Job description

Overview

Your Role 1QBit is looking for an analog / mixed-signal integrated circuit (IC) designer to join our growing R&D team, a division of the company that works on advancing emerging computational technologies, including quantum computing. You will join a team of talented scientists and software developers who tackle uniquely challenging problems in their quest to develop new computational paradigms. You will use your skills as an IC designer to develop superconducting circuit designs. Your responsibilities will include designing custom mixed-signal superconducting low-power, low-noise, high-speed circuits, and you will have ample opportunities to share your expertise and receive guidance from and learn from your peers.

What You'll Do

• Work closely with fellow scientists to codesign algorithms and their hardware implementations
• Bring a design from the concept stage through to modelling, layout, and verification
• Engage in tasks that involve schematic capture, circuit simulation, circuit layout, physical verification (LVS, DRC), and parasitic extraction for a variety of superconducting circuits
• Teach and guide your peers on topics related to circuit design, superconductivity, and single-flux quantum technology

What You'll Bring

• A PhD, or equivalent experience in electrical engineering or physics
• Demonstrated experience in the development and design of custom circuits in Cadence Virtuoso or similar environments
• Experience with modelling, such as Ansys Q3D Extractor, FastHenry, or InductEx, and characterizing circuit performance with the help of circuit SPICE-like and EM simulators such as COMSOL Multiphysics, Sonnet Suites, or Ansys HFSS
• Outstanding communication, organization, and leadership skills
• The ability to convey rigorous technical concepts and considerations to non-experts
• An eagerness to learn about new trends, tools, and technologies, and to continually consider how these will influence our projects and the resulting implications and opportunities that they will bring

Nice to Have

• Familiarity with superconducting quantum devices
• Experience in the design and testing of superconducting electronics circuits and the characterization of cryogenic electronics
• Experience with PDK-based circuit design
• Experience with ASIC workflows, that is, with logic synthesis, RTL design, and related toolkits such as Genus Synthesis or RTL Architect
• Programming experience in a high-level programming language like Python or C++
