ASIC Digital backend Physical Implementation Engineer

As the global leader in high-speed connectivity, Ciena is committed to a people-first approach. Our teams enjoy a culture focused on prioritizing a flexible work environment that empowers individual growth, well-being, and belonging. We’re a technology company that leads with our humanity—driving our business priorities alongside meaningful social, community, and societal impact.

How You Will Contribute:

Ciena’s WaveLogic family of products is a cornerstone of our optical fiber transmission solutions, driving innovation and success in the telecommunications industry. As a Digital ASIC Physical Implementation Engineer, you will play a critical role in developing large mixed-signal SoC ASICs targeting advanced technology nodes. Your contributions will directly impact the performance, power efficiency, and area optimization of our industry-leading WaveLogic ASICs.

In this role, you will:

• Scope and define the physical architecture of designs, utilizing EDA vendor tools to build, adapt, and maintain a robust flow from netlist to full closure and GDSII generation.
• Partner with RTL circuit designers and other layout engineers to create optimal floorplans, design power grids, and clock distribution networks that achieve the best performance and power efficiency.
• Navigate and fine-tune EDA tool settings, parameters, and attributes to ensure signoff-quality results with an optimal balance of performance, power, and area (PPA).
• Identify and propose alternative implementations, trade-offs, and solutions to achieve lower power consumption and higher performance.
• Collaborate with analog designers and ASIC/SoC teams to integrate analog blocks seamlessly into the overall design.
• Conduct initial Place & Route trials to refine design and correlation, influencing circuit architecture by working closely with RTL designers and architects to ensure reliable and closable physical design.
• Generate and implement timing ECOs to achieve timing closure, as well as functional ECOs to address RTL feature fixes when necessary.
• Utilize tools like Formality or Conformal for formal verification, analyzing reports and ensuring design accuracy and integrity.
• Write scripts to enhance productivity and efficiency for yourself and other backend engineers. Collaborate with tool and technology vendors to drive fixes, improve workflows, and evaluate new tools and features.
• Produce concise status reports at various stages of development, highlighting trade-offs and providing actionable insights.
• Understand and implement Design for Test (DFT) requirements provided by the ASIC service provider. Use physical-aware synthesis features to mitigate timing issues associated with layout and/or  ECOs.
• Resolve timing challenges associated with DFT through scan chain reordering, placement, and CTS constraints.
• Run Static Timing Analysis (STA), analyze timing reports, and debug issues related to timing constraints, missing exceptions, and tool correlation between P&R and STA tools, ect.
• Your expertise in physical design, collaboration with cross-functional teams, and ability to innovate will be instrumental in advancing Ciena’s cutting-edge optical networking solutions.

The above lists are intended to describe the general nature and level of work, and they are not intended to be a comprehensive list of all responsibilities, duties and skills required to be qualified and to be performed by the selected candidate. You will have an opportunity to better understand the role through the interview experience.

What Does Ciena Expect of You:

• Sense of urgency and accountability – what’s important to the customer is important to you; you make getting things done a priority.
