Analog - Sr/Principal High-Speed Analog Circuit Design Engineer (Optical I/O – Laser Drivers & TIAs)

Key Responsibilities:

• High-Speed Analog Design
Design and implement laser drivers, TIAs, limiting amps, EQ blocks, biasing circuits, and other analog front-end components for 50G
• 200G data rates.
• Build circuits that hit ambitious bandwidth, noise, jitter, and power targets under real system constraints.
• Advanced Silicon Development
• Execute transistor-level design in 12nm-and-below CMOS/FinFET technologies.
• Run comprehensive simulation flows: transient, AC, noise, corner/PVT, BER, and post-layout verification.
• Collaborate closely with layout to optimize parasitics, floorplan efficiently, and maintain signal integrity.
• Optical/Electrical Co-Design
• Work with internal teams and laser/PD vendors to align on electro-optical requirements.
• Understand laser dynamics (preferably VCSEL behavior), modulation characteristics, thermal effects, parasitics, and reliability constraints.
• Shape electrical–optical tradeoffs to achieve robust high-speed performance in real environments.
• Silicon Bring-Up & Validation
• Lead lab characterization, debug, and performance verification for high-speed optical paths.
• Analyze data from scopes, BERTs, and optical test setups to guide iteration and improve link behavior.
• Support product integration and help drive the design into production.
• Technical Leadership in a Startup Environment
• Mentor junior designers and raise the analog design bar across the team.
• Work cross-functionally with mixed-signal, digital, packaging, FW, and system teams.
• Influence product direction through data-driven insights and grounded technical judgment.

Qualifications:

• 10–15+ years in high-speed analog/mixed-signal IC design.
• Strong background designing laser drivers & TIAs for 50–200 Gbps+ optical links.
• VCSEL driver/TIA experience strongly preferred, but experience with other laser types is welcome.
• Deep understanding of broadband analog techniques, low-noise design, and high-speed signaling.
Proven silicon track record from concept tapeout bring-up
• production.
• Experience with optical link budgets, fibers, packaging effects, and thermal impacts.
• Ability to move fast, make clear decisions, and thrive in a high-growth startup environment.
• Knowledge of common interfaces: I2C, JTAG, USB, GPIO
• Experience with microcontroller and FPGA integration
• Proficiency with PCB design software (Allegro PCB or equivalent)
• Skills in firmware, embedded, and scripting is a plus
• Bachelor's degree in Electrical Engineering or related field
