Thermal-Mechanical Power Electronics Applications Engineer

Ansys; España; On-site; EUR 70,000 - 100,000; Full time

Job summary

Ansys is seeking a highly experienced engineer to lead advanced electro-thermal and reliability simulations for power electronics within the Synopsys ecosystem. You will design die-to-board multiformat workflows, tackle complex thermal-electrical coupling, and drive customer value through rigorous technical evaluations.

You will collaborate across engineering and product teams, develop best practices, and contribute to materials, case studies, and trainings that showcase ROI and reliability

Qualifications

• 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
• Proficiency in Python for scripting, automation, and workflow integration; AI/ML experience in 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
• Willingness to travel domestically and internationally up to 25% of the time

Responsibilities

• 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
