Stealth Company

Other Engineering · Full-time
Posted on Tuesday, April 11, 2023

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 funding to make our first prototype and are excited to change the world with your help. You will be joining a two person team so you will be integral to every decision we make and will have the opportunity to grow rapidly.


We are seeking a Senior Principal 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 Senior Principal RFIC Design Engineer, and a leader in the company, you will be responsible for:

  • 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
  • Managing engineering infrastructure including EDA tools and servers
  • Collaborating with the founders 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 core 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
  • No formal education requirements but advanced degrees can demonstrate a track record of excellence

Preferred Qualifications:

  • Strong theoretical expertise in spatially selective multi-antenna wireless systems
  • Proficiency in EDA tools for antenna design and simulation at mmWave frequencies
  • Familiarity with relevant RF technology nodes
  • Past experience with commercial (or large scale academic) 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.
  • Desire to change the world and have an impact with their work.
