Virtual Analysis Engineer Pistons & Rings

Job Description

At General Motors our product teams are redefining mobility. Through a human-centered design process we create vehicles and experiences that are designed not just to be seen but to be felt. Were turning todays impossible into tomorrows standard from breakthrough hardware and battery systems to intuitive design intelligent software and next-generation safety and entertainment features.

Every day our products move millions of peopleas we aim to makedriving safer smarter and more connected shaping the future of transportation on a global scale.

The Role

The Virtual Analysis Engineer Pistons & Rings is a senior technical individual contributor responsible for advanced virtual analysis development support and hardware release activities for internal combustion engine piston and piston ring systems. This role applies deep physicsbased understanding to ring dynamics blowby and lubricating oil consumption translating simulation results into actionable engineering and program decisions.

This position operates with significant autonomy serves as a technical authority within its domain and contributes to method development tool validation and bestpractice definition across the organization.

What Youll Do

• Lead and execute advanced virtual analysis of piston and piston ring pack behavior including:
  • Blowby and sealing performance
  • Lubricating oil consumption mechanisms
  • Ring dynamics (conformability twist flutter and gas dynamics)
• Apply physicsbased simulation tools to evaluate design tradeoffs and support engine program decisions
• Support hardware release validation and issue resolution including:
  • Correlation of analytical predictions to engine test data
  • Interpretation of teardown results and field feedback
• Independently define modeling approaches assumptions and boundary conditions appropriate to program needs
• Serve as a technical interface with design test manufacturing and supplier teams
• Contribute to continuous improvement of analysis methods workflows and standards
• Provide technical guidance and informal mentoring within the piston and ring analysis community

Your Skills & Abilities (Required Qualifications)

• Bachelors degree in Mechanical Engineering or related discipline
• 5 years of experience in:
  • Internal combustion engine piston and piston ring analysis or development
  • Blowby and lubricating oil consumption modeling
  • Hardware release or validation support
• Strong understanding of:
  • Piston secondary motion
  • Tribology and lubrication fundamentals
  • Gas dynamics related to ring pack sealing
• Demonstrated ability to translate virtual analysis results into clear engineering recommendations

What Will Give You A Competitive Edge (Preferred Qualifications)

• Handson experience with MIT Consortium piston and ring analysis tools
• Experience using Realis RINGPAK for development or production programs
• Exposure to commercial CAE tools (e.g. AVLbased solutions) or internally developed analysis codes
• Advanced degree (MS or PhD) focused on engines tribology or applied mechanics
• Prior ownership of piston or ring system design decisions through production release
• Experience supporting lateprogram issues launch or warranty investigations
• Recognized technical depth in piston and ring system virtual analysis
• Works independently on complex ambiguous engineering problems
• Influences technical direction across multiple programs or platforms
• Balances model fidelity assumptions and hardware reality
• Communicates complex physics clearly to both technical and nontechnical stakeholders
