Member of Technical Staff, Model Training (infra & platform)

Job Title: Member of Technical Staff, Model Training (infra & platform) Job Type: Full-time Location: Remote The Role In this role, you will take technical ownership of the distributed systems and platforms that enable researchers to train increasingly capable models, execute large-scale experiments, and deploy specialized AI systems efficiently. You will work across distributed training, GPU infrastructure, inference optimization, simulation environments, and agent execution frameworks, making critical architectural decisions that directly influence research velocity and model performance. What You'll Do Architect, build, and scale shared infrastructure for supervised fine-tuning (SFT), reinforcement learning (RL), and on-policy distillation (OPD), supporting language, multimodal, and robotics workloads. Design distributed training and execution pipelines that coordinate GPU workers, rollout generation, teacher-model inference, reward computation, and simulation environments. Develop high-performance infrastructure for model training and inference, optimizing GPU utilization, memory management, communication, storage, and distributed execution. Build and evolve the core architecture of micro1 's agent ecosystem, including execution runtimes, tool interfaces, environment integrations, model registries, and serving APIs. Develop robust systems for experiment tracking, dataset and model versioning, checkpointing, fault recovery, and observability to improve research reprodu
