Member of Technical Staff — LLM Research & Training

About the Role

We are looking for an exceptional Member of Technical Staff specializing in Machine Learning and Large Language Models to join an early-stage AI company building and training state-of-the-art foundation models.

This role sits at the intersection of LLM research, large-scale training infrastructure, post-training, and GPU/kernel optimization.

We are particularly interested in highly motivated researchers and engineers who want to contribute directly to training powerful models — whether their strengths are in theoretical model research, training systems, distributed infrastructure, or low-level performance optimization.

You will work in a small, highly technical team where researchers and engineers collaborate closely and are expected to take ownership across the stack.

Responsibilities

• Research, design, and implement new techniques for training and improving large language models.

• Build and optimize large-scale pre-training and post-training pipelines.

• Improve model training efficiency, throughput, stability, and scalability.

• Work on distributed trai
