ASIC Package Engineer

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.

Responsibilities

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
