Key Responsibilities:
- Own the electrical and mechanical package design of advanced packages for high-speed optical interconnect and networking products, from concept and floorplanning through design release to manufacturing.
- Design advanced package architectures—including FCBGA/FCCSP, organic substrates, silicon interposers, and 2.5D/3D integration—supporting Co-Packaged Optics (CPO), Optical I/O, and pluggable optical modules.
- Develop high-density substrate routing and controlled-impedance interconnect for 112G, 224G, and 400G electrical interfaces, optimizing signal and power integrity across the package.
- Perform transmission line design, differential pair routing, via optimization, and return-current-path management to meet stringent high-speed performance targets.
- Define package stack-ups, design rules, and layout guidelines in partnership with signal integrity, power integrity, and thermal teams to meet electrical, thermal, and mechanical requirements.
- Address package reliability early in design, accounting for warpage, thermo-mechanical stress, underfill selection, and solder joint reliability through design and simulation trade-offs.
- Collaborate with silicon photonics, optical, and assembly teams on light coupling, fiber attach, and optical alignment considerations that impact package design.
- Drive design reviews, tolerance analyses, and design-for-manufacturability and design-for-assembly assessments with substrate vendors, OSATs, and internal manufacturing teams.
- Support package prototyping, bring-up, and qualification, resolving design issues and feeding lessons learned back into design rules and next-generation architectures.
Required Qualifications:
- MS or PhD in Electrical Engineering, Mechanical Engineering, Packaging Engineering, or related discipline (BS with extensive experience considered).
- 10+ years of experience in semiconductor package design.
- Proven experience designing advanced packages for high-speed networking, datacenter, or optical products.
- Strong knowledge of:
- FCBGA/FCCSP technologies
- Organic substrates
- Silicon interposers
- 2.5D/3D packaging
- Flip-chip assembly
- High-density substrate routing
- Experience designing packages supporting 112G, 224G, and preferably 400G electrical interfaces.
- Understanding of transmission line design, controlled impedance routing, differential pair design, via optimization, and return current paths.
- Familiarity with package reliability considerations including warpage, thermo-mechanical stress, underfill, and solder joint reliability.
- Experience working with substrate vendors and manufacturing teams.
- Strong communication and cross-functional leadership skills.
Preferred Qualifications
- Experience with silicon photonics packaging.
- Experience with Co-Packaged Optics (CPO), Optical I/O, or pluggable optical modules.
- Working knowledge of laser, photodiode, fiber attach, and optical alignment considerations.
- Familiarity with UCIe, PCIe, Ethernet, and CXL interfaces.
- Experience with AI accelerator or networking ASIC packaging.
- Knowledge of advanced cooling solutions for high-power packages.
