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.\nYou Are\nYou have spent years deep in the trenches of transistor-level power integrity and EM/IR signoff, solving complex problems that can directly impact a customer's tapeoutschedule. You understand what it takes to analyze challenging IR drop and electromigration issues, identifytheir root causes, and drive them toward practical resolution. You know the difference between a methodologythat works on paper and one that holds upin real-world analog, mixed-signal, ESD, and high-speed interface designs. You recognize patterns before they become critical signoff problems, and you are the engineer customers trustwhen complex power integrity and EM/IR challenges put their signoff schedule at risk.\nYou do not just answer questions. You help engineers understand how to approach power integrity and EM/IR problems systematically and build the confidence to solve them. Mentoring a junior engineer through a complex IR drop analysis or walking a customer's design team through a new signoff flow feels as important to you as solving the technical problem itself. You move comfortably between deep technical investigation and strategic customer conversations, and you know when to dig deeper yourself, collaborate across teams, or escalate toR&D to drive an issue toward resolution.\nAt Synopsys, you will work with customers pushing the limits of advanced nodes, multi-die integration, and custom IC design. The problems are real, the stakes are high, and what you build and teach will shape how teamssignofftheir most critical designs.\nWhat You'll Be Doing\nOwn technical relationships with assigned customer accounts, serving as the primary technical contact for Totem and Totem-SC engagements, driving adoption, methodology development, and issue resolution\nLead transistor-level power integrity and EM/IR signoff work across analog, RF, ESD, embedded memory, and high-speed interface designs, helping customers analyze complex design issues, validate results, and establish robust signoff methodologies.\nDevelop, validate, and optimize customer signoff flows for advanced nodes and 3DIC designs, including scripting in Python, Tcl, Perl, or Shell to automate workflows and improve scalability\nDrive complex technical investigations from initial customer reports through root-cause analysis and resolution, coordinating with R&D and internal teams to deliver technically sound and sustainable solutions.\nLead technical evaluations, benchmarks, workshops, and training sessions, partnering with Sales to expand product adoption and identify growth opportunities\nMentor applications engineers on signoff methodology, power-integrity analysis, and customer engagement, establishing reusable best practices and technical standards\nCollaborate with Product Management and R&D to influence product roadmap based on real customer use cases, technical gaps, and emerging signoff requirements\nThe Impact You Will Have\nEnable customers to successfully tape out advanced node and 3DIC designs by delivering robust, scalable power integrity and EM/IR signoff methodologies\nReduce customer time-to-signoff through automation, scripting, and workflow optimization that directly improves engineering productivity\nAccelerate Totem and Totem-SC adoption across new customer accounts and design teams, expanding the technical footprint and business impact\nImprove product quality and capability by surfacing real customer issues, use cases, and methodology gaps that shape R&D priorities\nBuild technical expertise across the applications team through mentorship, documentation, and knowledge transfer that raises the bar for everyone\nStrengthen customer trust and retention by consistently delivering expert guidance, fast resolution, and methodologies that work under pressure\nDrive competitive differentiation by establishing Synopsys as the trusted partner for transistor-level signoff in the most demanding design environments\nWhat You'll Need\nBachelor's or Master's in Electrical Engineering, Electronics Engineering, or equivalent practical experience\nTypically10 or more years in semiconductor EDA, IC design, or applications engineering, with substantial customer-facing technical experience\nProven ability to independently manage technical engagements, customer expectations, and escalations from first contact through resolution\nStrong hands-on experience with transistor-level EM/IR, power-integrity, power-grid extraction, or related signoff solutions; direct Totem or Totem-SC experience is a plus\nSolid understanding of analog and custom IC design, circuit analysis, physical layout, and semiconductor signoffmethodology\nFamiliarity with semiconductor design data and EDA flows, including SPICE netlists, SPEF, DSPF, and layout databases\nProficiency in UNIX/Linux environments and at least one scripting language such as Python, Tcl, Perl, or Shell\nExperience in analog/RF, ESD, embedded memory/IP, or high-speed interface design is a plus\nExperience with 3DIC, multi-die integration, or associated power-integrity and signoff flows is a plus\nFamiliarity with advanced semiconductor technologies, including FinFETand GAA, is a plus\nExperience applying AI, machine learning, LLMs, or agent-based automation to engineering productivity, technical support, data analysis, or EDA workflows is a plus\nWho You Are\nYou can walk into a customer meeting with incomplete data, ask the right questions, and leave with a clear technical plan that everyone believes in\nYou know when a problem needs a quick workaround to unblock a tapeoutand when it needs a deeper methodology fix, and you are comfortable making that call\nYou can explain a complex power integrity or EM/IR signoff issue to a customer's VP in two sentences without losing the nuance, then work side by side with their engineers to investigate the technical details and drive the problem toward resolution.\nYou do not wait for someone else to write the documentation or build the training deck, you create what is missing because you know it will make the next engagement smoother\nYou treat mentoring as part of the job, not an extra, and you get energy from watching someone else solve a problem you helped them think through\nYou are comfortable with occasional domestic or international travel when a critical customer engagement or business need requires your presence\nThe Team You'll Be Part Of\nYour recruiter will share more about the team structure and mission during the interview process.\nRewards and Benefits\nWe offer a comprehensive range of health, wellness, and financial benefits to cater to your needs. Our total rewards include both monetary and non-monetary offerings. Your recruiter will provide more details about the salary range and benefits during the hiring process.\nAt Synopsys, we want talented people of every background to feel valued and supported to do their best work.
