Arjun Gireesh

BIW Performance Engineer with 2 years of hands-on experience at Mahindra & Mahindra, delivering structural performance across 4 SUV programs. Specialised in crash, NVH, and durability evaluation, lightweighting strategy, and topology optimisation — contributing to a 6 kg mass reduction and the development of a novel proprietary structural component. Proficient in CATIA V5/V6, 3DEXPERIENCE, Altair Inspire, SimSolid, and ANSYS Discovery.

Experienced in closing the design–CAE–validation loop independently and benchmarking against 50+ global models using A2Mac1 and Caresoft.

Engineer – Body Systems (Performance) at Tech Mahindra – Deputed to Mahindra & Mahindra Ltd, Mahindra Research Valley (2024-08 – Present)

• Led crash, NVH, and durability performance evaluations for BIW and closure systems across 4 SUV programs, identifying structural failure modes and recommending design countermeasures
• Delivered 6 kg mass reduction across 4 SUV programs by optimising BIW panel geometry and closure reinforcement profiles, directly contributing to vehicle weight targets
• Owned end-to-end design, analysis, and validation of a novel structural plastic insert concept for BIW and closure systems, improving both crash energy absorption and NVH performance — details proprietary
• Designed and evaluated local BIW concepts using mesh-less simulation tools (SimSolid, Altair Inspire), significantly reducing design iteration cycle time for closures and structural panels
• Benchmarked 50+ global SUV models using A2Mac1 and Caresoft to define BIW design targets and identify lightweighting opportunities for upcoming vehicle programs
• Improved torsional and bending stiffness of SUV body structure through targeted reinforcements in A/B/C pillars, underbody rails, and wheelhouse zones, validated via beam-based FEA models
• Executed topology optimisation on door hinges, latches, and bracket reinforcements using Altair Inspire, achieving optimal strength-to-weight ratio while meeting packaging constraints
• Partnered with the local CAE team to simulate and evaluate multiple design iterations for BIW panels, reinforcements, and sealing paths, accelerating design closure across programs
• Coordinated material characterisation testing and correlated physical results with CAE models to improve simulation prediction accuracy for BIW structural performance
• Co-developed internal design guidelines covering NVH targets, BIW stiffness benchmarks, glass and seal performance, and closure feel quality for SUV platforms
• Worked on beam-based FEA models to evaluate underbody configuration, load distribution, and stiffness sensitivity across multiple design iterations
