Fundamental jobs

Fundamental, an AI company founded by DeepMind alumni, is hiring a Machine Learning Systems Engineer to join the team building NEXUS, a large tabular model for enterprise decision-making. The role involves developing and optimizing a Python-based neural network for tabular data, profiling pipelines to identify bottlenecks, and rewriting critical components in Rust and C++ to overcome Python's performance limitations. You'll need expert-level Python and Rust with proven hands-on experience bridging the two (PyO3/maturin), working C++ proficiency, production ML experience, and strong skills in performance optimization and debugging across CPU, memory, and latency. The company is backed by top-tier investors, trusted by Fortune 100 companies, and offers competitive salary plus equity with comprehensive benefits including relocation support. This is a systems-heavy role—the deal-breaker requirement is expert Rust skills with demonstrated PyO3/custom extension work; generic Python or ML backgrounds won't suffice without the deep systems programming chops in Rust.
