Multiphysics Modeling Engineer

Shape Your World

At Alcoa, you will become an essential part of our purpose: to turn raw potential into real progress.

The way we see it, every Alcoan is a work-shaper, team-shaper, idea-shaper, world-shaper.

At Alcoa, we’re reinventing the aluminum industry with innovation, integrity, and a commitment to sustainability.

Join our diverse and collaborative team at the Alcoa Technical Center (ATC), where your expertise will help develop groundbreaking technologies like ASTRAEA and ELYSIS—paving the way for a cleaner, more efficient future.

About the Role

As a Multiphysics Modeling Engineer, you will play a critical role in advancing our next-generation aluminum production and recycling technologies.

You’ll use advanced modeling techniques to simulate complex physical processes, support experimental design, and accelerate innovation.

In this role, the Multiphysics Modeling Engineer will:


* Numerically model physical processes using a range of modeling techniques ranging from deriving new and/or fundamental equations to using commercial Multiphysics software.


* Use aforementioned modeling techniques to:
+ Provide guidance to technology development, especially in early stages when we don’t have experimental data
+ Speed up the technology development process
+ Answer questions that cannot be answered experimentally
+ Understand and explain unexpected experimental results


* Perform data analysis from experiments to develop and validate computational models.


* Collaborate and interact with managers, co-workers, process engineers, and operations staff rather than isolating yourself from the team.  Learn from others and let them learn from you by regularly interacting with them.


* Observe equipment and operations in-person to get a hands-on understanding of the processes.


* Coordinate work with CAD designers in the iterative engineering process to find the efficient design as quickly as possible.


* Write technical reports and present findings of your modeling work to the broader team.  Seek out peer review of your work as a key step in the validation process.


* Speak up when key decisions are being made on which you have subject matter expertise.

What you can bring to this role:

Our values – act with integrity, operate with excellence, care for people, and lead with courage – are at the foundation of everything we do.

To be successful in this role the applicant should have the following background:

Minimum:


* PhD in Mechanical Engineering, Chemical Engineering, or related field.


* Fundamental understanding of the physical laws being solved in commercial multiphysics software.


* Single-physics modeling experience with all of the following: single phase flow, RANS turbulence, heat transfer (conduction, convection, and radiation)


* Single-physics modeling experience in at least one additional physics such as: species transport, electroc...
