About the job

We are building a platform that covers the entire lifecycle of Large Language Models (LLMs), from training to deployment and production observation. Our existing infrastructure supports multi-node training, elastic inference, sandboxes, and distributed volumes, with full control over the underlying systems. We are seeking individuals with deep research expertise in post-training techniques to complement our existing systems and product development efforts. This role is ideal for candidates passionate about improving current methods and creating novel techniques for large-scale model training, optimization, and inference. You will focus on extending models to handle long-context and long-horizon tasks, and enhancing inference-time efficiency, reliability, and robustness for critical real-world applications.

Responsibilities

  • Improve existing methods and develop new techniques for large-scale model training, optimization, and inference.
  • Extend models to handle long-context and long-horizon tasks.
  • Improve inference-time efficiency, reliability, and robustness in high-stakes real-world deployments.

Requirements

  • PhD in computer science, machine learning, or a related field (or Master's degree with significant research/industry experience).
  • Demonstrated record of research accomplishments in reinforcement learning, machine learning, foundation models, or related fields.
  • Experience with large-scale training and inference infrastructure, including distributed systems and multi-node GPU clusters.
  • Experience developing, training, optimizing, or deploying state-of-the-art large-scale models.
  • First-author publications at leading AI/ML venues (e.g., NeurIPS, ICML, ICLR, CoRL, CVPR, UAI, JMLR, TMLR).
  • Mission-driven mindset and desire to translate research into product impact.
  • Collaborative spirit and ability to work effectively across research and engineering teams.
