Research, Post-Training

Полная занятостьОфис

Обязанности

  • 01Post-Training Recipe Development: Iterate on the full stack of datasets, training stages, and hyperparameters that determine model behavior
  • 02Evaluation Design and Integrity: Build evals that actually capture what matters
  • 03Deep Understanding: When training produces results that don't make sense, you dig until you understand why
  • 04Alignment and Agent Behavior: Apply and advance techniques like RLHF, RLAIF, and constitutional approaches to shape how agents reason, act, and collaborate with humans in long-horizon tasks
  • 05Scaling and Exploration: Measure how performance scales with data and compute, and develop new methodologies when existing ones hit ceilings

Требования

  • 01A track record of advancing ML systems through post-training, alignment, or related methods: RLHF, RLAIF, preference modeling, reward learning, or equivalent
  • 02Strong fundamentals in probability, statistics, and ML theory. The ability to look at experimental data and distinguish real effects from noise and bugs
  • 03Evidence of original contributions: publications at top venues, open-source impact, or equivalent industry results
  • 04Experience with large-scale distributed training and the debugging that comes with it
  • 05Systems-level thinking: not just model optimization, but understanding how training pipelines, data, and evaluation interact
  • 06Comfort with ambiguity and fast-moving research environments where priorities shift quickly

Условия

  • 01Small, highly selective team where research and product move together; prototypes reach real deployment quickly
  • 02Compute is not a constraint: large allocations with training jobs routinely running across thousands of GPUs from day one
  • 03The environment rewards speed, autonomy, and technical depth with minimal process overhead; this is one of the most competitive and fast-moving problems in AI
  • 04Everything needed to operate at frontier scale from day one
