About the role

Fundamental AI research lab building the world’s most powerful Large Tabular Model for enterprise decision-making. Opportunity to work on foundation model development, productionizing capabilities, and optimizing ML systems for tabular data.

Responsibilities

  • Take part in development and optimization of a large neural network-based tabular model implemented in Python
  • Profile training and inference pipelines to identify performance bottlenecks
  • Rewrite critical components in Rust (via PyO3 or custom extensions) where Python limits us, with C++ (via PyBind11 or custom extensions) as a secondary option where appropriate
  • Improve memory efficiency, latency, and throughput across model pipelines
  • Ensure correctness, numerical stability, and reproducibility as the model evolves
  • Collaborate with ML researchers on productionizing new capabilities
  • Maintain clean abstractions, comprehensive tests, and clear documentation
  • Shape architectural decisions for our ML systems handling tabular data

Qualifications

  • Strong software engineering fundamentals with expert-level Python and Rust
  • Hands-on experience bridging Python and Rust (PyO3, maturin, or custom extensions)
  • Experience developing and maintaining ML models in production
  • Strong understanding of neural networks
  • Track record of optimizing performance-critical code
  • Strong profiling and debugging skills (CPU, memory, latency)

Skills

Required:PythonRustML in production
Nice to have:C++

Benefits

  • Competitive compensation with salary and equity
  • Comprehensive health coverage for you and your dependents
  • Paid parental leave for all new parents, inclusive of adoptive and surrogate journeys
