Principal IEEE 802.11ah PHY IC Design Engineer


Are you an experienced Wi-Fi chip designer with a deep understanding of the IEEE 802.11 PHY? Do you want to play a key role in building next generation Wi-Fi chips that will truly enable the Internet of Things (IoT)? Keen to make a real difference in a VC-backed high-growth company while working in a dynamic & fun environment? Then join Morse Micro, Australia’s largest fabless semiconductor company! We opened our Cambridge office in January 2022 and are looking for the brightest of the brightest to join us in the The Bradfield Centre in the Cambridge Science Park.

You will be responsible for the design, verification and bring-up of an IEEE 802.11ah PHY to be used in Morse Micro’s family of Wi-Fi chips. You’ll work with the digital, systems and firmware teams to help architect and verify the PHY and ensure functional and performance goals are achieved.

Applicants will need to be experienced with digital PHY architecture and DSP design suitable for 802.11 protocols on advanced low-power process nodes. Your day-to-day will involve RTL design and simulation using contemporary languages and tools. You’ll work closely with the team to address and improve digital and system aspects of the design. You’ll also help with bringup of the PHY on silicon, evaluate performance of pre-production silicon and take your design to high-volume mass production.

Your responsibilities would include:

  • 802.11ah PHY development in Scala, SystemVeriliog and C 
  • Implementation of custom instructions in RISC-V architectures
  • Functional verification of 802.11ah PHY in RTL simulators, SDF-annotated gate level simulators and AMS simulators using SystemVerilog, Verilog-A, Matlab, C and Python
  • Work closely with the Systems team to achieve the best performance
  • Work closely with the Analog & RF to define and improve radio interface 
  • Work closely with the Firmware team to develop embedded PHY firmware
  • Assist with bring-up of silicon in the lab & debug PHY performance
  • Provide overall technical expertise and brilliance

To be successful in this role, the ideal candidate would have the following skills and experience:

Essential skills (you must have):

  • MSc in Electrical / Electronics / Communication Engineering or Computer Science
  • 8+ years experience as a PHY IC Design Engineer
  • Proven experience developing multiple blocks of 802.11 PHYs in complex SoCs
  • A deep understanding of the IEEE 802.11 PHY layer and familiarity with 802.11ah
  • A deep understanding of digital design fundamentals including low power and multi-clock-domain design
  • Hands-on experience with the Cadence or Synopsys simulation suite
  • Hands-on experience with Linux development environment staples such as make, shell scripts and Python
  • Excellent verbal and written communication skills
  • Proven to work constructively within your team and among other groups
  • Strong analytical and problem-solving skills
  • A determination to deliver even when subject to time pressures
  • A hands-on, practical attitude

Bonus skills (these will make you stand out in your application):

  • Proven experience performing phy bringup, debug and performance measurement on silicon in the lab
  • A good understanding of embedded processors, familiarity with RISC-V is a plus
  • A solid understanding of mixed signal ASIC design and simulation
  • Experience using the git revision control tool
  • Experience with development and debugging of digital designs from RTL design through to SDF-annotated gatesims

What we offer:

  • Competitive salary + excellent stock option package
  • Healthy work environment with sit/stand desks and large screens
  • Office perks such as stocked drinks fridge, snack bar and barista coffee
  • Newly fitted-out offices, with a relaxed, friendly work environment

Who we are:

Morse Micro is a fabless semiconductor company building Wi-Fi HaLow (802.11ah) chips for the Internet of Things (IoT). We are a team of wireless experts that love to innovate and invent. Together, we are building the world’s lowest power Wi-Fi technology that will enable billions of IoT devices to connect securely to the internet. We are a global team with offices in Sydney & Picton (Australia), Irvine & Boston (USA), Bangalore (India), Cambridge (UK) and Hangzhou (China).
