This is a high-impact senior individual contributor role focused on aligning electrical, thermal, and mechanical design requirements across functions, enabling robust package implementation, and guiding package technology decisions for NPO and CPO products.

Responsibilities

• Define photonics package architecture, define electrical and optical interface specifications, and establish signal integrity and power integrity requirements.

• Establish and manage Thermal Design Power (TDP) budgets and thermal performance targets.

• Drive cross-functional alignment with EIC, PIC, and hardware teams on co-design constraints and drive system optical link budget .

• Partner with validation, test, and reliability teams to define DFT and DFR requirements and acceptance criteria.

• Finalize bump map and ball map, and manage ECOs and revision control of package design databases.

• Lead package-level design reviews and own the package design technical roadmap.

Basic Qualifications

• B.S., M.S., or Ph.D. in Electrical Engineering, Mechanical Engineering, Materials Science, Physics, or a related field.

• 10+ years of experience in semiconductor or photonics package development, package design, or package integration, with demonstrated technical leadership.

• Experience working across chip, board, and system-level design electrical and optical interfaces in complex product development environments.

• Experience with package EDA tools and electrical simulation tools, including Cadence APD+ and Ansys HFSS.

• Experience with advanced packaging design, including 2.5D and 3D package architectures.

• Familiarity with package design flows, design database management, and engineering change control practices.

• Ability to drive technical decisions, resolve cross-functional issues, and communicate architecture direction clearly to stakeholders.

• Strong foundation in design reviews, risk assessment, and design quality from concept through production release.

Preferred Qualifications

• Experience with industry-standard optical interfaces and interconnect technologies relevant to package design.

• Experience with advanced photonics packaging technologies for data center interconnects .

• Experience supporting package bring-up and correlating design assumptions with validation results.

• Experience supporting cross-functional design closure with silicon, photonics, board, validation, test, and reliability teams.

• Knowledge of package design for NPO or CPO products.
