Descriptions & RequirementsJob Description and Requirements What You'll Be Doing- Design and implement optimization techniques that reduce model calibration runtime without sacrificing accuracy, working directly with large-scale empirical datasets from leading-edge semiconductor processes
- Prototype and develop new mathematical models for lithography simulation, translating specifications into production-quality C++ code integrated into the Proteus product line
- Calibrate and tune complex non-linear model parameters using statistical analysis, numerical optimization, and domain-specific heuristics
- Collaborate with cross-functional teams including product engineering, field support, and customer-facing teams to understand technical requirements and integrate modeling solutions into existing workflows
- Analyze outlier data points and develop sampling strategies that improve model robustness and generalization across process variations
- Maintain and extend existing computational lithography models, diagnosing performance bottlenecks and correctness issues in a large, mature codebase
- Work directly with field engineers and customers to troubleshoot model behavior, gather requirements for new features, and validate solutions against real manufacturing data
The Impact You Will Have- Enable semiconductor manufacturers to bring next-generation nodes to production faster by delivering models that calibrate in hours instead of days
- Unlock previously unsolvable lithography challenges by developing optimization techniques that handle higher complexity and tighter tolerances than existing methods
- Improve model accuracy across a wider range of manufacturing conditions, reducing costly silicon respins and accelerating time to market for customers
- Strengthen Synopsys' competitive position in computational lithography by contributing novel algorithms and methods that differentiate the Proteus platform
- Reduce customer escalations and support load by building models that are more robust, interpretable, and easier to tune in the field
- Influence product roadmap and strategy by identifying technical gaps and opportunities based on direct customer interaction and data analysis
- Mentor and raise the technical bar for the broader modeling team by sharing deep expertise in optimization, numerical methods, and software engineering best practices
What You'll Need- PhD in Computer Science, Electrical Engineering, Physics, Applied Mathematics, or related field strongly preferred (recent PhD graduates encouraged to apply; PhD with 1-2 years of industry experience ideal), OR MS in a related field with approximately 5 years of directly relevant industry experience in computational modeling, optimization, or numerical methods
- Strong programming skills in C++ for performance-critical numerical software and Python for prototyping and data analysis
- Deep background in physical modeling, statistical analysis, and optimization methods, with hands-on experience applying these techniques to real-world problems
- Solid foundation in numerical computation, including experience with algorithms for solving non-linear systems, parameter fitting, and convergence analysis
- Demonstrated ability to analyze complex datasets, identify patterns and outliers, and translate findings into actionable model improvements
- Experience in computational lithography, optical modeling, or image processing is a strong plus
- Background working on large, complex software projects with multiple contributors and long product lifecycles is a strong plus
Who You Are- You can take a vague customer complaint about model accuracy, dig into the data, isolate the root cause, and propose a fix that addresses the underlying issue without breaking existing workflows
- You know when to optimize for speed and when to optimize for clarity, and you can defend that tradeoff to a senior engineer or a product manager without hand-waving
- You are comfortable presenting technical results to a mixed audience, whether that is walking a field engineer through a calibration workflow or explaining a convergence failure to a PhD researcher
- You do not get stuck when the data is messy or the requirements are incomplete, you make progress with what you have and course-correct as you learn more
- You care about the craft of writing maintainable code, not just code that works today, and you leave the codebase better than you found it
- You ask questions that cut to the core of a problem, and you listen carefully to the answers, especially when they come from people with different expertise than yours
The Team You'll Be Part OfYou will join the Proteus R&D team within the EDA Group, focused on computational lithography modeling for leading-edge semiconductor manufacturing. This is a collaborative, technically deep team working on problems at the intersection of physics, mathematics, and high-performance software engineering. The team works closely with cross-functional groups including product engineering, field support, and customers to deliver modeling solutions that enable next-generation chip manufacturing. You will have the opportunity to learn deeply within specific modeling topics while gaining broad exposure to new technologies across the computational lithography domain.
