Qualifications

• Master’s or PhD in Electrical Engineering, Materials Science, Physics, Microelectronics, or related field.
• 7+ years’ experience in 3D integration and advanced packaging including TSVs, fine-pitch micro-bumps, and flip-chip bonding.
• Experience with 3D-IC layout, planning, and simulation platforms for multi-die co-design, TSV floorplanning, and vertical interconnect planning.
• Experience with multi-physics analysis tools such as Ansys HFSS/Q3D or equivalent for signal/power integrity, RF analysis, and cryogenic structural/thermal stress.
• Experience managing technical transfers and working closely with external semiconductor advanced packaging facilities, OSATs, or research partners.
• Proven ability to guide technical strategy and work effectively across multidisciplinary engineering teams.

Responsibilities

• Drive the high-level strategy and architectural design of 3D integrated circuits and multi-chip quantum modules.
• Develop advanced packaging solutions using TSVs, fine-pitch micro-bumps, and flip-chip bonding.
• Ensure packaging architectures and interconnects can withstand thermal cycling down to the millikelvin regime without delamination or loss of reliability.
• Contribute to early-stage architecture and co-design activities, ensuring the advanced packaging subsystem scales with the requirements of the overall quantum system.
• Develop simulation approaches to evaluate packaging and process options at DC and RF frequencies, including signal integrity, power integrity, thermal performance, and mechanical stress.
• Balance R&D execution with a strong focus on yield improvement, failure analysis, manufacturability, and long-term hardware reliability.
• Own relevant technical activities with external suppliers, OSATs, and research partners.
• Support the transfer of novel packaging designs into external manufacturing and advanced packaging lines.
