Virtual Analysis Engineer - Pistons & Rings

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. We’re turning today’s impossible into tomorrow’s 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 people as we aim to make driving 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 physics‑based 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 best‑practice definition across the organization.

What You'll 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 physics‑based simulation tools to evaluate design trade‑offs 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)

Bachelor’s 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)

Hands‑on 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., AVL‑based 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 late‑program 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 non‑technical stakeholders
