Senior/Principal Analog Mixed-Signal Design Engineer, microLED Transmitter

Avicena is developing high-speed parallel optical links built from arrays of microLED transmitters and photodetector receivers. We are looking for an analog mixed-signal engineer to design the high-speed drivers that modulate our microLED arrays. You will own driver circuits from specification through post-layout signoff and silicon correlation, working with the TX lead, the optical device team and layout. We are hiring at senior through principal level;

title and scope will match experience.

• Design and simulate high-speed microLED driver circuits: output drivers, pre-emphasis and equalization, DACs for drive-level and trim control, bias generation and pulse shaping.
• Optimize dense driver arrays for matching, supply noise sensitivity and power per lane.
• Design calibration and trim circuits with the digital team.
• Work with the optical device team on LED electrical models and drive requirements.
• Verify designs across PVT and Monte Carlo, and take them through post-layout extraction and signoff with layout.
• Deliver behavioral models and correlate them with transistor-level results.
• Support silicon bring-up and correlate measurements with simulation.

• Set the technical direction for transmitter circuits and drive architecture trade-offs with the TX lead and system architect.
• Lead design reviews and define verification and signoff criteria for TX blocks.
• Mentor engineers and review their designs.

• MS in Electrical Engineering (or BS with equivalent experience) and 5+ years of analog/mixed-signal design.
• Taped-out high-speed transmitter or driver circuits, such as laser, VCSEL or LED drivers, or Ser Des transmitters.
• High-speed driver and DAC design experience.
• Design experience in FinFET or other advanced CMOS processes.
• Proficiency with Cadence Virtuoso and Spectre, and with post-layout verification.

• Optical transmitter design for laser, VCSEL or LED-based links.
• Supply integrity and power delivery awareness for large driver arrays.
• Behavioral modeling in Verilog-A.
• Hands-on lab characterization.
• 10+ years with technical leadership of transmitter designs through production (principal level).

• Analytical: reasons clearly about speed, power and matching.
• Ownership: carries a block from specification to silicon.
• Collaboration:
  
  works across device, layout and digital teams.
• Clear communicator: documents designs and trade-offs concisely.
