• Enable smooth movement of prototypes and development lots across fab and assembly workflows.
• Develop deep understanding of temperature-dependent material properties including:

• Superconducting transitions
• Electrical resistivity and RF loss
• Thermal transport behavior
• Mechanical stress/CTE mismatch

• Define and utilize characterization methods (electrical, thermal, structural) to evaluate materials performance.
• Correlate material behavior with device- and system-level performance impacts.
• Identify and analyze failure mechanisms, including:

• Delamination and interface failure
• Diffusion / intermetallic formation
• Stress-induced cracking during thermal cycling

• Develop material solutions and process mitigations to enhance reliability.
• Drive long-term reliability strategies for cryogenic operation.
• Develop materials solutions that:

• Improve yield and process robustness
• Reduce cycle time and cost

• Partner with integration teams to ensure scalable and manufacturable material choices.
• Work directly with material suppliers and equipment vendors to:

• Evaluate new materials (e.g., superconducting films, hybrid materials)
• Define material specifications and qualifications

• Collaborate with OSATs and partners to enable wafer-level and die-level integration flows.
• Interface across:

• Interconnect / bump / TSV / assembly integration teams
• Device / qubit / system engineering teams

• Enable co-optimization of materials + process + system architecture.
• Drive development of next-generation materials for scalable quantum systems, including:

• Superconducting interconnect stacks
• Cryogenic-compatible dielectrics and bonding materials

• Contribute to APPC quantum packaging roadmap and capability build-out.
• Track and evaluate emerging materials and integration schemes.
• Generate:

• Material specifications and process guidelines
• Integration documentation and characterization reports

• Communicate results to internal and external stakeholders.
• Support IP generation, publications, and conference outputs.
• Define materials strategy across multiple quantum platforms and customers.
• Lead external technical engagements (e.g., R&D consortia, suppliers, quantum customers).
• Mentor engineers and establish materials selection frameworks and best practices.

Other Responsibilities:

• 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 in Singapore.
