Responsibilities
Solver Formulation: Derive and implement governing equations for structural mechanics, ensuring thermodynamic consistency and physical accuracy across linear and non-linear regimes
Numerical Architecture: Design the core numerical framework. You will determine the optimal discretization strategies (FEM, DG, IGA, etc.) to balance stability, accuracy, and computational cost
Algorithmic Development: Specific language is secondary to code quality. You will write clean, modular, and efficient algorithms to solve large-scale systems of equations
Physics-Driven Validation: Diagnose solver behavior not just as code execution, but as physical modeling. You must distinguish between numerical instability and physical phenomena
Qualification
Required
Ph.D. in Applied Mechanics, Physics, Applied Mathematics, or a related field
You possess an intuitive grasp of continuum mechanics—elasticity, plasticity, contact mechanics, and wave propagation. You can predict how a structure should behave before the simulation runs
You have a theoretical mastery of numerical PDEs. You can mathematically prove the consistency, stability, and convergence of a scheme. You understand the trade-offs between implicit/explicit integration and various spatial discretizations
Proficiency in at least one high-level language (C++, Python, Julia, Rust, or Fortran) with a focus on algorithmic efficiency. You understand data structures, computational complexity (Big O), and how to write maintainable research code
Demonstrated ability to solve novel problems where no textbook solution exists
Preferred
Interest in learning High-Performance Computing (HPC) and GPU architecture
Experience with C++ for scientific computing
Exposure to multi-physics coupling (fluid-structure interaction, thermal-stress)
Benefits
Comprehensive Medical, Dental, and Vision insurance
401(k)
Gym/fitness allowance
