Company

hirify.global is an early-stage startup building operator intelligence infrastructure that accelerates hardware design validation using foundation models trained on structured physics data.

What you will do

• Leverage the hirify.global framework to develop novel applications for transient domain modeling, interactions, and dynamics.
• Experiment with temporal propagation schemas using both classical and learned approaches.
• Generate and curate training and verification samples using existing data infrastructure.
• Iterate on prototypes and harden features in collaboration with customers.
• Work cross-functionally with physicists, AI researchers, and computational geometry experts to deploy production-ready systems.

Requirements

• MS/MSc with 4+ years of experience or PhD with 2+ years of experience.
• 2+ years of experience building or using physics simulators (FEM, FEA, Molecular Dynamics, FDTD).
• Applied machine learning experience (Computer Vision, GraphNN, Transformer Architectures).
• Proficiency with PyTorch, Numpy, and Cuda.
• Experience contributing to production data processing systems and software design standards.
• Strong discipline in CI, regression testing, and validation.

Nice to have

• Experience applying ML to meshing geometry or accelerating FEM/DFT simulations.
• Background in moving early-stage prototypes to production environments at a startup or national lab.
• Experience leveraging simulation for design or data generation.

Culture & Benefits

• Opportunity to define a foundational abstraction layer in an early-stage, high-impact startup.
• Work directly with technical leadership including the CTO and CEO.
• Collaborative, small, and friendly team environment.
• Greenfield opportunities to architect large parts of the core system.
