Senior Principal RF Design Engineer
Finwave Semiconductor
Finwave Semiconductor is seeking a Senior Principal Design Engineer to spearhead
the development of next-generation RF Power Amplifiers (PAs) for the mobile handset
and SATCOM CPE markets. Leveraging our breakthrough 5V e-mode GaN-on-Si
technology, you will push the boundaries of energy efficiency and integration in RF
Front-End (RFFE) modules.
Role Overview
As a Senior Principal Design Engineer, you won't just be designing circuits; you will be the primary technical authority for our mobile handset and SATCOM roadmap.
Reporting directly to the Director of Engineering, you will lead the design and
prototyping of RF ICs and integrated modules that will power the next generation of
5G/6G smartphones and SATCOM Customer Premises Equipment (CPE).
Key Responsibilities
● IP Development: Identify and document novel circuit architectures and design
techniques to contribute to Finwave’s growing Intellectual Property (IP) portfolio.
● Technology Integration: Utilize Finwave’s E-Mode GaN-on-Si processes to
achieve breakthroughs in power density and energy efficiency for 5G/6G and
SATCOM CPE.
● Advanced PA Design: Execute high-performance MMIC/Hybrid PA designs for
mobile RF front ends, optimized for Envelope Tracking (ET) and Average Power
Tracking (APT) operation.
● End-to-End Development: Contribute to the full design lifecycle, including
architecture support, tape-out, prototype characterization, and debugging for high-
volume production
● Collaboration: Work cross-functionally to document designs and ensure thermal
management strategies are integrated into high-power density applications.
Qualifications & Skills
● Education: Master’s or PhD in Electrical Engineering, RF/Microwave Engineering,
or Physics.
● Experience: 20+ years of experience in RF semiconductor design, with a proven
track record of shipping high-volume PA products for the global smartphone market.
● Strong teamwork, communication, organization, and documentation skills.
● Industry Standards: In-depth understanding of RFFE requirements for Tier-1
smartphone OEMs and current 3GPP standards.
● Innovation Mindset: Proven ability to develop creative solutions for complex RF
challenges, supporting the generation of internal design specs and patents.
Technical Expertise
● Device Physics: Mastery of GaN (preferred), III/V (GaAs) or SOI. compound
semiconductor device physics and advanced modeling.
● Thermal Design: Deep understanding of thermal management strategies for high-
power density applications in a flip-chip configuration.
● EDA Tools: Expert proficiency in Keysight ADS and Ansys HFSS for MMIC and
laminate co-simulation.
● Linearity Management: Expertise in managing the trade-offs between Noise
Figure, Gain, and Input Third-Order Intercept Point (IIP3) for high-performance
mobile RFFEs.
● Hands-on experience with RF/microwave test equipment such as network
analyzer, probe station, source/load pull system, noise figure measurements, and/or
signal sources/analyzers that deal with modulated signals.
● Familiarity with Noise Theory is a plus: Design Low Noise Amplifier (LNA),
including impedance matching and impact of parasitic losses on the Noise Figure
(NF).
What We Offer
● Innovation: The opportunity to work with world-class innovators on revolutionary 5V
e-mode GaN technology.
● Impact: Shape the future of mobile and SATCOM communications by defining the
next generation of energy-efficient hardware.
● Compensation: Competitive base salary, 401(k) contribution, healthcare plan, and
stock options.
