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
