Job Description and Requirements

We Are

At Synopsys, we're shaping the future of innovation from silicon to systems.

Building on decades of leadership in semiconductor design and electronic systems, the addition of ANSYS brings together world-class expertise in simulation, analysis, and engineering solutions. Together, we empower customers to design, test, and optimise everything from advanced semiconductor technologies and AI-powered systems to autonomous vehicles, aerospace platforms, industrial equipment, and next-generation products.

By combining industry-leading silicon design, IP, simulation, and digital engineering technologies, we help organisations accelerate innovation, reduce development risk, and bring breakthrough products to market faster.

Together, we're enabling the innovations that will define tomorrow.

You Are

You know power devices from the inside out: how they are built, packaged, and used, and more importantly, how they fail. Maybe you came up through thermo-mechanical reliability engineering, or maybe you spent years designing power devices and power electronics. Either way, you understand that simulation is not about running tools, it is about asking the right question at the right stage and trusting the answer enough to act on it.

Every load cycle is a temperature swing. Every swing stresses the hardware. CTE mismatch drives solder fatigue, wire bond lift-off, and delamination, and you have learned to turn mission profiles into lifetime predictions that actually hold up on the test bench. You treat electrical, thermal, and mechanical behaviour as one coupled problem because you have seen electrically optimal designs fail in the field when someone ignored the physics.

You can walk into a room with a customer's engineering team, quickly understand their device technology, packaging constraints, and reliability targets, then map a simulation strategy that fits their workflow. Strong opinions about application engineering come naturally to you. You push back on fragile workflows, on feature requests that miss the real problem, and on treating reliability as an afterthought.

What You'll Be Doing

• Shape customers' simulation strategies by partnering with senior power electronics teams to understand their roadmaps, reliability goals, and constraints, then define workflows aligned with their design processes
• Build die-to-board Multiphysics workflows that couple electrical, thermal, and structural analysis across the substrate, package, and PCB to predict hotspots, warpage, and interconnect fatigue before they reach the lab
• Drive thermal-mechanical reliability by turning mission profiles into junction temperature cycling, predicting solder fatigue, wire bond lift-off, and delamination, and correlating the results with power cycling and test data
• Prove value on real designs by leading technical evaluations and benchmarks that show measurable impact, not just impressive demos
• Be the voice of the customer by challenging fragile workflows, bringing R&D feature requests grounded in real problems, and helping shape the product roadmap
• Scale expertise by creating best practices, application notes, and training materials that help customers and colleagues get more out of the tools
• Support field and digital marketing by contributing to technical content, customer case studies, and industry events focused on thermal-mechanical and reliability for power semiconductor applications

The Impact You Will Have

• Enable customers in data centre power delivery, electric vehicle powertrains, and renewable energy systems to accelerate their product development cycles and improve performance metrics through better simulation workflows
• Drive adoption and expansion of Ansys solutions across the power electronics segment by proving technical value in real customer design environments
• Shape the product roadmap for power electronics simulation by channelling deep customer insight and application requirements back to engineering teams
• Build repeatable, scalable workflows that become the standard methodology for electrothermal, thermomechanical, and reliability simulation in power module and PMIC design
• Reduce time-to-revenue for strategic accounts by solving technical blockers, proving ROI, and ensuring customers can deploy and scale Ansys tools independently
• Contribute to the long-term growth of the Ansys business within Synopsys by turning technical wins into commercial momentum and customer loyalty

What You'll Need

• MS or PhD in Electrical Engineering, Computer Science, or related field, or BS with 5+ years of professional experience in an engineering software or power electronics design environment
• Subject matter expertise in power electronics, ideally with industry experience in power converters, power modules, or power management ICs structural mechanics and reliability
• Demonstrated use of commercial EDA or CAE software such as circuit simulators, electromagnetic field solvers, or thermal/mechanical reliability tools in a professional or research setting
• Proficiency in Python for scripting, automation, and workflow integration. Experience applying AI/ML or agentic AI to engineering simulation is a strong plus
• Comfort working in Linux environments and navigating complex multi-tool simulation flows
• Fluency in English, both written and spoken, with the ability to communicate complex technical tradeoffs clearly to engineers and executives
• Willingness to travel domestically and internationally up to 25% of the time, with flexibility to increase travel as customer engagements require

Who You Are

• You do not wait for perfect documentation or a complete dataset. You work with what you have, fill gaps through smart questions, and move forward without creating chaos downstream
• You are organized enough to juggle multiple customer evaluations, a product beta test, and a conference presentation without dropping threads, and you know when to escalate or ask for help

• You have the technical credibility to challenge a customer's assumptions or a product team's feature priority when you see a better path, and you do it in a way that builds trust instead of friction
• You treat every customer's engagement like it matters because you know that a good technical win this quarter turns into a long-term partnership, and a bad handoff turns into churn
• You are comfortable presenting to senior engineering managers and C-level executives, translating simulation results and workflow improvements into business outcomes they care about

The Team You'll Be Part Of

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

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.

At Synopsys, we want talented people of every background to feel valued and supported to do their best work. Synopsys considers all applicants for employment without regard to race, color, religion, national origin, gender, sexual orientation, age, military veteran status, or disability.
