Senior to Principal PLL Design Engineer roles

Locations: Irvine, CA or San Jose, CA

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. 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

Annual Base Salary Range: $150,000 - $250,000 (The final offer will be determined based on job-related skills, experience, qualifications, and location.)
