The opportunity
Crusoe is on a mission to accelerate the abundance of energy and intelligence . As the only vertically integrated AI infrastructure company built from the ground up, we own and operate each layer of the stack — from electrons to tokens — to power the world's most ambitious AI workloads.
What you'll do
Manage fine-tuning systems for large foundation models (SFT, PEFT, LoRA,: adapters), including multi-node orchestration, checkpointing, failure recovery, and cost-efficient scaling.
Implement and maintain end-to-end training pipelines for Large Language Models.
RFT and Reinforcement learning to the fine tuning and training sections
Distillation and reinforcement learning pipelines (e.g., preference: optimization, policy optimization, reward modeling).
Dataset, model, and experiment management: versioning, lineage, evaluation, and reproducible fine-tuning at scale.
Advanced degree in Computer Science, Engineering, or a related field.
What they're looking for
- + years of industry experience leading and driving impactful projects in the AI Space
- Experience in Generative AI (Large Language Models, Multimodal).
- Hands-on experience training, fine-tuning, and aligning LLMs using: Reinforcement Learning and Reinforcement Fine-Tuning (RFT) techniques.
- Proactive and collaborative approach with the ability to work autonomously
