Applied AI Engineer
Develop and optimize large neural network-based tabular models. Profile and rewrite performance-critical components in Rust and C++ to improve efficiency, latency, and throughput for enterprise AI systems.
About the job
Key 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
Must Have
- Strong software engineering fundamentals with expert-level Python and Rust
- Hands-on experience bridging Python and Rust (PyO3, maturin, or custom extensions)
- Working proficiency in C++ and experience bridging Python and C++ (PyBind11, Cython, 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)
Nice to Have
- Experience with tabular ML approaches (transformers, tree/NN hybrids, learned embeddings)
- Familiarity with PyTorch internals or writing custom ops (Rust or C++)
- Experience optimizing training loops, data pipelines, or inference engines
- Background in numerical computing or systems programming
- Exposure to large-scale ML infrastructure (distributed training, batching, caching)
- Experience with the Rust async ecosystem (tokio) or SIMD/parallelism crates (rayon, ndarray)
Benefits
- Competitive compensation with salary and equity
- Comprehensive health coverage, including medical, dental, vision, and 401K
- Paid parental leave for all new parents, inclusive of adoptive and surrogate journeys
- Relocation support for employees moving to join the team in one of our office locations
- A mission-driven, low-ego culture that values diversity of thought, ownership, and bias toward action
