At a glance

Highlights

  • Build ML components improving reconstruction quality, speed, and accuracy.
  • Collaborate on hybrid algorithms blending physics with learned priors.
  • Productionize models with monitoring, safe fallbacks, and verification tooling.

Ideal candidate

Applied ML engineer comfortable bridging research and production in imaging or physics-based domains, with strong evaluation discipline and a passion for robust, high-stakes systems.

Requirements

  • Strong applied ML experience with comfort in signal processing, imaging or adjacent domains
  • Ability to move fluidly between research prototypes and production-quality systems
  • Strong evaluation discipline: metrics, ablations, data leakage avoidance, and reproducibility
  • Demonstrated track record applying ML to physics-based or inverse problems via shipped projects or publications
  • Pragmatic production mindset with reproducible training/inference and safe deployment in high-stakes contexts
  • Background in computational physics or scientific computing
  • Experience with PINNs and Neural Operators for PDEs in ultrasound simulation and imaging
  • Experience in Agentic-SciML is a plus
  • Hands-on data curation from messy real-world sources, ground truth definition, and labeling/simulation pipelines
  • Background in data assimilation combining observations with physics-based models
