Simulation Software Engineer — Digital Twin & HPC

Build the compute substrate and software behind the twin — from HPC pipelines to the interactive open model.

About the role

Kronos runs on software: reproducible simulation pipelines, an HPC/GPU training substrate, a data fabric, and the public, explorable model. You'll build the systems that let physicists and engineers move fast and verify everything.

What you'll do

• Build reproducible simulation and data pipelines feeding the twin.
• Optimize HPC/GPU workloads for multi-physics and model training.
• Engineer the data fabric, feature store, and provenance/versioning.
• Ship the open, public-facing model and developer tools.
• Harden reproducibility (cold-repro runbooks, environment pinning).
• Partner with physics, controls, and materials teams.

What you bring

• Strong software engineering with scientific/HPC computing experience.
• Python plus performance-minded systems skills.
• Familiarity with GPU compute, containers, and CI.
• An open-source, reproducible-by-default mindset.
• Bonus: simulation, visualization, or digital-twin experience.
