenic CMOS and quantum systems. The role covers architecture, transistor-level design, electromagnetic-aware layout, tapeout, and silicon characterization while collaborating with device modeling, PDK, packaging, and test teams.

Experience Level

Senior-level. Minimum 5 years of relevant RF/microwave or analog IC design experience (job specifies a Senior RF IC Design Engineer).

Responsibilities

The engineer will own RFIC development through all phases and support silicon bring-up and characterization.

• Design RF/microwave ICs and reusable IP: LNAs, PAs, mixers, oscillators, VCOs, frequency synthesizers, RF switches, phase shifters, matching networks.
• Lead schematic-level design, simulation, EM-aware layout, DRC/LVS, parasitic extraction, tapeout, and silicon validation.
• Perform RF circuit analysis across process, voltage, and temperature: S-parameters, noise figure, gain, linearity, stability, phase noise, power, and impedance matching.
• Drive electromagnetic simulation and modeling of passives, interconnects, transmission lines, inductors, transformers, and critical layout structures.
• Optimize circuits for power, bandwidth, noise, linearity, area, process variation, package/interconnect parasitics, and cryogenic performance.
• Define silicon test structures, develop characterization plans, analyze measured data, and correlate results with simulations.
• Lead technical design reviews, document methodology and results, and mentor other engineers.
• Collaborate cross-functionally with technology, PDK, modeling, packaging, and test teams to improve design enablement.
• Perform work in compliance with Environmental, Health, Safety & Security requirements.

Requirements

Must-have technical skills and experience required for successful performance in the role.

Must-have:

• Minimum 5 years of RF, microwave, or analog integrated circuit design experience.
• Proven experience taking RF/microwave ICs through schematic design, simulation, layout, DRC/LVS, parasitic extraction, tapeout, and silicon validation.
• Strong knowledge of RF fundamentals: impedance matching, S-parameters, stability, noise, linearity, phase noise, RF power, passive networks, and transmission-line effects.
• Proficiency with RFIC design tools: circuit simulation, EM simulation, layout, physical verification, and post-layout extraction workflows.
• Experience with RF measurement and test equipment (VNA, spectrum analyzer, signal generators, noise-figure measurement, RF probing).
• Willingness to travel up to 10% and fluency in written and verbal English.

Nice-to-have:

• Experience with cryogenic RFICs, quantum readout/control electronics, millimeter-wave circuits, or advanced RF front ends.
• Familiarity with CMOS device and passive-component behavior and compact-model limitations at RF/cryogenic conditions.
• Experience with on-wafer RF characterization and correlating measured results to circuit, device, EM, and package models.
• Scripting/automation experience using Python, SKILL, Tcl, MATLAB, or equivalent.
• Experience designing advanced RF blocks: LNAs, PAs, mixers, VCOs, PLLs, RF switches, phase shifters, and integrated matching networks.
• Project management and strong communication, planning, and organizational skills.

Education Requirements

Required: Bachelor’s degree in Electrical Engineering, Microelectronics, Applied Physics, or a related field. Preferred: Master’s degree or PhD in Electrical Engineering, Microelectronics, RF/Microwave Engineering, or a related field. (Degrees and fields explicitly listed in the posting.)
