  • Evaluate and select materials including substrates, die attach, underfills, encapsulants, and thermal interface materials.

Collaboration & Execution

  • Partner with cross-functional teams to assess technical feasibility and identify suitable suppliers.

  • Work with contract manufacturers and internal teams to transition designs into production.

  • Prepare and maintain comprehensive design documentation.

Simulation & Reliability

  • Define and interpret multi-physics simulations (thermal, electrical, mechanical) to predict lifetime performance.

  • Ensure designs meet performance, reliability, and cost targets through rigorous evaluation.

Project Leadership

  • Provide regular updates on project status, milestones, and deliverables.

  • Support occasional travel to evaluate suppliers and assist with production ramp-up.

About You:

  • MS in Mechanical Engineering, Physics, or Materials Science (or BS with equivalent experience).

  • 10+ years of hands-on experience in semiconductor IC packaging, with a focus on SiP development.

  • Expertise in flip chip bonding, interposer design, and substrate layout.

  • Strong understanding of thermal management, signal integrity, and power integrity in package design.

  • Experience with high-voltage isolation techniques, reliability planning, and design for manufacturing.

  • Entrepreneurial mindset with a willingness to experiment, take initiative, and navigate ambiguity.
