ML Systems Engineer for SWE-Focused LLMs (On-site & Equity)

Cosine is building autonomous AI engineers that plan, write and ship code inside real development workflows. You will build environments in which models learn to write software, develop pipelines for training data, and run fine-tuning and RL workloads that shape model behavior.

This is a hands-on role at the intersection of ML and software engineering, requiring production-grade tooling, PyTorch, Docker/Kubernetes, and data-centric optimization.
