Applied AI Engineer

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
