Simulation Engineer - FEA

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) Benefits Equity options - share meaningfully in the company you’re helping to build. 5% contribution to 401(k) - build long-term security with a strong retirement plan. Free team lunch 1x/week - good food, great company, and space to connect. Private health insurance – comprehensive cover for you, offering total peace of mind. Enhanced parental leave – 3 months full pay paternity and 6 months full pay maternity leave, to provide extra flexibility during the moments that matter most. 20 days of Annual Leave (+ Public Holidays) - because taking time to rest matters. Personal development – dedicated support for learning, development, and leveling up over time. Gympass / Wellhub (subsidized) – for you and up to 3 family members, supporting both physical and mental wellbeing. Flexible Spending Account (FSA) – set aside pre-tax dollars for eligible healthcare expenses.
