Job Description

We are seeking a Senior Packaging Integration Lead to serve as the single-threaded packaging owner for one or more of Astera Labs’ advanced connectivity products. This role owns the end-to-end packaging solution from customer requirements and package architecture definition through development, qualification, and production ramp & represents packaging across the customer, internal cross-functional teams, business units, and the OSAT, foundry, and substrate supply base.

This is a senior individual-contributor technical leadership role who can set packaging technical direction, make architecture and technology-selection decisions, and drive alignment across stakeholders without direct authority. You will partner with packaging leadership on strategy while owning the technical direction for your products — defining package architecture and test vehicles to de-risk technology, and guiding execution engineers and external partners to deliver robust, manufacturable packages on schedule.

Key Responsibilities

Own the packaging solution end-to-end for assigned products — serve as the single point of accountability from a packaging standpoint across definition, development, qualification, and production ramp

Act as the primary packaging interface to the customer: capture and translate customer packaging, mechanical, thermal, SIPI, and reliability requirements into package architecture, specifications, and a clear execution roadmap

Define package architecture, structure and technology selection (e.g., 2.5D/3D integration, chiplet/interposer, CoWoS-class, organic substrate) with feasibility, cost, performance, and manufacturability trade-off analysis

Define and drive test vehicle (TV) strategy and requirements to de-risk new package technology, characterize interconnect/SIPI performance, and validate assembly and reliability ahead of product builds

Represent packaging across internal cross-functional teams — silicon design, package design, SIPI, thermal, product engineering, test engineering, validation, quality, and operations — and align packaging requirements to product and business-unit roadmaps

Partner with product planning, architecture, and program management on product roadmap, packaging feasibility, technology readiness, cost targets, and schedule commitments

Set technical direction with OSAT, foundry & substrate partners — driving technology selection, design-rule alignment, and development roadmaps across the supply base

Own package definition deliverables and sign-offs, including POR/TOR, design rules, stack-up, package BOM, DFM alignment, and pre-tape-out design-integration readiness

Drive risk identification, technology-gap closure, and mitigation across the product’s packaging roadmap; escalate and resolve critical cross-functional and supplier issues with urgency.

Communicate packaging status, risks, and key decisions to executive leadership, customers, and cross-functional stakeholders & external partners.

Basic Qualifications

B.S. or M.S. in Materials Science, Electrical Engineering, Mechanical Engineering, Chemical Engineering, or a related discipline; advanced degree preferred.

5-7+ yrs of experience in advanced packaging technologies such as 2.5D/3D integration, TSV, chiplets, and interposers. Optical / co-packaged optics experience is a plus.

Demonstrated end-to-end ownership of a product or platform packaging solution, from definition and architecture through qualification and production ramp

Experience defining package architecture and driving technology selection, including trade-off analysis across performance, cost, reliability, and manufacturability

Experience defining test vehicles and characterization/qualification strategies to de-risk new packaging technology.

Direct customer-facing experience translating product and system requirements into package specifications and commitments.

Strong architecture-level understanding of signal/power integrity (SIPI), thermal, and thermo-mechanical reliability considerations in advanced packages

Proven ability to lead and influence across internal cross-functional teams, business units, and external OSAT/foundry/substrate partners without direct authority.

Hands-on background working with foundries, OSATs, substrate suppliers, and material vendors.

Excellent communication, organizational, and executive-level presentation skills, with the ability to drive alignment across globally distributed teams.

Preferred Qualifications

Experience with UCIe / die-to-die interconnect and high-bandwidth chiplet integration

Experience with CoWoS-class, silicon-bridge, or advanced fan-out packaging platforms

Experience with co-packaged optics / optical packaging for scale-up connectivity

Track record engaging foundry and OSAT partners on advanced-packaging technology roadmaps

We know that creativity and innovation happen more often when teams include diverse ideas, backgrounds, and experiences, and we actively encourage everyone with relevant experience to apply, including people of color, LGBTQ+ and non-binary people, veterans, parents, and individuals with disabilities.
