We are seeking a Principal IC Design Engineer responsible for developing RF power amplifiers for wireless front-end module products. This role involves working with GaAs or SiGe HBT technologies and co-packaging with other ICs. Responsibilities include interfacing with project engineers, conducting linear and nonlinear simulations, supervising IC layouts, and validating designs through lab evaluation and prototype tuning. The ideal candidate should have a general understanding of high-volume semiconductor product development and a keen eye for detail, with an emphasis on time-to-market.

Qualifications

• BS with 9 years of experience, MSEE/Ph.D. with 7 years, or Ph.D. with 5 years
• Familiarity with amplifier modes (Class A, AB, B, C, F, F-1)
• In-depth knowledge of PA bias circuit designs
• RFIC/PA design experience using GaAs HBT, SiGe BiCMOS, GaN, or CMOS
• Experience with IC layout tools and layout planning
• In-depth knowledge of on-chip ESD protection strategies
• Expertise in Keysight ADS, Cadence, and associated simulation engines
• Familiar with 2.5D (EMX, Momentum, Sonnet) and 3-D (HFSS, FEM) EM design simulation tools
• Knowledge and understanding of laminate, wire bonding, WLCSP techniques, SMT components and multi-die FEM considerations.
• Experiences with thermal design consideration for RF front-end modules
• Strong lab skills for characterization, optimization, and debugging.
• Ability to execute project tasks with minimal supervision
• Solid Oral and written communication skills.

Responsibilities:

• Lead PA IC development, understanding system requirements for performance trade-offs
• Work with cross-functional teams for product development
• Perform feasibility analysis/simulation for new product development.
• Lead and collaborate die-level floor planning.
• Design/simulate fully integrated power amplifier ICs, considering package effects.
• Lead and collaborate with other team members to characterize, optimize, debug, and backfit the designs.
• Manage design trade-offs on performance, risk, yield, testability, and cost.
• Support hardware validations and analyze measurement data for performance enhancements.
• Develop and present design review and technical presentations to the technical community and product development teams.
