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

**Job Title** Senior/Principal Analog Mixed-Signal Design Engineer, microLED Transmitter **Job Title** Senior/Principal Analog Mixed-Signal Design Engineer, microLED Transmitter **About the Role** 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. **Key Responsibilities** - 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. **At the principal level, you will also** - 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. **Qualifications** **Required** - 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 SerDes 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. **Preferred** - 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). **Key Competencies** - 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.
