About this role

Work Schedule Standard (Mon-Fri) Environmental Conditions Office Job Description Position Summary: The Senior Optical Engineer - Spectroscopy & Optical System, will contribute to the design, development and continuous improvement of Spectroscopy and optical system products. Working in a multidisciplinary engineering environment, you will collaborate closely with cross-functional teams to develop innovative electron optics solutions that deliver outstanding imaging performance, product quality and customer value with competitive cost. This position offers the opportunity to apply deep technical expertise in electron optics throughout the product development lifecycle, from concept development and system design to verification, product enhancement and sustaining engineering.

Key Responsibilities

Optical System Development Design, develop and optimize optical systems for spectroscopy and analytical instruments. Contribute to the development of optical subsystems including light sources, optical paths, mirrors, lenses, filters, beam splitters, monochromators, gratings, optical fibers and detectors. Support optical system integration across multiple spectroscopy platforms. Develop electron optics models, alignment methodologies, calibration procedures and verification approaches to support robust product performance. Optical Design & Analysis Perform optical design, tolerance analysis and performance optimization. Evaluate optical throughput, spectral resolution, wavelength accuracy, stray light, signal-to-noise ratio and overall optical performance. Develop optical alignment, calibration and verification methodologies. Support optical simulation and modeling using appropriate optical design tools Optical Integration Collaborate with electronics, mechanics, software and systems engineering teams to integrate optical subsystems into complete instruments. Support prototype integration, engineering verification and product validation. Investigate optical performance issues through laboratory characterization and Root Cause Analysis (RCA). Product Development Support new product development, product enhancement and sustaining engineering activities. Participate in design reviews, engineering documentation and continuous improvement initiatives. Contribute to reusable optical design methodologies and engineering best practices.

Qualifications

Basic Qualifications Bachelor's, Master's or Ph.D. degree in Optical Engineering, Physics, Applied Physics, Photonics or a related discipline.
