Job description

Meta is looking for an experienced ASIC Package Engineer to join its ASIC Packaging team. This role owns the technology development and qualification readiness of the package-to-board attach process for Meta's custom AI/ML and networking silicon — the critical interface where a larger than reticle sized, large-body advanced package meets the motherboard Meta designs. The engineer will lead the development and optimization of package interaction with board attach processes. The Meta Infrastructure team designs, builds, brings up, tests, and integrates custom and general-purpose silicon-based hardware systems that power Meta's platforms, deployed in data centers worldwide. Designs are published through the Open Compute Project Foundation. We are building a deep competency in packaging technology to support the rapid development of custom silicon and to develop scalable packaging solutions that are optimal for our next-generation AI/ML products and system-level performance. As die sizes grow past 3.3x reticle and packages move to lidless/lidded and asymmetric stackups, board technology development for next gen ASIC is very important to achieve desired yield due to challenges with package warpage, thermo-mechanical stresses, and solder-joint reliability. The person in this role serves as the primary packaging expert for package to board technology development, working shoulder-to-shoulder with Product Quality Engineering (PQE), Supplier Quality Engineering (SQE), and module design teams to turn it into a fully qualified, statistically controlled, high-yield manufacturing process. Own package-to-board interaction technology development for Meta's large-body advanced packages — how the package, substrate, and PCB behave together through assembly and in the field Characterize and mitigate package warpage and coplanarity across the reflow window for large-body and lidless packages Drive board-level reliability (BLR) strategy for ASIC packages in partnership with quality teams — thermal cycling, drop/shock, bend, and vibration Define and execute mechanical and electrical test vehicle (MTV/ETV) strategies to de-risk package-board interaction ahead of A0 silicon availability, including solder-joint evaluation by X-ray, cross-section, and dye-and-pry at the ODM Represent package-board interaction and board-assembly constraints in silicon/package/PCB/system co-design and product design reviews Collaborate with package design and module design teams to ensure design for manufacturability (DFM) considerations are incorporated into package and board development Develop and implement package-board interaction process specifications, design rules, and manufacturing guidelines for new package technologies Evaluate and qualify new package-board interaction equipment, materials, and processes to support technology roadmap requirements Partner with PQE, SQE, and ARD teams to establish quality standards, qualification criteria, and reliability requirements for package-board interaction processes Establish statistical process control (SPC) methodologies and yield improvement initiatives for package-board interaction assembly operations Own package-board interaction content in FMEAs, control plans, and key-characteristic definitions; support ODM line qualification and control-run gates with PQE Create, conduct, and analyze Designs of Experiments (DOE) for package-board interaction development and sustaining activities Drive supplier engagement and qualification for package-board interaction-related materials and equipment Bachelor's degree in Computer Science, Computer Engineering, relevant technical field, or equivalent practical experience Master's degree in Materials Science, Mechanical Engineering, Electrical Engineering, or a related field, or equivalent practical experience 8+ years of experience in semiconductor packaging with direct ownership of package-to-board assembly and reliability; package-board interaction process engineering or electronics manufacturing background Experience with package board technology processes including solder paste printing, pick-and-place, reflow soldering, and inspection methods Experience working with package assembly and ODM suppliers and driving process qualification and yield improvement programs Experience with failure analysis techniques for solder joint reliability and package-board interaction-related defects Experience collaborating with quality engineering teams (PQE/SQE) to establish process controls and qualification requirements Experience with statistical process control, process capability analysis, and Design of Experiments Willingness to travel internationally, typically once per quarter Experience with reflow temperature profiling, solder alloy and paste material selection, and low-temperature solder processes Experience with AI/HPC or networking hardware at data-center scale Experience with high-temperature warpage characterization and thermo-mechanical or finite element modeling (FEM) of packages and solder joints Hands-on experience with SPI, AOI, and X-ray inspection systems and associated data analysis Experience with large-body FCBGA, flip-chip, and 2.5D/3D advanced packages and their interaction with board-assembly constraints Master's degree or PhD in Materials Science, Mechanical Engineering, or a related discipline Knowledge of packaging and assembly industry standards Experience with ODM, CM/EMS, OSAT, and substrate supplier engagement and audit
