Role Overview

Astera Labs is seeking a Manager, Package Design Engineering to lead and scale our Package Design team in San Jose. In this high-impact role, you'll own the end-to-end delivery of advanced IC packaging solutions—from early architecture definition through production ramp—enabling the next generation of AI infrastructure and connectivity products.

As the semiconductor industry races toward chiplet-based architectures, 2.5D/3D integration, and ever-increasing bandwidth demands, packaging has become a critical differentiator. You'll build and mentor a high-performing team while driving cross-functional execution with silicon architecture, SIPI, PCB, validation, manufacturing, and external partners including substrate vendors and OSATs. Your work will directly impact Astera Labs' ability to deliver industry-leading PCIe, CXL, and Ethernet connectivity solutions to the world's most demanding hyperscale and AI customers.

This role offers the opportunity to shape design methodology, establish scalable standards, and enable chip-package-board co-design frameworks across multiple product lines in a fast-moving, innovation-driven environment.

Package Design Delivery

Own end-to-end package design execution including FCBGA/FCCSP, monolithic, multi-die, and chiplet-based designs from concept feasibility through tape-out and production

Define and review substrate stack-ups, pad stacks, routing strategies, and design constraints to meet electrical, thermal, mechanical, and manufacturability requirements

Drive technical tradeoffs across performance, cost, yield, and schedule, ensuring high-quality design closure and on-time delivery

Cross-Functional Collaboration

Partner with SIPI, silicon architecture, system/board design, and product teams to drive chip-package-board co-design and resolve system-level challenges

Collaborate with OSATs and substrate vendors to ensure design feasibility, manufacturability, and alignment with evolving design rules and technology roadmaps

Support adoption of advanced packaging technologies such as 2.5D, chiplet, CPO/CPC, and heterogeneous integration platforms

Methodology Automation

Develop and scale design methodologies and automation flows to improve efficiency, quality, and repeatability across the organization
