Software Engineer, Finite Element Analysis & Structural Optimization

## About the role Full-time | Hybrid (LA / Orange County) or Remote ## About InfinitForm InfinitForm is building the Physical AI platform for engineering teams. We help manufacturers generate production-ready designs dramatically faster by bringing simulation, optimization, manufacturability constraints, and editable parametric CAD into one workflow. Today, engineering teams often spend months moving from concept to validated, manufacturable design. InfinitForm compresses that cycle from months to days — helping teams explore more design options, reduce late-stage rework, and bring better physical products to production faster. Our platform is designed for aerospace, automotive, defense, robotics, and advanced manufacturing companies operating at the frontier of physical product development. Backed by leading investors and built by pioneers in computational geometry, simulation, and advanced manufacturing, InfinitForm is defining a new category at the intersection of AI and engineering. ## The Role We're looking for a skilled and driven Finite Element Analysis & Structural Optimization Engineer to join our core engineering team. The seniority level for this role is flexible. You'll work at the intersection of computational mechanics, simulation, optimization, and AI-native engineering workflows — helping build the core simulation and optimization infrastructure behind InfinitForm's platform. This is a deeply technical, hands-on role focused on building high-performance systems for structural simulation and generative engineering. Your work will directly shape the algorithms and solvers powering a new generation of engineering software for the physical world. You'll collaborate closely with researchers, computational engineers, geometry engineers, and product teams working on complex real-world problems across aerospace, automotive, defense, robotics, and industrial manufacturing. ## What You'll Do - Simulation & Solver Development - Design, implement, and optimize finite element analysis (FEA) solvers and structural simulation pipelines - Develop high-performance simulation infrastructure for large-scale engineering optimization workflows - Improve solver stability, accuracy, scalability, and runtime performance - Build production-quality numerical software in C++ for scientific and engineering computation - Contribute to GPU-accelerated simulation and optimization systems - Structural Optimization & Research - Develop structural optimization algorithms including topology, shape, and sizing optimization - Work on sensitivity analysis, constraint handling, and optimization methodologies - Explore new approaches to simulation-aware and manufacturability-aware optimization - Contribute to research-oriented problem solving across engineering and computational geometry domains - Help bridge optimization outputs into production-ready CAD workflows - Technical Collaboration - Collaborate closely with Product, Research, and Application Engineering teams - Participate in technical arc
