Research Engineer

About the Role

Join an AI research team as a Research Engineer, turning experimental code into production-ready systems. You will build the shared infrastructure and post-training pipelines that help research projects scale while preserving experimental integrity.

What You'll Do

• Turn research prototypes into tested, reusable data generation, training, and evaluation pipelines.
• Build distributed experiment infrastructure for data loading, checkpointing, and collecting agent interactions.
• Profile workloads and improve GPU utilization, memory efficiency, and data throughput.
• Develop tests, experiment tracking, and debugging tools while ensuring changes preserve research results.
• Work with researchers to translate ideas into robust, maintainable software.

What We're Looking For

• Strong Python skills and hands-on experience with PyTorch, JAX, or a comparable machine learning framework.
• Experience building and debugging software for model training, inference, or large-scale data processing.
• Understanding of machine learning experiments and how data, numerical precision, and implementation choices affect results.
• Sound software engineering practices, including testing, profiling, version control, and documentation.
• Distributed training or data processing experience with tools such as PyTorch distributed, DeepSpeed, or Ray is valuable.
• Familiarity with model-serving, machine learning, or experiment tracking tools is a plus; reinforcement learning systems and multimodal datasets are also useful.
