We are seeking a Senior Signal and Power Integrity Engineer to work in dynamic cross-functional role to optimize ASIC, package, PCB for mixed signal circuits. The candidate will have SI and PI ownership throughout the entire life-cycle of hardware that sits at the intersection of electrical, mechanical, thermal analysis, and RF engineering.  Working within the cryogenic complementary metal‑oxide semiconductor (cryo‑CMOS) team, you will have the opportunity to make a significant impact on a revolutionary technology. We are looking for an SI engineer responsible for signal integrity and power integrity designs for ICs and packages (substrates, interposers, redistribution layers, etc.). The work will include everything from IP evaluation in the silicon architecture stage, package performance evaluation, interconnect layer stackup selection and characterization, channel and PDN architecture, and PCB layout oversight.

Key Responsibilities

Responsibilities 

• Responsible for signal and power integrity portion of cryogenic ASICs, package, PCB, connector and cables.
• Model and simulate end-to-end high-speed channels including transceivers, IC package, PCB and cross-boards connectors/cables
• Utilize industry-standard tools and methodologies to perform a variety of time/frequency domain signal integrity analysis (SPICE, full-wave EM analysis, etc)
• Identify the link quality such as loss, reflection and crosstalk, and resolve the issues across transition structures for the entire channel i.e. die bump, package BGA, PCB, connector and cables.
• Interpret the simulation results to provide the design guidelines on board materials, stack-up, transmission line routings, component placement and layout optimization
• Define best practices, simulation workflows, test methodologies, signoff criteria, and lab equipment needs for all SI/PI requirements

• Collaborate closely with multidisciplinary partners—including ASIC designers, electrical engineers, and qubit measurement engineers—to inform and optimize system design. 
• Embody our Culture and Values
