Job Title: Sr. Principal RFIC Design Engineer (grow into Head of Product)

Time Frame: ASAP start date sometime between Q3 and Q4 of 2024

Location: Berkeley, CA, hybrid work (MWF in the office, M-F when testing)

Role Type: Full-time hire

Company Description: We are an early-stage fabless semiconductor company designing cutting-edge wireless microchips for phased arrays. Founded by UC Berkeley PhDs, our unique technology promises significant reductions in power consumption (2-4x) across multiple markets from 5G to satellite communication (SATCOM) to radar (e.g. automotive radar / ADAS). We have raised seed funding to make our first prototype and are excited to change the world with your help. You will be joining a three person team so you will be integral to every decision we make and will have the opportunity to grow rapidly.

Job Description and Responsibilities: We are seeking a senior RFIC Design Engineer to be part of the core team. Their focus will be taking our first-of-its-kind mmWave front-end beamformer chips from initial concept to market-ready product. As a key RFIC Design Engineer, and a leader in the company, you will be responsible for:

Innovating on core technologies to make products that change the world
Designing, testing and architecting mmWave circuits for RF front-end blocks and products
Conducting system-level modeling of phased arrays, including custom chips and antennas
EM simulation and modeling of circuits, chip packages, PCBs and antennas
Performing RF bench-top and over-the-air testing
Collaborating with the founder and leading a growing team of engineers and contractors as needed

Required Qualifications:

Experience in mmWave front-end circuit architecture and design, including key blocks like LNAs, PAs, VGAs, phase shifters, inductors, transformers, and transmission lines, and associated circuit theory
Proficiency in mmWave EDA tools and key design flows
Experience in mmWave/RF testing for receivers, transmitters, transceivers, and front end RF circuits using industry-standard equipment
Advanced degree or significant industry experience to demonstrate a track record of excellence

Preferred Qualifications:

Strong background in transmit circuit design, especially high-frequency PA circuit techniques
Strong theoretical expertise in spatially selective multi-antenna wireless systems
Modeling of multi antenna signal chains (e.g. matlab, python, systemVue) to determine impact of non-idealities on system level metrics (e.g. EVM, SNR, BW)
Familiarity with relevant RF technology nodes (e.g. RF CMOS, SOI, SiGe)
Past experience with tapeouts, especially with DFM, reliability, and costing considerations.
Excellent communication skills, both written and oral, to present their work, decision-making process, and document their work
Strong interpersonal skills, with the ability to navigate complex engineering conversations to achieve the best result in a collaborative environment.
Ability to understand complex customer needs and translate them into clear engineering specifications
A track record of innovation and commitment to excellence along with a desire to change the world and have an impact with their work
