About the Job
About the job: 
Are you a PLL Design Engineer, who is seeking an amazing opportunity delivering disruptive High Speed Interconnect Technology to power next generation AI? We are looking for a High-Speed CMOS PLL Analog Design Engineer –who is excited to join a fast-growing Start-Up Company with a key role for expert in clocking circuits for next generation optical transceivers, high-speed SerDes, and ADC/DAC systems 

Preferred Location: On-Site at one of our offices: San Jose, CA, or Irvine, CA HQ.

Alternate Locations: Vancouver, British Columbia; Ottawa, Ontario.

Candidate will have the opportunity to architect and design PLLs for next generation transceivers. 

What You Will Do: 
  • Understand trade-offs between different PLL topologies (e.g., integer-N, fractional-N, all-digital/ADPLL) to meet specifications for power, area, jitter, and frequency range. 
  • Architect, design and simulate analog/mixed-signal PLL building blocks (VCOs, charge pumps, dividers, PFDs, Loop Filters) at transistor level using tools like Cadence Virtuoso and Spectre. 
  • Address challenges in advanced node technologies, such as self-heating, electromigration, voltage-controlled oscillator (VCO) linearization and device-level noise optimization. 
  • Supervise and verify layouts produced by layout engineers to ensure floorplanning, matching, and parasitic minimization using advanced node technologies. 
  • Be responsible for PLL bring up in the lab, conducting performance characterization using state-of-the-art lab equipment. 
  • Conduct comprehensive system-level simulations and validation for PLL integration into advanced transceiver technologies. 
     
What You Will Bring: 
  • Master’s degree and/or PhD in Electrical Engineering or related fields with 5+ years of relevant experience in PLL design, and production level tape-out experience. 
  • Must have extensive experience with advanced node technologies (16nm/12nm, 7nm, 5nm, 3nm, 2nm processes). 
  • Deep understanding of phase noise analysis, VCO design, LDOs and supporting circuitry associated with PLLs. 
  • Proficient in cadence virtuoso, electromagnetic simulator (e.g., EMX/HFSS), and MATLAB for system-level modelling. 
  • Strong communication and documentation skills.
