What are the responsibilities and job description for the ML Engineer position at Fundamental Research Labs?
About The Role
As a Machine Learning Engineer, you’ll push the frontier of post-training for large language models from supervised fine-tuning to advanced reinforcement learning to train powerful agents capable of complex, end-to-end reasoning and action.
You’ll work side-by-side with our researchers to rapidly iterate on alignment strategies, implement state-of-the-art training algorithms, and run large-scale experiments that directly improve our production models.
If you love making models smarter, safer, and more capable, and want to work at the cutting edge of LLM agent training, this role is for you.
