About the job
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 years in the trenches of timing signoff, and you know the difference between a clean sign-off and one that comes back to haunt you three weeks before tapeout. You understand that static timing analysis is not just about running PrimeTime, it is about understanding what the silicon will actually do when variation, IR drop, temperature, and aging all hit at once. You have debugged enough false paths and multi-cycle exceptions to know when a constraint deck is solid and when it is held together with hope. You are equally comfortable sitting with an R&D architect discussing distributed STA algorithms and walking a customer's design team through a HyperGrid deployment that just cut their runtime by 40%. When a strategic account hits a blocker two weeks before their signoff milestone, you are the person they call because you will find the path through, whether that means a creative workaround, a targeted fix, or a hard conversation about what is actually achievable. You do not just react to problems, you see them coming. You connect dots between what customers are struggling with today and what the product roadmap needs to solve tomorrow. At Synopsys, you will shape the future of timing signoff for the designs that power everything from data centers to mobile devices. What You'll Be Doing Drive production deployment of PrimeTime capabilities including HyperGrid distributed STA, native IR-aware timing analysis, thermal-aware signoff, aging analysis, and multi-die timing closure at strategic semiconductor customers Lead direct technical engagements with design teams at leading-edge accounts, translating their advanced-node challenges into concrete product requirements, deployment strategies, and success metrics Partner with R&D teams to evaluate new architectures like cloud-native PrimeTime and AI-assisted constraint generation, validating functionality, identifying performance bottlenecks, and driving resolution of complex product issues Own beta programs and pre-production evaluations from kickoff through production readiness, defining test plans, tracking results, and ensuring customer success criteria are met Resolve critical customer escalations through structured root-cause analysis, building effective workarounds when needed and driving long-term fixes back into the product Translate deployment experience, competitive intelligence, and customer feedback into clear roadmap recommendations for Product Management and engineering leadership Create technical content including deployment guides, best-practice methodologies, executive briefings, and training materials that accelerate adoption across the field organization and customer base The Impact You Will Have Enable customers to achieve timing signoff on designs that would otherwise miss their tapeout windows, directly affecting product launch schedules for chips powering AI, automotive, and mobile applications Shape the PrimeTime roadmap by connecting real customer pain points with engineering priorities, ensuring development resources focus on capabilities that will drive the most adoption Accelerate time-to-production for next-generation capabilities like ML-based corner optimization and automated SDC generation, turning research concepts into deployed solutions Build reusable deployment methodologies that scale across the customer base, turning one successful engagement into a repeatable playbook Strengthen Synopsys competitive position in timing signoff by ensuring customers see measurable value from advanced features before competitors can catch up Mentor Application and Product Engineers across the organization, raising the technical bar and building institutional knowledge around complex signoff challenges Influence the architecture of future PrimeTime releases by representing real-world deployment constraints and customer workflows in early design discussions What You'll Need BS or MS in Electrical Engineering, Computer Engineering, Computer Science, or related technical discipline Deep hands-on experience with PrimeTime or comparable timing signoff tools across multiple production tapeouts, including multi-corner multi-mode analysis, variation modeling, and advanced-node signoff challenges Strong understanding of static timing analysis fundamentals including setup/hold analysis, clock domain crossing, false paths, multi-cycle paths, and constraint methodology Proficiency in Tcl and Python for automation, analysis, and debugging of complex timing scenarios Track record of solving hard technical problems in EDA, ASIC/SoC design, or physical implementation environments where the answer was not obvious and the stakes were high Experience with distributed computing, cloud infrastructure, or HyperGrid technologies is a strong plus Background deploying new EDA technologies at semiconductor companies, including managing beta programs, customer training, or production readiness activities is highly valued Who You Are You can walk into a room where a customer's timing closure is stuck and within an hour identify whether the issue is in their constraints, their methodology, the tool, or their design, and you know how to have that conversation without pointing fingers When R&D proposes a new algorithm, you immediately think about how it will behave on a real customer design with 500 modes, 200 corners, and a constraint deck that has evolved over three years You write Tcl and Python that other engineers can actually read and modify six months later, because you know that one-off scripts become production infrastructure You can explain a complex timing analysis tradeoff to a VP in two sentences without losing the technical nuance, and you can turn around and debug a multi-threaded race condition with an engineer the next hour When you commit to a customer delivery date or an internal milestone, people know it will happen because you build in contingency and you escalate early when something is at risk You push back when a product plan does not account for real deployment complexity, and you do it in a way that moves the conversation forward rather than shutting it down The Team You'll Be Part Of You will join the PrimeTime Product Engineering team, working at the intersection of R&D, Product Management, and customer-facing Application Engineering. This team drives the technical strategy and production readiness for Synopsys timing signoff solutions, which are used by every major semiconductor company to sign off chips ranging from mobile processors to data center accelerators. Your work will directly influence both the product roadmap and how customers deploy PrimeTime across their most critical design programs. Rewards and Benefits We 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.
