The Senior Optical Engineer will contribute to defining optical system requirements and concepts and will work closely with Electrical Engineering, Mechanical Engineering and Test Engineering throughout the product development process.\nThe role also involves close collaboration with external engineering partners, contract manufacturers and suppliers, particularly in Asia, to translate optical system concepts and specifications into robust, manufacturable solutions.\nEssential Functions\nDefine and develop optical system requirements based on product and system requirements.\nDevelop and evaluate optical concepts for imaging, illumination and vision systems.\nSpecify, design and qualify optical components and subsystems and provide optical engineering support during pre-production builds.\nProvide system-level optical expertise throughout the product development lifecycle and ensure the effective integration of sensors, lenses, lighting, filters and related components.\nCollaborate closely with Electrical Engineering, Mechanical Engineering and Test Engineering to develop integrated solutions.\nDefine and recommend optical test methods, qualification approaches and acceptance criteria in cooperation with Test Engineering.\nAnalyze and troubleshoot complex product and system issues where the root cause may be related to optical design or system integration.\nWork with external engineering partners, contract manufacturers and suppliers on the design, development and manufacturability of optical components, subsystems and assemblies.\nProvide technical direction and specifications to suppliers and partners and support the successful implementation of optical system concepts into production-ready solutions.\nEvaluate new technologies, components and technology partners and contribute to innovation and future product concepts.\nBalance optical performance, manufacturability, cost, quality and scalability when developing solutions for high-volume products.\nKnowledge, Skills and Abilities\nStrong understanding of optical and machine vision systems and the interaction between sensors, lenses, illumination, filters and other optical components.\nAbility to approach optical challenges from a system perspective and quickly connect technical dependencies across multiple engineering disciplines.\nStrong ability to develop optical concepts from underdefined requirements and translate them into clear technical specifications.\nAbility to perform first-order calculations and create initial optical system concepts for imaging and illumination applications.\nExperience with optical design and simulation tools such as Zemax and/or LightTools.\nExperience with 3D CAD software, preferably SolidWorks, is beneficial.\nKnowledge of lenses, mirrors, LEDs, visible diode lasers, CMOS sensors, optical filters and coatings.\nExperience working with external engineering partners, suppliers or contract manufacturers, ideally in an international environment.\nStrong problem-solving and analytical skills with the ability to independently drive complex technical topics.\nStrong communication and collaboration skills and the ability to work effectively across multidisciplinary and international teams.\nCreative and innovative mindset with a strong interest in developing high-performance machine vision products that can be manufactured cost-effectively and at scale.\nMinimum Education and Work Experience Required\nUniversity degree in optics, optical engineering, physics or a related engineering field.\nRelevant professional experience in optical engineering, optical systems, machine vision or a related field.\nDemonstrated experience working on complex optical or vision systems from concept and specification through development and qualification.\nExperience working in multidisciplinary product development environments.\nCandidates with less professional experience but an outstanding academic track record, strong technical capabilities and demonstrated potential are also encouraged to apply.\nAdditional Job
