About Acacia
Acacia develops intelligent, high-speed transceivers using advanced signal processing and photonic integration for 100G, 400G, and 1Tbit fiber optic transmission, deployed in data center, metro, long-haul, and ultra-long-haul telecom networks.
Key Responsibilities
1. Develop, architect, design, layout, measure, and productize ultra-deep sub-micron CMOS mixed-signal ICs (>25Gb/s) for optical communications.
2. Lead major block design on complex chips, mentor team members and track deliverables.
3. Participate in peer reviews, drive solid design methodology, and ensure production-readiness.
4. Collaborate with packaging and hardware teams to meet signal and power integrity specs.
Collaboration
5. Work closely with mixed-signal, digital/DSP, system, package, and module design teams.
6. Participate in a supportive, collaborative engineering environment.
