About The Position

Join the Cisco Acacia Communications team in developing 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. Acacia's silicon team provides a unique experience for ASIC engineers by combining the resources offered by a large multi-geography silicon organization with the startup culture and breadth of growth opportunities that working in a smaller ASIC team can provide. As a Physical Design Engineer, you will play a key role in the full RTL-to-GDSII implementation flow for advanced semiconductor nodes. You will optimize floor planning and timing, analyze and improve backend design flows, and collaborate across teams to ensure the successful delivery of high-performance networking chips. You will:

Responsibilities

Own and drive RTL-to-GDSII implementation for advanced nodes (sub-7nm to 2nm)
Define and execute hierarchical floor planning, place and route, clock and power distribution, and timing convergence strategies
Perform static timing analysis (STA), setup reviews, and sign-offs for multi-mode/multi-corner designs; develop automated scripts within STA tools
Implement and manage timing ECO strategies
Collaborate closely with RTL and DFT designers to debug and root-cause physical implementation issues related to design, tools, etc.
Evaluate and implement new timing methodologies; provide creative debugging solutions
Contribute to best practices and drive methodology alignment across projects
