Principal Analog​/Mixed-Signal IC Design Engineer

Acacia designs intelligent transceivers using advanced signal processing and photonic integration for the 100G, 400G and 1T bit speed fiber optic transmission market deployed in data center, metro, long-haul and ultra-long haul telecommunication networks.

You will provide technical leadership in definition and implementation of large-scale block on a complex chip.

You will mentor team members and track deliverables, participate in peer review of complex IC designs.

You will provide expert advice on design methodology from conception to production.

Actively contributes to Cisco research initiatives

You will work with cross-functional groups across Cisco to define future strategies, ensuring alignment and that we are building the accurate and optimized solutions for all teams.

You will work with other Acacia mixed-signal engineers to collaborate to provide an optimized design that will integrate into the ASIC. In addition, you will have the opportunity to interact with other Acacia groups including digital/DSP design, system design, package design, and module design.

You are enthusiastic about developing high-speed AMS circuits and outstanding products. You are detail-oriented, energetic, and driven to tackle difficult problems.

You can work independently but also thrive in a collaborative, team-oriented environment, learning from and teaching your colleagues.

Your communication skills enable flawless teamwork within and across teams, steering development positively.
