About the Team:

OpenAIs Hardware organization develops silicon and system-level solutions designed for the unique demands of advanced AI workloads. The team is responsible for building the next generation of AI-native silicon while working closely with software and research partners to co-design hardware tightly integrated with AI addition to delivering production-grade silicon for OpenAIs supercomputing infrastructure the team also creates custom design tools and methodologies that accelerate innovation and enable hardware optimized specifically for AI.

Role Overview

We are seeking an experienced engineer to lead the development of advanced packaging technologies that enable next-generation high-performance compute systems. This role sits at the intersection of chip architecture package integration and manufacturing scale-up driving breakthroughs in performance power thermal and reliability. The ideal candidate brings deep expertise in 2.5D and 3.5D large-reticle integration and Co-Packaged Optics (CPO) packaging with a proven ability to translate advanced concepts into qualified high-volume production solutions.

In this role you will:

• Architect develop and prototype advanced packaging solutions (2.5D/3D integration large-format interposers/bridges high-density substrates advanced assembly flows) and drive end-to-end qualification for high-volume production.

• Develop packaging concepts and requirements to support CPO packaging including optical/electrical co-integration considerations thermal/mechanical constraints and high-volume manufacturability.

• Lead large-reticle and multi-die integration strategies including mechanical/thermal co-design warpage control and yield/reliability risk mitigation across package scale-up.

• Identify and solve fundamental technical challenges in package architecture integration and manufacturability for high-performance compute chips.

• Collaborate closely with cross-functional teams (silicon architecture SI/PI thermal mechanical system test and manufacturing) to align package development with product requirements and program milestones.

• Drive vendor engagement and technical alignment with external partners (foundry/OSAT/material/tool vendors) including technology selection DOE planning and qualification readiness.

You might thrive in this role if you have:

• Large-reticle / large-body-size integration including interposer/bridge-based architectures package-scale mechanical/thermal risk management and manufacturability at scale.

• Hands-on experience with CPO packaging including package-level optical integration constraints and cross-domain trade-offs (electrical/optical/thermal/mechanical).

• Proven track record developing and productizing large-format high-power high-speed advanced packaging technologies for high-performance compute products.

• In-depth expertise across advanced packaging techniques and platforms used in the semiconductor industry (2.5D 3D stacking interposers/bridges high-density substrates advanced materials and assembly).

• Strong understanding of chippackage co-design: how chip architecture I/O power delivery and floorplan decisions interact with packaging architecture and constraints.

Preferred Qualifications

• Solid understanding of thermal and mechanical interactions in large-format packages (warpage stress lid/heat-spreader/cold-plate interfaces material interactions).

• Working knowledge of reliability requirements and qualification methodologies for advanced packages (JEDEC/industry practices failure analysis DOE-driven learning cycles).

• Familiarity with system-level considerations and chip architecture fundamentals (I/O topology HBM/advanced memory integration SI/PI constraints module-to-system integration).

To comply with U.S. export control laws and regulations candidates for this role may need to meet certain legal status requirements as provided in those laws and regulations.
