Job description

We are LSP – Light Sensors & Photonics, one of three business units within ams OSRAM, advancing the digitalization of light. At LSP, we go beyond traditional sensing—combining light, silicon, and system expertise to enable digital photonics solutions. Our focus is clear: powering next-generation applications in data centers, AR/VR, mobile and automotive, where light becomes a critical interface for data, perception, and interaction. This evolution marks a shift from components to integrated photonics systems —driving performance, scalability, and innovation in high-growth segments.

Apply RF and analog design expertise to enhance the RF (radio frequency) immunity of optical sensor products, addressing interference challenges in sensitive optical sensor applications. Develop solutions to minimize RF signal interference, ensuring the performance of optical sensors used in consumer devices such as cellphones, smartwatches, laptops, and VR headsets. Work with interdisciplinary teams to integrate RF immunity features into optical sensor products. Overcome the challenges associated with designing high-sensitivity optical sensors that are sensitive to light and RF signal interference, ensuring reliable operation in the presence of diverse RF signals. Providing deep technical expertise in analog and RF circuit design, to create products with superior performance in challenging RF environments. Design advanced analog circuits and use advanced RF immunity design techniques to improve the sensor's RF immunity in harsh environments. Use 3D electromagnetic field modeling tools to extract block-, IC-, and package-level models, perform RF performance simulations, and optimize product performance using analog and RF circuit design techniques. Perform detailed transistor-level analog circuit design, including SPICE (Simulation Program with Integrated Circuit Emphasis) simulations, process/voltage/temperature (PVT) analysis, Monte Carlo simulations, and mixed-signal electrical simulations. Review block-level performance specifications and implement designs at the transistor level. Conduct block-level and top-level analog and RF simulations. Direct floor planning and layout activities in collaboration with the physical design team. Document circuit design solutions and performance summary reports for peer design reviews. Participate in circuit design reviews and collaborate with team members to share ideas and technical insights. Hybrid work policy w/in commuting distance.
