ElectronicsManufacturingSemiconductor
Responsibilities
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
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
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
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
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
Qualification
Required
10–15+ years in high-speed analog/mixed-signal IC design
Strong background designing laser drivers & TIAs for 50–200 Gbps+ optical links
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)
Bachelor's degree in Electrical Engineering or related field
Preferred
VCSEL driver/TIA experience strongly preferred, but experience with other laser types is welcome
Skills in firmware, embedded, and scripting is a plus
