DFM R&D Engineer — Advanced Simulation & Materials

Job Title

DFM R&D Engineer — Advanced Simulation & Materials

Role Summary

The role combines finite element simulation and hands-on materials characterization to develop predictive models for semiconductor packaging, PCB systems, and SMT assemblies. The engineer will drive simulation-to-hardware correlation, influence design and reliability decisions, and partner with design, reliability, and manufacturing teams.

Experience Level

Senior — requires significant practical experience; posting specifies 7+ years of experience in finite element modeling.

Responsibilities

Deliver simulation-driven analysis and experimental correlation to reduce mechanical risk and inform product and manufacturing decisions.

• Develop and execute finite element models (implicit and explicit) for semiconductor packaging, PCB structures, and SMT assemblies.
• Analyze thermo-mechanical behavior including warpage, stress evolution, drop/shock, fatigue, and fracture.
• Lead or support material characterization (mechanical, physical, chemical) for microelectronics materials.
• Build, calibrate, and validate material models using experimental data.
• Design and execute DOE to correlate simulation with test results and support reliability projections.
• Drive early design optimization and support root-cause investigations of mechanical failures.
• Integrate module-level simulations into larger product assembly models and communicate results to cross-functional stakeholders.

Requirements

Required and preferred technical skills and domain experience.

• Must-have: 7+ years of finite element modeling experience; strong foundation in solid mechanics and thermomechanics.
• Must-have: Experience with CAE tools such as Ansys, Abaqus, or equivalent.
• Must-have: Experience working with materials used in microelectronics applications; hands-on materials characterization and model calibration.
• Nice-to-have: Experience in warpage, fracture mechanics, fatigue, or drop/impact modeling.
• Nice-to-have: Familiarity with semiconductor packaging and SMT processes and experience correlating simulation with physical testing.
• Nice-to-have: Understanding of DOE methodology and reliability physics; strong written and verbal communication skills.

Education Requirements

MS or PhD in Mechanical Engineering, Materials Science, Applied Mechanics, Chemical Engineering, or a related field (as stated in the posting).
