Package Design Engineer

Key Responsibilities Execute package layout design and development for advanced packages, including 2.5D/3D IC, FCBGA, SiP, WLCSP, and multi-chip modules. Develop and maintain package CAD databases, ensuring strict accuracy and adherence to design guidelines, DFM (Design for Manufacturing), and DFA (Design for Assembly) to guarantee high manufacturability and high-yield reliability. Manage the complete design cycle: from schematic creation, netlist import, and footprint assignment to generating manufacturing outputs (Gerbers, drill data, and fabrication/assembly drawings). Create and modify substrate/RDL layouts, bump maps, escape routing, and power/ground structures. Collaborate closely with SI/PI, thermal, reliability, and DFT teams to support co-optimization and participate in critical design reviews. Ensure all designs strictly comply with foundry, OSAT, and manufacturing design rules (DRC, LVS). Support Engineering Change Orders (ECO) cycles, design updates, and version control throughout the project lifecycle. Qualifications 4+ years of hands‑on experience in Package CAD layout and development. Strong background in 2.5D/3D IC packaging, FCBGA, advanced substrate‑based packages, and multi‑die/chiplet‑based designs. High proficiency in industry‑standard tools such as Cadence Allegro Package Designer (APD/SiP), Siemens Xpedition/Substrate Integrator, or equivalent. Proven experience working with advanced manufacturing design rules and interfacing directly with Tier‑1 OSATs and foundries. Solid basic understanding of Signal Integrity (SI) and Power Integrity (PI) fundamentals, high‑speed routing, impedance control, and crosstalk mitigation. Strong communication, presentation, and documentation skills with a proven track record of working effectively in global, cross‑functional team environments. Education Bachelor’s or Master’s degree in Electrical Engineering, Microelectronics, Materials Science, or a related technical discipline.
