PhysicsX is a deep-tech company focused on accelerating hardware innovation through AI-driven simulation software. The Simulation Engineer - FEA will apply finite element analysis to engineering challenges, work with customers to build CAE models, and contribute to high-fidelity simulations across industries.
Responsibilities
- Assist in building complex structural and multi-physics models from geometry clean-up and meshing, to simulating and post-processing complex real-world phenomena, integrating experimental data for model validation
- Building robust parametric CAD models (NX or CATIA) coupled with simulation pipeline automation through scripting, for executing advanced design optimization and DoE studies
- Partner with customers to address their most complex engineering challenges through advanced FEA & AI solutions; communicate results clearly
- Working at the intersection of CAE and Data Science to generate high-quality simulation datasets for training Machine/Deep Learning models. Leveraging data sampling techniques to efficiently capture the design space, reduce computational cost, and enhance model accuracy
- Accelerate high-fidelity modelling by using Flux (our cloud platform) and on-premise HPC resources, going beyond smart meshing and model setup to achieve real performance gains
- Document your work through clear technical reports and process notes, contributing to the team's shared knowledge base
- Traveling domestically and globally (North America, Europe, Asia, Oceania) up to 3-4 weeks per quarter to work side-by-side with customers in building solutions on-site
Skills
- Hands-on experience applying finite element analysis to real-world engineering challenges across multiple industries including aerospace and defense
- Expertise in structural mechanics and materials science
- Solid ability to apply fundamental knowledge to real-world phenomena across a wide range of engineering applications
- Highly proficient in at least one of NASTRAN, ABAQUS or ANSYS Mechanical
- Adept at automating these tools to create scalable optimisation workflows
- 1-2 years of industry experience (post Masters or PhD) in a commercial, non-research environment
- Confident setting up FEA simulations independently
- Ability to interpret complex results with depth
- Making informed decisions based on solid engineering judgement
- Familiarity with turbomachinery analysis, gas turbine, or aircraft structural sizing
- Background in composite materials analysis
- Some exposure to damage tolerance and fracture mechanics
- Exposure to open-source FEA tools (CalculiX, FEniCS) or explicit dynamics (LS-DYNA, Abaqus/Explicit)
- Proficiency in parametric CAD modelling (NX or CATIA)
- Coding in Python, or the ability to quickly learn programming languages
- Experience with multidisciplinary optimization (MDO)
