Meet the Team

Cisco Silicon One is a business organization with a long track record of building complex and high-performance Silicon ASICs. Our silicon devices drive the world’s most complex networks and carry over 90% of IP traffic. We are a highly specialized ASIC team with experts in all aspects of advanced IC package design and heterogeneous system integration. Our substrates use the latest 2.5D fanout technologies for large-scale integration, using the latest signaling and data transfer technologies. 

Your Impact

We are seeking a skilled and driven ASIC Mechanical Engineer to join the Cisco ASIC Group.  In this role, you will focus on mechanical and thermomechanical simulations of ASICs and complex silicon packages.  Your simulations will directly facilitate product design, ensure mechanical reliability, and accelerate time to market for high-performance Cisco Systems.

You will:

Collaborate with a globally distributed team across multiple time zones, contributing to innovative, simulation-driven design across packaging, reliability, thermal, and hardware engineering groupsPerform finite element analysis to evaluate thermal mechanical stress, warpage, solder joint reliability of ASIC package, substrates, and advanced packaging assemblies Simulate and analyze linear/nonlinear material behaviors, such as plasticity, creep, and viscoelasticity, relevant to solder joints, Copper, stiffener, and underfills Develop and automate simulation workflows using Python, Fortran or similar scripting tools to streamline analysis and reporting Provide clear simulation results to support mechanical design, root cause analysis, and risk mitigation Support design optimization at early phase of product development and failure investigations by correlating FEA predictions with test data and field returns Document and present analysis results, assumptions, and design recommendations in a clear, structured format

Minimum Qualifications 

Bachelors + 7 years of related experience, or Masters + 4 years of related experience, or PhD + 1 years of related experience At least 3 years of experience in mechanical design and thermomechanical simulation of semiconductor packages Hands-on experience with 3D modeling, finite element analysis using ABAQUS or ANSYS Flexibility to coordinate and communicate across different time zones, supporting global project teams in the US and Asia

 

Preferred Qualifications 

5+ years of experience in mechanical or thermomechanical simulation of semiconductors or electronics packaging systems Knowledge of GD&T, design-for-reliability (DfR) principles and industry standards (JEDEC, IPC, etc.) Experience in flip chips, 2.5D/3D advanced packaging, and/or heterogeneous integration technologies Familiarity with material mechanical behavior and material characterization and working knowledge of reliability qualification of semiconductor packages Proficiency in script-based automation for simulation to improve simulation efficiency and consistency
