About the Role

We are seeking a highly motivated AI / ML Engineer to join our team for a groundbreaking project on AI-assisted structural optimization and material selection for defense applications. In this role, you will work closely with internal AI / ML experts developing advanced AI workflows. This workflow integrates topology optimization, finite element analysis (FEA), materials selection, and manufacturability constraints to accelerate and automate the redesign of critical components for improved performance and cost efficiency. The ideal candidate combines hands-on experience with FEA and optimization tools with strong engineering judgement around materials and manufacturing feasibility.

Key Responsibilities

• Analyze and optimize vehicle components
• Perform finite element analysis (FEA) and topology optimization using tools such as Altair or ANSYS, and evaluate results in the context of material and manufacturing constraints
• Guide materials selection and substitution efforts for component redesign, using commercial alloy databases and engineering tradeoffs
• Support the integration of  AI / ML models with FEA and topology optimization workflows
• Evaluate and refine designs for manufacturability, considering traditional processes (e.g., casting, forging, welding)
• Provide knowledge on metals, metal alloys, their processing conditions, and manufacturing methods
• Document workflows, tools, and deliverables to support handoff and commercial readiness
• Participate in internal and client-facing meetings, presenting technical findings clearly and effectively
