What You’ll Be Doing

• Design the opto-mechanical elements of next-generation optical products for telecom, data centers, and AI/ML infrastructure, from concept to completion, in collaboration with cross-functional teams. Ensure designs meet opto-mechanical, thermal performance, reliability, time-to-market, and cost requirements
• Lead concept design evaluations and define the optimal design architecture in collaboration with simulation, optical, design authority, tooling, hardware/electrical, and process teams
• Conduct design reviews, focusing on design for manufacturability (DfM), engineering analysis to predict product performance and reliability, design optimization, material selection, dimensional stability of optics, and tolerance analysis
• Engage with suppliers to explore new technologies and materials for opto-mechanical packaging and advanced semiconductor packaging, including flip chips, 2.5D/3D advanced packaging, silicon photonics, adhesives/epoxies/underfills, ceramics, thermal interface materials, hermetic packaging technologies, and thermoelectric coolers
• Perform FEA to evaluate stress, warpage, solder joint reliability in advanced electronics packaging assemblies
• Simulate/quantify linear/nonlinear material behaviors of BGA solder joints, copper pillars, underfills in terms of plasticity/viscoelasticity, creep, etc.
• Drive design of experiments (DOEs) to guide design decisions and process improvements, covering chip warpage, stress-optics, dimensional stability of optics, shock and vibration, and thermal performance
• Document design files, best practices, and internal design guidelines to ensure knowledge retention and continuous improvement
