We design, develop, integrate, market and service these advanced machines, which enable our customers - the world’s leading chipmakers - to reduce the size and increase the functionality of their microchips, which in turn leads to smaller, more powerful consumer electronics. Our headquarters are in Veldhoven, the Netherlands, and we have 18 office locations around the United States including main offices in Wilton, CT, Chandler, AZ, San Jose, CA and San Diego, CA.\nJob Mission\nJoin a pioneering research team developing next-generation lithography light source technologies. Our laser-produced plasma (LPP) system integrates high-power lasers, advanced optics, plasma-based EUV generation, sensing, and algorithm-driven control. The Physics Informed Machine Learning Scientistworks on the Virtual Source team building integrated master-model frameworks to capture the tightly coupled, multi-physics behavior of the system-enabling system-level optimization, reducing uncertainty in future source configurations, and guiding early technology decisions. This role operates at the intersection of science, engineering, and modeling to define future source architectures. You will contribute by building data pipelines, developing data analysis and ML methodologies, integrating and advancing models, and defining validation experiments on test benches and research systems to anchor Virtual Source.\nKey Responsibilities:\nEstablish a scalable data management framework spanning legacy and new datasets from test benches and source prototypes, ensuring data quality, accessibility, and structured readiness for seamless integration into ML workflows.\n\nDevelop physics-informed machine learning models and scientific simulations to enable system-level tradeoff analysis and drive the definition and optimization of lithography source technology configurations.\n\nAdapt and integrate existing physics-based models into a master virtual model, and establish the necessary infrastructure for deployment and maintenance.\n\nPropose experimental anchoring studies, analyze test results, reduce model uncertainty through correlation building, and extract actionable knowledge from submodule- to full-system-level analysis.\n\nProvide input to technology roadmaps, identify de-risking activities and key scientific learning objectives, and contribute to experimental design to establish design guidelines, performance requirements, and procedures for product teams.\n\nTroubleshoot code and algorithms required for source operation, data streaming, storage, and queries.\n\nDocument learnings and communicate knowledge to engineering and product development teams to guide product improvement and the release of new product nodes.\n\nWork independently and collaboratively to deliver on stated objectives, whether pursuing new knowledge, demonstrating new capabilities, or characterizing existing performance.\n\nPerform other duties as assigned or required.\n\nQualifications\nPh.D. with a minimum of 3+ years of experience or a Master’s degree with at least 6+ years of experience in an analytical field such as mathematics, physics, or engineering, with extensive experience in physics-informed machine learning and model integration into scalable master models.\n\nExperience solving complex, open-ended modeling problems using optimization and deep learning methodologies, with strong expertise in data management and building scalable data and training pipelines for end-to-end model development and training.\n\nStrong software development skills in Python, with experience in deep learning frameworks (e.g. PyTorch or JAX); proficiency in C/C++, and Matlab is a plus. Experience with database tools, automation frameworks, and experimental tracking platforms (e.g. MLflow) for managing end to end ML lifecycle.\n\nExperience working in cloud and development environments such as Azure Kubernetes Service (AKS), Google Distributed Cloud Edge (GDCE), Apache Spark, Azure Databricks, and related technologies is a plus.\n\nSkills\nAbility to clearly and logically communicate ideas and knowledge to various audiences.\n\nDemonstrated ability to work effectively as a part of a team and lead investigation and research efforts involving multiple stakeholders and constraints.\n\nProven ability to build trust and credibility, enabling effective leadership through influence.\n\nThe successful candidate will not only have excelled in their technical field, but will have demonstrated inter-personal and communications strengths.\n\nDeep understanding of scientific research methods and strong curiosity.\n\nOther information\nPHYSICAL DEMANDS AND WORK ENVIRONMENT\nThe physical demands described here are representative of those that must be met by an employee to successfully perform the essential functions of this job.
