This position requires an employee to be onsite 1-3 times per week.
Perform solar load and thermal dimensional stability assessment on exterior components and systems. Knowledge of non-linear thermal behavior for plastic parts. Knowledge of creep and pre-stress phenomenon in plastic parts. Understand metal, plastic and composite material behavior when subjected to solar and thermal loading and perform CAE evaluations. Perform structural analysis on exterior components and sub-systems such as: bumpers, fascias, grilles, luggage racks, assist steps, moldings, spoilers, and exterior lighting. Use
Finite Element Analysis (FEA) and other analysis methods to assess component designs. Analysis is focused on design optimization to meet safety regulations (low speed bumper regulations) and customer usage. CAE Engineers work interactively with the Product Development Teams (PDT's) to share analysis results, provide design recommendations, and assure that product requirements are met.
Primary Responsibilities:
  • Responsible to create and execute solar and thermal loading analysis methodologies and approach on exterior parts - plastic and composite.
  • Interface with SMT and validation to lead simulation capability and assess performance.
  • Responsible to create and execute Finite Element Analysis (FEA) plans for assigned projects. Lead CAE suppliers and internal resources to meet program milestones and deliverables.
  • Create CAE geometry or construct / update FEA models from NX math data. Debug 1st run vehicle structure models from suppliers (external and internal).
  • Perform and coordinate resources for virtual assessment of designs and compare results to performance requirements.
  • Recommend viable design solutions to resolve any performance issues with mass & cost efficiency.
  • Interface with SMT, validation, aero, structure integration, N&V, and safety integration engineers to assure balance of vehicle structure requirements and design solutions.
  • Conduct topology optimization to identify architectural load paths to close the gap to requirements and implement enablers into the math released.
  • Plan and implement test and/or development programs to enhance CAE capability.
  • Recommend process automators and CAE enhancements for CAE modeling software and solvers. Assist in developing new CAE techniques.
  • Use CAE to explain results of physical testing and engineer solutions to resolve issues with validation and release engineers.

An Insider's view of General Motors

How would you describe the company’s work-life balance?

GM has a people-first culture that inspires everyone to help each other and improve themselves. It fosters a workplace of inclusivity instead of focusing solely on company results. I really feel like I am seen as an individual and that my work has an impact at GM.


Data Analyst, Data Management and Analytics Group

What projects are you most excited about?

I’m currently working on the Cruise AV and Cruise Origin, along with ADAS projects. I enjoy working in the new technology space because it allows me to think creatively and come up with innovative ideas to solve problems.

The key to success is understanding the business while building and growing your leadership acumen.


Program Engineering Manager, Battery Electric Vehicles

How do you make yourself accessible to the rest of the team?

I want my team members to feel like they’re working with me, not for me. So, I make myself vulnerable to my team. I share my failures and ask for help. Likewise, I try to create an open, safe and trusted environment for them to discuss their challenges. I share my success stories to inspire them to realize their career aspirations.


Director, Ultifi Data Platform Services

How has your career grown since starting at the company?

I started as a calibration test engineer, then moved into our Immersive Lab, where I leveraged cutting-edge technology to speed up engineering and design processes. Now, I’m using that experience as an Integration Design Engineer in our Advanced Studio. These opportunities enabled my professional growth and I can’t wait for my future in innovation.
