We are seeking an ambitious Mechanical Design & Simulation Engineer to join our core engineering team in Bengaluru. In this role, you will lead the end-to-end mechanical design, structural/thermal simulation, and prototyping of next-generation Lithium-ion (Li-ion) battery packs and enclosures. Responsibilities
- Mechanical CAD Design: Prepare 3D designs and assemblies for Li-ion battery pack components using SolidWorks —including plastic enclosures, sheet metal brackets, die-cast parts, busbars, insulation sheets, sealing mechanisms, and testing JIGs.
- Simulation & FEA Analysis: Conduct multi-physics FEA and CFD simulations including Vibration (Random & Sweep), Mechanical Shock, Thermal Shock, Resonance, Static FEA, Crush Analysis, and CFD.
- Design Optimization: Interpret simulation results to provide actionable design improvements, lightweighting, and thermal/structural optimization.
- Manufacturing & Drawings: Generate detailed 2D manufacturing drawings, apply GD&T; , perform tolerance stack-up studies, and ensure creepage & clearance compliance.
- DFM / DFA Implementation: Apply Design for Manufacturing (DFM) and Design for Assembly (DFA) principles across plastic injection molding, sheet metal stamping, and die-casting.
- Testing & Validation:



Review test plans, build testing JIGs, and collaborate with validation teams to evaluate battery component performance under operational stresses.
- Effort & Planning: Support project timelines with accurate effort estimation for mechanical design and simulation deliverables. Qualifications
-

Education:
BE / B.
Tech in Mechanical Engineering (Mandatory).
-

Experience:
1 to 5 years in mechanical design, preferably with direct exposure to Li-ion battery packs, EV battery systems, or BESS .
- CAD Expertise: Advanced proficiency in SolidWorks (3D modeling, sheet metal, plastics, 2D drafting).
- FEA / Simulation Expertise: Strong hands-on experience in FEA/CFD simulation using ANSYS or Abaqus (Knowledge of Star-CCM+ or COMSOL is a robust plus).
- Domain Knowledge:
- Solid understanding of plastic materials, sheet metal forming, and die-casting processes.
- Practical knowledge of material selection based on thermal, mechanical, and electrical properties.
- Strong foundation in GD&T; , tolerance stack-up, DFM, and DFA.
-

Location:
Based in or willing to relocate to Bengaluru (5 days Work From Office).
