Principal R&D Engineer - Enterprise SerDes Physical Implementation

Category Engineering Hire Type Employee Job ID 18368 Base Salary Range €80000-€120000 Date Posted 08/19/2026

We Are

Synopsys is the leader in engineering solutions from silicon to systems, enabling customers to rapidly innovate AI-powered products. We deliver industry-leading silicon design, IP, simulation and analysis solutions, and design services. We partner closely with our customers across a wide range of industries to maximize their R&D capability and productivity, powering innovation today that ignites the ingenuity of tomorrow.

You Are

You have spent over a decade turning RTL into working silicon, and you know that the difference between a SerDes IP that meets spec and one that actually tapes out comes down to decisions made during floor planning, not during signoff. 

 You have taped out chips at 16nm or below. You write scripts because manual flows do not scale, and you speak timing signoff fluently enough to debug a failing path without waiting for translation. At Synopsys, you will work on 56G, 112G, and 224G PAM4/6 SerDes platforms that ship into real products.

What You'll Be Doing

• Drive physical implementation of high-speed SerDes IPs and test chips from RTL to GDSII, including timing closure and physical signoff
• Lead a small team of engineers through implementation flows, setting technical direction and clearing tapeout blockers
• Develop timing constraints and design architectures that meet power, area, and performance targets on TSMC 16nm and below
• Collaborate with front-end, analog, and CAD teams to resolve analog/digital interface challenges
• Automate implementation flows using Perl, Tcl, and Python across multiple process technologies
• Own chip-level integration and signoff for mixed-signal IPs before tapeout

The Impact You Will Have

• Your implementation decisions will determine whether SerDes IPs tape out on schedule and meet power and area targets
• The timing constraints you create will enable successful signoff across advanced process nodes
• Your leadership will accelerate the team's ability to deliver complex mixed-signal IPs without last-minute rework
• The automation you build will reduce manual effort and improve consistency across future projects
• Your technical judgment will shape how the team approaches low-power design and advanced node implementation
• The SerDes platforms you help deliver will power high-speed connectivity in AI, data center, and networking products worldwide

What You'll Need

• MSEE with 10+ years or BSEE with 12+ years in digital or physical design
• Experience leading physical implementation through multiple project tapeouts
• Deep knowledge of the full design cycle from RTL to GDSII, including chip-level integration
• Proven experience with TSMC 16nm or below, including low-power design techniques
• Strong scripting skills in Perl, Tcl, or Python with CAD automation experience
• Solid understanding of digital/mixed-signal verification flows and SOC integration
• Willingness to travel internationally as required

Who You Are

• You can spot the real bottleneck in a timing report and propose a fix that does not blow up area or power
• You push back on front-end teams if the RTL will create an unsolvable physical problem, and you can explain why
• You make decisions without waiting for perfect information because delay costs more than a well-informed judgment call
• You lead by setting clear direction and stepping in only when the team hits a blocker they cannot solve alone
• You treat automation as part of the job because you have seen what happens when manual flows meet tight schedules

The Team You'll Be Part Of

Your recruiter will share more about the team structure and mission during the interview process.
