Principal Analog IC Design Engineers

Kforce's client, a rapidly growing and well-established semiconductor company is seeking a couple of Principal Analog IC Design Engineer to join their team. We are working directly with the hiring manager on this exclusive search. The company offers a highly competitive compensation package, including base salary, annual bonus, and equity. This position is 100% onsite. Overview: Join our team to lead the design of next-generation transimpedance amplifiers (TIAs) operating at multi-tens of GHz. These optical interface chips, integrated with our high-performance equalizers, set the industry standard for coherent long-haul, metro systems, and PAM4 data center applications. Key Responsibilities:

• Drive active circuit design and provide technical leadership across projects
• Design advanced TIAs using SiGe BiCMOS and FinFET CMOS technologies, achieving performance beyond industry benchmarks
• Develop millimeter-wave transmission line structures for superior signal integrity
• Create high-performance broadband analog circuits for optical front-end receivers
• Design supporting analog blocks such as linear regulators, AGC loops, sensors, and bandgap references
• Define microarchitecture for major circuit blocks and guide implementation by the design team
• Collaborate cross-functionally on post-silicon validation, qualification, mass production, and customer engagement
• Bachelor's degree in Electrical Engineering with 8-12+ years of relevant experience, or Master's/PhD with 5-8+ years in high-performance RF/Analog Receiver, TIA, Driver, or RFIC design
• Proven track record in chip tape-out and lab evaluation of high-performance receivers
• Proficiency with EDA CAD tools and hands-on IC performance measurement/debugging
• Strong foundation in transistor-level design, device physics, and control/feedback loop stability analysis

• Expertise in multiple technologies, especially SiGe BiCMOS and FinFET CMOS
• Experience designing physical layer ICs for high-speed optical fiber data communication
• Leadership experience mentoring junior designers and serving as chip lead
• Successful history of taking chips to mass production
• Ability to translate chip-level specifications into architectural designs
• Analog custom layout experience

• AGC loop design
• High-precision analog circuits (linear regulators, current sensors, bandgaps, drivers, DAC/ADC)
• Continuous-time linear equalizers
