Senior Metrology Development Engineer

Apply Now
Join Rigaku in shaping a better world through new perspectives! We are seeking a Senior Metrology Development Engineer to develop data processing algorithms that integrate machine learning and physics simulations into our x-ray data processing pipelines, as well as build application engineer-focused data visualization and statistical analysis software. This role sits at the intersection of applications engineering and algorithm/software development, translating early-stage experimental concepts into robust, scalable data analysis solutions. The ideal candidate combines strong physics intuition, statistical/data science expertise, and practical software development skills to translate emerging metrology applications into robust algorithms and user-facing tools. Key Responsibilities: Algorithm Development: - Develop and prototype data analysis algorithms for X-ray metrology systems, including X-ray fluorescence (XRF) and X-ray diffraction (XRD). - Build Python-based proof-of-concept (POC) algorithms for spectral fitting, peak analysis, and quantitative materials characterization. - Collaborate with software engineers to productionize and integrate validated algorithms into scalable software pipelines. - Develop statistical and physics-informed approaches for improving measurement robustness, accuracy, and repeatability. - Develop robust methods for analyzing noisy, sparse, or high-dimensional experimental datasets, including uncertainty quantification and error propagation. Software Development: - Design and implement internal analysis tools that improve the efficiency of Applications Engineers. - Develop Python-based utilities for data exploration, visualization, and statistical analysis of metrology datasets. - Build lightweight tools, scripts, and dashboards that allow engineers to rapidly test new analysis approaches on experimental data. - Contribute to version-controlled codebases and collaborate with the software team to ensure maintainable, scalable implementations. - Write clean, modular, and well-documented code that can evolve from rapid prototypes into production-quality implementations. Machine Learning & Advanced Data Methods: - Explore and integrate machine learning and statistical modeling techniques for metrology data analysis. - Develop hybrid physics + data-driven models that enhance the interpretation of complex measurement data. Team Collaboration: - Partner with Applications Engineers to understand emerging customer applications and measurement challenges. - Work closely with physicists, materials scientists, and software engineers to bring new analysis methods from concept to deployment. - Document algorithms, analysis methods, and tools to support long-term maintainability and knowledge transfer. - Act as a technical bridge between applications engineering and software development, translating domain-specific problems into implementable algorithms and tools. Qualifications: Education & Experience: - Ph.D. or M.S. in Materials Science, Physics, Electrical Engineering, Data Science, or a related field. - Experience working with semiconductor process characterization or materials metrology data. - Demonstrated experience developing data analysis algorithms or scientific software for experimental datasets. - Experience translating experimental measurements into quantitative models and analysis pipelines. Technical Skills: - Strong programming experience in Python for scientific computing and data analysis. - Experience with scientific libraries such as NumPy, SciPy, Pandas, and visualization tools (Matplotlib, Plotly, etc.). - Experience developing data analysis pipelines and reusable codebases, not just one-off scripts. - Experience with curve fitting, optimization, or signal processing techniques. - Experience with version control (Git) and collaborative software development workflows (e.g., code reviews, branching strategies) Preferred Skills: - Experience with X-ray metrology techniques (XRF, XRD, XRR, or related methods). - Experience with machine learning frameworks. - Experience building data visualization dashboards or analysis GUIs for scientific workflows. - Experience developing tools that enable non-programmers to interact with complex datasets. - Background in semiconductor process development or failure analysis. - Japanese language proficiency (spoken and/or written) and experience collaborating with Japan-based engineering teams is strongly preferred.
