Original job description

Overview

Rambus, a leading provider of semiconductor products and silicon IP that make data faster and safer, is seeking an exceptional Principal Package Development Engineer to join our Package Engineering team in San Jose, California. In this role, you will collaborate with accomplished engineers and cross-functional teams to develop high-performance semiconductor products for data-intensive applications.

This full-time position reports to the Director of Package Engineering. You will lead package development activities from early product definition and chip-package co-design through qualification and manufacturing ramp. Your work will focus on enabling reliable, high-yield, cost-effective, and low-defect production across multiple package technologies.

You will collaborate with internal engineering teams, outsourced semiconductor assembly and test providers, and material and component suppliers to ensure package performance, qualification, and manufacturing readiness across the Rambus product portfolio.

Rambus offers a flexible, hybrid work environment for most office-based roles. Employees are encouraged to work onsite an average of at least three days per week, with up to two days of remote work.

Responsibilities

Lead early chip-package co-design and package technology selection for new products.
Develop package solutions across technologies including FCCSP, FCBGA, FCQFN, WLCSP, QFN, and related package platforms.
Translate product, die, electrical, thermal, mechanical, reliability, manufacturing, and cost requirements into executable package designs.
Partner with Chip Design, SI/PI, Product Engineering, Test, Quality, Reliability, Marketing, Supply Chain, and other cross-functional teams throughout the product development lifecycle.
Evaluate package architecture and material options against performance, cost, manufacturability, yield, reliability, and schedule requirements.
Lead technical engagement with OSAT partners and substrate, leadframe, and material suppliers through design reviews, development builds, qualification, and production ramp.
Review package drawings, substrate and leadframe designs, material selections, design rules, and supplier manufacturing requirements.
Identify package-related technical risks and drive mitigation plans, root-cause investigations, and corrective actions.
Support thermo-mechanical modeling and simulation activities, including model development, boundary-condition definition, correlation, and interpretation of results.
Drive package qualification planning and execution in collaboration with Quality and Reliability Engineering.
Support successful transfer of new package technologies and products into high-volume manufacturing.
Improve package-development workflows, design methodologies, supplier engagement models, and technology roadmaps.
Document technical decisions, design requirements, development results, risks, and lessons learned.

Qualifications

Bachelor’s degree in Materials Science, Mechanical Engineering, Electrical Engineering, Chemical Engineering, or a related technical discipline.
At least seven years of semiconductor package development experience, including direct involvement in new product introduction and manufacturing ramp.
Demonstrated experience developing multiple semiconductor package types and successfully transitioning products into volume production.
Working knowledge of flip-chip, wire-bond, wafer-level, leadframe-based, and organic laminate package technologies.
Experience with high-speed or high-pin-count semiconductor devices.
Understanding of signal integrity, power integrity, thermal, mechanical, and reliability considerations in package development.
Strong knowledge of organic substrate and leadframe design, materials, fabrication processes, and manufacturing capabilities.
Experience working directly with OSAT partners and package-component or material suppliers.
Understanding of package-material properties and their impact on manufacturing and reliability.
Experience with relevant package qualification and reliability methods, including temperature cycling, HAST, mechanical shock, vibration, thermal characterization, and outgassing assessment.
Working knowledge of applicable JEDEC standards and package-design specifications.
Strong analytical, problem-solving, project-management, and technical communication skills.
Demonstrated ability to lead technical activities across cross-functional and globally distributed teams.

Preferred Qualifications

Master’s degree or Ph.D. in Materials Science, Mechanical Engineering, Electrical Engineering, Chemical Engineering, or a related discipline.
Experience with advanced silicon nodes and complex, high-performance package architectures.
Experience using Cadence Allegro Package Designer and AutoCAD.
Experience with thermal or thermo-mechanical simulation tools and model correlation.
Familiarity with package warpage, interconnect fatigue, delamination, moisture sensitivity, material adhesion, and other package-level reliability mechanisms.
Experience developing or qualifying package materials, including substrates, leadframes, mold compounds, underfills, die-attach materials, and solder interconnects.
Experience establishing package technology roadmaps, supplier design rules, or standardized package-development processes.
