Engine Design Engineer

Role Overview

We are looking for an Engine Design Engineer with strong fundamentals in powertrain component design and hands-on experience in cranktrain, valvetrain, and transmission sub-assemblies. The role involves detailed 3D modelling, assembly design, engineering calculations, and releasing drawings through PLM systems. The ideal candidate should be capable of end-to-end design from concept, layout, tolerance analysis, to manufacturing support for engine and drivetrain components.

Key Responsibilities

1. Engine Component Sub-Assembly Design

• Design and develop crankshaft assemblies, including counterweight optimization, bearing selection, and balance considerations.
• Design camshaft assemblies, valve train layout, timing drive systems, and associated kinematics.
• Create detailed models of gearbox assemblies, including shafts, gears, synchronizers (if applicable), and housings.
• Develop differential assemblies, gear sets, carriers, and load-bearing components.
• Design gear selector mechanisms, shift forks, detents, and selector shafts ensuring smooth shifting and ergonomic feel.

2. Engineering Documentation Drawings

• Prepare detailed 2D engineering drawings with GDT, surface finish, tolerances, and critical-to-quality features.
• Perform tolerance stack-up studies to ensure manufacturability and assembly reliability.
• Release engineering deliverables through PLM (Windchill/Teamcenter/Enovia or equivalent).

3. Design Analysis Calculations

• Perform design calculations for:
  • Shaft strength and deflection
  • Bearing life and selection
  • Gear tooth bending/contact stress
  • Cam profile and valve timing requirements
  • Lubrication flow considerations
• Support basic FEA/strength analysis in collaboration with CAE teams.

4. Cross-Functional Collaboration

• Work with manufacturing, testing, and quality teams to ensure design feasibility, cost optimization, and robustness.
• Support prototype engine builds, validation testing, and troubleshooting for design improvements.

5. Continuous Improvement

• Implement design standardization, modularization, and reuse of platforms for new engine and transmission variants.
• Contribute to DFMEA and design review processes.

Required Technical Skills

• Expertise in 3D CAD tools (Creo/SolidWorks/Catia).
• Strong fundamentals in the design of:
  • Crankshaft assembly
  • Camshaft/valvetrain
  • Gearbox
  • Differential
  • Gear selector mechanism
• Good understanding of engineering drawings, GDT, tolerance stack-up.
• Knowledge of PLM systems.
• Familiarity with design calculations related to powertrain components.

Soft Skills

• Strong problem-solving and engineering judgement.
• Ability to work with cross-functional teams.
• Good communication, documentation, and presentation skills.
• Ownership, attention to detail, and time management.

Qualifications

• B.E./B.Tech. in Mechanical/Automobile Engineering.
• Knowledge of engine fundamentals and powertrain architecture is essential.
• Experience with 2W/3W/4W engine design is an added advantage.
