Principal I, Computational Modeling & Simulation Engineer will support the development, validation, and application of computational models and simulation methodologies for electronic and electromechanical systems used in medical devices. This role will focus on Signal Integrity (SI), Power Integrity (PI), electromagnetic analysis, and system-level Modeling to evaluate and optimize product performance, reliability, and robustness throughout the product development lifecycle. The engineer will work closely with electrical, mechanical, firmware, and systems engineering teams to leverage simulation-driven design approaches, reduce physical prototyping, accelerate development timelines, and support design verification and regulatory submissions. This role is on-site in our Lake Forest, CA location and a typical day would include: Perform Signal Integrity (SI) and Power Integrity (PI) analysis for high-speed digital interfaces, including DDR4, DDR5, MIPI, USB, and other high-speed communication protocols. Develop simulation models to evaluate channel performance, impedance discontinuities, crosstalk, timing margins, power delivery networks, and electromagnetic compatibility. Support simulation sign-off activities and provide design recommendations to improve electrical performance and robustness. Conduct pre-layout and post-layout analyses for PCB and package designs. Develop and validate electrical simulation models that predict system performance under varying operating conditions. Apply electromagnetic, circuit, and system-level simulation techniques to support product design optimization and risk reduction. Contribute to virtual prototyping initiatives to reduce design iterations and accelerate product development. Perform trade studies and sensitivity analyses to support engineering decision- making. Collaborate with hardware, firmware, systems, reliability, and manufacturing engineering teams to identify and resolve performance issues. Present simulation findings and design recommendations to technical stakeholders. Maintain complete and accurate documentation of simulation methodologies, assumptions, validation activities, and results. Follow applicable quality system requirements, SOPs, and GxP regulations. Support regulatory submissions and product verification activities through simulation-based analyses when appropriate. Support design reviews and verification activities with simulation-based evidence.
