Member of Technical Staff - Research Software Engineer

Reflection AI is on a mission to build open superintelligence and make it accessible to all. They are seeking a Research Software Engineer to bridge the gap between research and production by designing and optimizing the core infrastructure for training frontier AI models.

Responsibilities:

• Designing and optimizing large-scale training loops and data pipelines
• Implementing state-of-the-art techniques and ensuring they are numerically stable and computationally efficient
• Building internal tooling for launching, monitoring, and reproducing complex experiments
• Diagnosing deep bottlenecks across the training stack (GPU memory issues, communication overhead, dataloader stalls)
• Translating research prototypes into reusable, production-grade infrastructure
