• 4+ years of experience in physical design, with a focus on clock tree design and implementation. -
• Strong understanding of digital timing concepts, clock domain crossing, and synchronous/asynchronous design.
• Proficiency with EDA tools for CTS, STA, and physical verification (e.g., ICC2, Innovus, PrimeTime). -
• Experience with advanced nodes (e.g., 7nm, 5nm, 3nm) and FinFET technologies.
• Solid scripting skills (TCL, Python, Perl) for flow automation and data analysis. -
• Familiarity with low-power design techniques, including clock gating and multi-voltage domains.

Preferred Skills:

• Experience with custom clock tree architectures such as H-tree, mesh, or spine-based topologies. -
• Knowledge of EM/IR analysis, thermal-aware clocking, and reliability modeling.
• Exposure to high-speed interface clocking (e.g., SerDes, DDR, PCIe). -
• Understanding of package-level clock planning and signal integrity.

Principal Duties & Responsibilities:

Leverages advanced ASIC knowledge and experience to define, model, design (digital and/or analog), optimize, verify, validate, implement, and document IP (block/SoC) development for a variety of high performance, high quality, low power products.

Creates advanced architectures, circuit specifications, logic designs, and/or system simulations based on system-level requirements.

Collaborates across functional teams (e.g., software architecture, hardware architecture, product management, program management teams) to develop and execute an implementation strategy that meets system requirements and customer needs.

Evaluates all aspects of complex process flow from high-level design to synthesis, place and route, timing and power use, and verification or similarly for custom circuit design/layout flow.

Utilizes tools/applications (e.g., RTL to GDS Flow, Virtuoso) to execute and enable advanced architecture and design of multiple complex blocks/SoC or IC Packages.

Writes and reviews detailed technical documentation for complex EDA/IP/ASIC projects.

Level of Responsibility:

Works independently with minimal supervision.

Provides supervision/guidance to other team members.

Decision-making is significant in nature and affects work beyond immediate work group.

Requires verbal and written communication skills to convey complex information. May require negotiation, influence, tact, etc.

Has a moderate amount of influence over key organizational decisions (e.g., is consulted by senior leadership to make key decisions).

Tasks do not have defined steps; planning, problem-solving, and prioritization must occur to complete the tasks effectively.
