Seniority
Employer Type
Alice & Bob is developing universal, fault-tolerant quantum computers based on new superconducting qubits. The Senior Process Integration Engineer will join the Foundries & Process Integration team. This role involves modeling how material properties, process parameters, and variations impact superconducting qubit behavior. The engineer will guide process development, support test structure design, and contribute to improving chip performance, yield, and reliability.
Key Responsibilities
Develop and maintain models of nanofabrication processes and link them to device performance metrics (Qi, T1, inductance uniformity, etc.).
Model the impact of process variations (thickness, linewidth, resistivity, junction parameters, etc.) on device and circuit performance, performing tolerance and sensitivity analyses.
Collaborate with design team to define and validate new test structures that benchmark process stability and device behavior.
Model superconducting material properties and associated loss channels and propose methods to mitigate them.
Analyze experimental and characterization data to refine and validate models (SPC, DOE, regression, machine learning approaches).
Propose and support process improvement plans based on modeling-driven insights.
Support technology transfer to and from external foundries, ensuring design and process compatibility through predictive modeling.
Required Skills
Master’s degree or Ph.D. in Physics, Electrical Engineering, Materials Science
5+ years of experience of process and device modeling preferably in the field of superconducting circuits
Strong background in semiconductor/superconductor device modeling and process variation analysis
Knowledge of superconducting materials and devices, including loss mechanisms (dielectric loss, interface loss, quasiparticles)
Proficiency with simulation, modeling and design tools (e.g., COMSOL, Ansys EDT, Python and Klayout for custom modeling)
Experience designing and analyzing loss test structures (CPW resonators, junction test devices)
Strong analytical and problem-solving skills with attention to detail
Nice-to-have Skills
Familiarity with statistical and data-driven approaches (SPC, DOE, machine learning) is a strong plus
