Company

hirify.global4d develops simulation software for thermal, fluid-flow, and structural-mechanics applications used by engineers.

What you will do

• Develop and tune nonlinear solvers for geometric and material nonlinearity in solid mechanics.
• Build iterative linear solvers and preconditioners for large sparse systems.
• Port and optimize solvers for GPU execution using CUDA, HIP, SYCL, or equivalent frameworks.
• Implement finite-element discretizations for structural and thermomechanical simulations.
• Profile and benchmark solver performance, identifying and removing bottlenecks.
• Contribute to version control, automated testing, CI/CD, and code review practices while collaborating with physicists, engineers, and software developers.

Requirements

• 3–6 years of industry or research experience in computational mechanics, scientific computing, computational physics, numerical simulation, or HPC.
• Hands-on experience with geometric and material nonlinearity, large-deformation kinematics, nonlinear constitutive models, and Newton-type methods.
• Strong foundation in the finite element method for solid and structural mechanics.
• Experience implementing iterative linear solvers and preconditioning techniques for large sparse systems.
• Proven GPU programming experience and proficiency in C++ and/or Python.
• Strong software engineering practices, including Git, automated testing, CI/CD, and code review.

Nice to have

• Experience with warpage and residual-stress problems in semiconductor manufacturing.
• Familiarity with matrix-free methods, geometric multigrid, adaptive mesh refinement, or embedded geometry methods.
• Experience applying machine learning to solid mechanics.
• Experience with Nsight, VTune, or Roofline performance analysis.

Culture & Benefits

• Work on technically challenging problems with engineering impact.
• Join a small, collaborative team where contributions are visible.
• Receive competitive compensation with equity participation.
• Work in a flexible environment and help build the software platform from the ground up.
