R&D Engineering, Sr Engineer - Software Development

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're a hands-on software engineer who likes living close to the math and the physics — the kind of person who enjoys turning solver capabilities into something engineers can actually use. You care about clean design, but you also like shipping: building modules, wiring up APIs, writing tests, and iterating with QA and support when real-world issues show up. You're comfortable collaborating across disciplines — engineering, product, UX, and test — and you can hold your own in technical conversations about performance, parallelism, and correctness. You bring curiosity, persistence, and a practical approach to problem-solving. What You'll Be Doing Build and maintain software modules and subsystems that expose CPU- and GPU-based solver and post-processing capabilities in a multi-physics domain Collaborate with other R D engineers to design, implement, verify, and support simulation features end to end Develop on Windows using C++, C#/.NET, and related tools and technologies Create and maintain unit tests, APIs, and internal productivity tools to improve quality and developer velocity Investigate issues found by QA or product support, identify root causes, and deliver reliable fixes Apply software development best practices while working under the guidance of an R D manager The Impact You Will Have Help bring new simulation ideas and features to life by turning core solver capabilities into usable product experiences Improve product quality and stability through thoughtful design, test coverage, and disciplined debugging Enable faster development and smoother collaboration by building internal tools and well-documented APIs Support a product experience that feels immersive and intuitive by partnering closely with product management, UX, test, and other engineering teams What You'll Need Bachelor's degree in Engineering (or related field) plus 2+ years of experience, or a Master's degree in Engineering (or related field) Strong working knowledge of software design and development methodologies Strong C++ development experience Demonstrated problem-solving ability and persistence when working through complex technical issues Who You Are Comfortable learning new domains quickly and contributing in a team setting Clear communicator who works well with cross-functional partners Familiar with (or excited to grow into) C#/.NET development Interested in scientific computation, graphics engines, and numerical post-processing Grounded in object-oriented design, data structures/algorithms, and parallel programming concepts Experienced with professional development tools such as Visual Studio and Git Able to collaborate effectively with teammates in different locations and time zones Familiar with computer-aided engineering (CAE) software (a plus) The Team You'll Be Part Of You'll join an R D team focused on application development for computer-aided engineering software. The team works closely with product management, UX designers, testers, and other development groups to understand customer requirements and deliver simulation capabilities through an immersive, intuitive user experience — bringing new ideas and features to life in the Discovery product range. Rewards and Benefits Synopsys offers a comprehensive range of health, wellness, and financial benefits to support you and your family. We also provide a culture of continuous learning and development, global career opportunities, and a collaborative environment where you can do meaningful work alongside talented colleagues.
