Our full-stack approach spans innovations from the quantum plane to cryogenic control electronics, system architecture, firmware, software, and cloud services. As the complexity of our systems grows, understanding and predicting system behavior across the entire signal chain becomes increasingly critical. We are seeking a Principal Signal Integrity Simulation Engineer to lead the development of end-to-end simulation methodologies for next-generation quantum computing systems. This role sits at the intersection of signal integrity, RF engineering, cryogenic hardware, Cryo-CMOS electronics, packaging, and systems engineering.  The successful candidate will define how system-level models are developed, validated, and applied across the organization to reduce risk, accelerate development, and improve system performance. 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. ResponsibilitiesDefine and lead the end-to-end signal integrity simulation strategy for next-generation systems, spanning room-temperature electronics, cryogenic infrastructure, Cryo-CMOS subsystems, packaging, and quantum hardware. Develop and maintain system-level models that predict signal fidelity, crosstalk, timing, noise, attenuation, and bandwidth limitations across the quantum control and readout stack. Drive architecture trade studies and design decisions through simulation-based analysis, helping teams identify risks and optimize performance before hardware implementation. Establish simulation methodologies, modeling standards, and validation practices using electromagnetic, circuit, behavioral, and system-level simulation tools. Partner closely with Cryo-CMOS, packaging, readout, and qubit design teams to define interfaces and performance requirements for future quantum platforms. Document designs, results, and methodologies to enable reproducibility, knowledge sharing, and downstream integration OtherEmbody our Culture and Values QualificationsRequired/minimum qualifications Doctorate in Electrical Engineering, Physics, or related field AND 3+ years technical engineering experience. OR Master's Degree in Electrical Engineering, Physics, or related field AND 6+ years technical engineering experience OR Bachelor's Degree in Electrical Engineering, Physics, or related field AND 8+ years technical engineering experience OR equivalent experience.    Other Requirements:  Ability to meet Microsoft, customer and/or government security screening requirements are required for this role. These requirements include, but are not limited to the following specialized security screenings: Microsoft Cloud Background Check: This position will be required to pass the Microsoft Cloud Background Check upon hire/transfer and every two years thereafter.  Citizenship & Citizenship Verification: This role will require access to information that is controlled for...
