Delos Data

Engineer

• Architect and deliver advanced multi-die IC packages for high-performance AI accelerators
• Select and design optimal multi-die package types, balancing electrical performance, thermal behavior, cost, and manufacturability
• Define package specifications, bump map, ball map, interposer requirements, and mechanical constraints
• Define substrate stack-ups, bump pitch, ball pitch, routing, via structures, and material choices
• Perform high-speed signal escaping, routing, and power distribution network design
• Manage subcontractors and work directly with TSMC and/or OSAT on bumping, substrate options, and advanced packaging flows
• Partner with IC design, physical design, SI/PI, and board teams to meet system-level needs
• Evaluate emerging packaging technologies and drive adoption for next-generation products
• Support package-level bring-up, failure analysis, debug, and qualification

Principal Package Engineer

• Develop, implement, and maintain RTL verification environments using UVM or equivalent methodologies
• Create and execute coverage-driven verification plans aligned with design specifications
• Use EDA DFT tools such as TestMax and Tessent to create and run pre-silicon test cases for MBIST and scan fabric
• Develop directed test cases for non-vendor-supplied DFT logic
• Assist in verifying ATPG patterns, especially at SoC level, and manufacturing reset sequences
• Analyze simulation results, debug complex verification and design issues, and perform root-cause analysis with DFT design engineers
• Implement and track functional and code coverage, driving verification to closure
• Develop reusable verification components and write SystemVerilog Assertions
• Participate in design and verification reviews, contributing to testability, correctness, and optimization
• Automate regression testing and enhance verification infrastructure using Python and scripting
• Contribute to continuous improvement of verification processes, tools, and methodologies
• Support post-silicon test bring-up debug with DFT designers
