Quantum Assembly Engineer

Global Foundries Fab9 is seeking a highly skilled and motivated R&D assembly engineer to become part of our Quantum Advanced Packaging team. This role will drive next‑generation assembly scaling development in our Advanced Packaging and Photonics Center (APPC) and with external partners, owning development and integration of cryogenic, superconducting assembly processes to enable scalable quantum hardware packaging.

Global Foundries is a leading full‑service semiconductor foundry providing a unique combination of design, development, and fabrication services to some of the world’s most inspired technology companies. With a global manufacturing footprint spanning three continents, we make possible the technologies and systems that transform industries and give customers the power to shape their markets.

• Lead development of cryogenic‑compatible assembly processes for 2D, 2.5D, and 3D quantum packaging platforms.
• Define assembly schemes for:
  • Flip‑chip / micro‑bump / superconducting bump attach
  • Die‑to‑wafer (D2W), wafer‑to‑wafer (W2W), and hybrid bonding
• Ensure processes are optimized for low‑loss, superconducting signal paths and mechanical integrity at cryogenic temperatures.
• Own assembly integration flows from incoming wafer/die through package build.
• Coordinate process interactions across:
  • Bump/interconnect teams
  • TSV/interposer integration
  • Substrate/package assembly
• Define and maintain process flow specifications, traveler flows, and assembly integration schemes.
• Enable prototype builds, ensuring smooth execution through internal and external assembly lines.
• Drive assembly readiness for new technologies, including tooling, materials, and process modules.
• Support hands‑on build/debug during early development phases.
• Develop and implement strategies to:
  • Improve assembly yield and throughput
  • Reduce defects (alignment, voiding, delamination, interconnect failures)
• Lead failure analysis and root‑cause investigations for assembly‑related issues.
• Work with test and systems teams to ensure assembled hardware meets:
  • Cryogenic reliability across thermal cycles
  • Electrical and RF/microwave integrity requirements
• Support hardware bring‑up, validation, and debug in cryogenic environments (e.g., dilution refrigerators).
• Evaluate and select assembly materials and interfaces (e.g., indium, superconducting metals, underfills, substrates) for cryogenic operation.
• Work with equipment teams to define requirements for:
  • High‑precision alignment / bonding tools
  • Cryogenic‑compatible materials handling
• Develop deep understanding of tool capability vs. quantum packaging requirements.
• Collaborate with:
  • Quantum device / qubit teams
  • Packaging & integration engineers
  • Cryogenic system and hardware teams
• Interface with OSATs, assembly partners, and suppliers to co‑develop and scale assembly processes.
• Drive development of next‑generation assembly architectures for scaling qubit systems:
  • High‑density interconnect co‑packaging
  • Interposer‑based and 3D stacked integration
• Contribute to APPC / Quantum packaging roadmap and capability build‑out.
• Generate and maintain:
  • Assembly process flows
  • Specifications and integration guidelines
• Provide clear technical updates, data analysis, and reports to stakeholders.
• Support IP generation, publications, and conference contributions.

• Perform all activities in a safe and responsible manner and support all Environmental, Health, Safety & Security requirements and programs.
• Take part in hiring of other Advanced Packaging team members.
• Mentor and guide new hires to assume their roles and responsibilities.
• Other duties as assigned by manager.

• Education – Master’s in Electrical Engineering, Mechanical Engineering, Chemical Engineering, Materials Science or related field from an accredited degree program.
• MS degree with at least 10 years of prior related work experience.
• In depth knowledge of BEOL processes and integration, bump/wafer finish integration, wafer test/probe, OSAT collaboration, and package development & assembly.
• Strong problem solving and technical trouble‑shooting skills including expertise in design of experiment.
• Must have at least an…
