Principal RFIC Design Engineer – Sophia Antipolis (France) or Minneapolis, MN, USA


We are searching for a Principal-level radio frequency integrated circuit (RFIC) design engineer to join our RFIC designers to help lead Sequans in the development of RF transceivers to address the IoT and 5G market. Working within a dynamic design team you will participate in the development of next-generation RFIC products for IoT and 5G wireless communication networks.


  • Specify, design and verify key circuits and sub-systems of integrated RF transceivers
  • Work closely with other teams to facilitate the design and production process,e.g. Software, Signal Processing, Product Integration, Sales & Marketing
  • Provide broad technical expertise and mentor junior engineers within the team

Required Experience:

  • Engineering degree in a relevant discipline. BSc, MSc or equivalent
  • 7 to 15 years experience of relevant IC development
  • Recent successful RFIC project contributions on highly integrated RF transceivers,ideally related to broadband wireless communication systems, e.g. WiFi or LTE,on a nano-metre scale RF-CMOS technology
  • Understanding of Low power / low noise design techniques for Analogue and RF
  • Knowledge of Design for Manufacture considerations on cutting edge processes
  • Full appreciation of RF and baseband layout techniques

Required Detailed Knowledge at Circuit Level:

  • Multi-Band RF circuit design in the 700MHz to 7GHz range
  • Proficiency in Cadence and/or Mentor frontend and backend tools are absolutely required
  • Familiarity with RF lab equipment such as signal generators, spectrum analyzers, and vector signal analyzers is required

Additional Useful Experience May Include:

  • RFIC Sub-system and block level definition & specification
  • Integrated single chip RF + Digital baseband projects
  • Top level chip simulation and functional verification
  • Analogue behavioral language modeling (e.g. Verilog-AMS)
  • Mixed-mode simulation environments (e.g. mixed verilog and device level )
  • Direct conversion Rx and Tx architectures and associated considerations
  • DFT and BIST for Analogue and RF circuits
  • Silicon test and de-bugging


  • Highly motivated, pro-active self-starter
  • Strong sense of ownership and responsibility
  • Creative thinker with strong problem solving skills
  • Team oriented attitude
  • Ability to thrive in a multicultural environment
  • Ability to communicate well with cross-functional teams
