In this measurement-based architecture, qubit readout is especially vital. Come join the multidisciplinary team building a scalable readout system for topological quantum computing!

We're looking for a  
** Senior**  /  
** Principal Process Design Kit (PDK) Engineer;
** in this pivotal role you will help develop and mature a cryogenic process-design-kit for superconducting quantum hardware. You will own the model-to-measurement characterization loop for cryogenic devices and process primitives. You will partner with foundry, device, and hardware teams to extend foundry PDK capability to cryogenic temperatures, plan and analyze cryogenic characterization test chips, and translate measurement results into accurate models, design rules, and process guidance.

This opportunity will allow you to shape foundational design infrastructure for quantum hardware while working on fast-paced and interdisciplinary teams.

Microsoft's mission is to empower every person and every organization on the planet to achieve more. As employees we come together with a growth mindset, innovate to empower others, and collaborate to realize our shared goals. Each day we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond. 

** Responsibilities*
* + Own the model-to-measurement characterization loop for cryogenic process primitives, including test definition, measurement planning, data analysis, parameter extraction, and model update workflows.

+ Develop, maintain, and refine cryogenic PDK requirements for superconducting circuit technologies, with emphasis on accurate low-temperature device models, parameter extraction, and design-rule coverage.

+ Partner with external foundries and internal teams to extend foundry PDKs from room-temperature or nominal process assumptions to cryogenic operating regimes relevant to quantum hardware.

+ Plan, design, and analyze cryogenic characterization test chips for key primitives.

+ Partner with foundry, device, packaging, and quantum-hardware design teams to connect fabrication process capability, measured cryogenic performance, and scalable circuit-design requirements.

+ Establish robust characterization infrastructure, including design-of-experiments methods, test structures, data pipelines, statistical summaries, and documentation that enable repeatable PDK updates.

+ Use industry-standard electronic-design-automation, layout, and physical-verification toolsets to support superconducting circuit design, test-chip development, and PDK validation.

+ Embody our Culture ((Use the "Apply for this Job" box below).)  and Values () .
