## Description

NVIDIA is looking for a Senior Thermal Engineer to lead thermal design and evaluation for next-generation photonic built circuits and built optical modules (CPO) platforms.

In this position, you will address sophisticated electro-thermal and multi-physics problems at the chip, package, and system scales, supporting high-density, high-performance optical-electrical integration. You will collaborate with teams in photonics, electrical IC, packaging, and reliability.

Responsibilities:

- Engineer, construct, and optimize thermal solutions for silicon photonics and co-packaged optics systems, involving closely aligned optical engines and ASICs.

- Develop and examine comprehensive thermal models using Cadence Celsius Thermal Solver, investigating temperature-dependent characteristics of photonic devices.

- Drive thermal co-design and optimization of co-packaged architectures, including heat sinks, cold plates, and thermal interface materials (TIMs).

- Model and simulate heat transfer and airflow using advanced CFD tools to enable scalable, high-efficiency cooling solutions.

- Lead simulation-to-silicon correlation, contributing to experimental validation, thermal characterization, and root-cause analysis.

- Define and influence thermal build methodologies and guidelines for next-generation optical interconnect and high-performance computing systems.

Requirements:

- PhD in Mechanical Engineering or a related field (or equivalent experience) with 4+ years of proven experience in thermal or mechanical engineering.

- Deep expertise in Cadence Celsius Thermal Solver, CFD tools, coupled electro-thermal simulation, and thermo-mechanical stress analysis.

- Strong fundamentals in heat transfer, thermodynamics, and proven mechanics.

- Proficiency in Python or MATLAB for modeling, automation, and data analysis.

- Proven track record to collaborate efficiently in fast-paced, multi-functional engineering teams.

- Experience with silicon photonics, optical interconnects, or datacenter hardware would be considered a plus.

Benefits:

- Equity
