Principal Modeling & Simulation Engineer

About the role

Alcon is seeking a Principal Modeling & Simulation Engineer to lead the development, validation, and application of computational models for electronic and electromechanical systems used in medical devices. The role focuses on Signal Integrity, Power Integrity, electromagnetic analysis, and system‑level modeling to optimize product performance throughout the development lifecycle.

Key responsibilities

• Perform Signal Integrity (SI) and Power Integrity (PI) analysis for high‑speed digital interfaces such as DDR4, DDR5, MIPI, USB, and other 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.
• Collaborate with hardware, firmware, systems, reliability, and manufacturing engineering teams to identify and resolve performance issues.

Required profile

• Bachelor’s Degree in Electrical Engineering or a related field, or equivalent experience.

Required skills

• Signal Integrity (SI) analysis
• Power Integrity (PI) analysis
• Electromagnetic compatibility (EMC) analysis
• High‑speed digital interface protocols (DDR4, DDR5, MIPI, USB)
• PCB and package design simulation
• Virtual prototyping and trade‑study techniques
