We are seeking a highly experienced and technically authoritative Chief Mechanical Engineer – Automotive Valvetrain to lead the design, development, and validation of valvetrain systems for internal combustion engines across automotive platforms. This role will serve as the technical expert and decision-maker for all aspects of mechanical valvetrain architecture including camshafts, followers, tappets, valves, valve actuation systems (mechanical, hydraulic, electro-hydraulic), and timing drives.
The ideal candidate will ensure that valvetrain systems meet performance, durability, NVH, emissions, and cost objectives, and will guide a team of engineers through detailed development, from concept to production launch.
Lead the architecture, conceptual design, and optimization of complete valvetrain systems.
Select appropriate technologies: DOHC/SOHC, VVT (Variable Valve Timing), VVL (Variable Valve Lift), hydraulic lash adjusters, cam phasers, etc.
Ensure design alignment with engine performance goals, emissions compliance, fuel efficiency, and cost constraints.
Direct and approve 3D designs, tolerance stacks, and detailed drawings of valvetrain components.
Oversee simulation activities (e.g., dynamic valve train analysis, stress/strain, fatigue, and thermal expansion).
Guide analysis using FEA, MBD (Multi-Body Dynamics), and analytical modeling tools.
Ensure compatibility and integration with cylinder head, lubrication system, and timing drives.
Lead the planning and execution of DVP&R (Design Verification Plan and Report), including rig testing, engine dyno, and vehicle-level validation.
Conduct root cause analysis and implement design improvements based on testing, warranty data, and customer feedback.
Collaborate with combustion and performance engineers, cylinder head designers, controls teams, and NVH specialists.
Align with manufacturing, quality, and sourcing teams to ensure design feasibility and supply chain readiness.
Interface with OEM clients or internal platform teams on technical reviews, gate approvals, and design sign-offs.
Mentor junior and mid-level engineers in mechanical design, engineering standards, and problem-solving.
Set engineering standards, validation protocols, and material specifications for valvetrain systems.
Stay up-to-date with emerging valvetrain technologies and competitive benchmarking.

Dynamic and Durability Analysis
System-Level Integration and NVH Optimization
Timing System Design (Chain, Belt, Gears)
Production-Ready, Cost-Effective Design Solutions
Bachelor’s or Master’s in Mechanical Engineering, Automotive Engineering, or related field.
10–15+ years of experience in engine valvetrain development, with 5+ years in a technical leadership role.
Deep knowledge of camshaft design, valve actuation mechanisms, valve materials/coatings, and timing system architecture.
Proficiency in CAD (Creo, CATIA), CAE (ANSYS, AVL Excite, GT-VTD, Ricardo Valdyn), and fatigue simulation tools.
Experience in both high-volume manufacturing and performance/low-volume engine programs.
Strong communication skills and ability to lead technical reviews with global engineering teams or OEM clients.
