About the job

Requirements
  • A Ph.D. in Computer Science, Artificial Intelligence, Machine Learning, or a closely related field.
  • A strong publication record in top-tier conferences such as NeurIPS, ICML, or ICLR, focused on reinforcement learning, alignment, or generative models.
  • Extensive experience implementing and optimizing large-scale training pipelines using PyTorch.
  • Deep understanding of reinforcement learning techniques, particularly reinforcement learning from human feedback.
  • Experience with distributed training systems and large-scale experiments.
  • A proven track record designing and implementing robust evaluation frameworks.
  • Strong software engineering skills and experience with complex shared codebases.
Responsibilities
  • Lead research initiatives in alignment and post-training methods for video generation models, focusing on improved quality, reliability, and adherence to human intent.
  • Design and implement supervised fine-tuning and reinforcement learning from human feedback pipelines for video generation models.
  • Develop robust evaluation frameworks to measure model alignment, safety, and output quality.
  • Create and optimize data collection pipelines for human feedback and preferences.
  • Design and conduct experiments to validate alignment techniques and their scaling properties.
  • Collaborate with cross-functional teams to integrate alignment improvements into the production pipeline.
  • Regularly review academic literature in generative artificial intelligence and alignment.
  • Mentor junior researchers and foster a culture of responsible artificial intelligence development.
  • Work closely with product teams to ensure alignment methods enhance rather than inhibit model capabilities.
Desired Qualifications
  • Experience with diffusion models or other generative architectures.
  • A background in fine-tuning large language models or generative models.
  • Experience working with human feedback data collection and annotation pipelines.
  • A strong aesthetic sense and understanding of video quality assessment.
  • Familiarity with alignment techniques such as constitutional artificial intelligence or debate.
  • A track record of successful collaboration with product teams.
  • Experience with perceptual quality metrics and human evaluation design.
  • Contributions to open-source projects in artificial intelligence alignment or generative artificial intelligence.

Simplify's Take

What believers are saying

  • Genmo.ai still promoted Mochi 1 on August 25, 2026, showing active distribution.
  • The free playground and Apache license lower adoption friction for creators and developers.
  • NEA led Genmo's $30 million Series A on October 22, 2024, funding compute and hiring.

What critics are saying

  • Wan 2.2 and MiniMax-H3 outclass Mochi 1 by August 2026.
  • Genmo still ships only Mochi 1, and that preview remains 480p.
  • Open-source rivals erase pricing power and can make Genmo a commodity layer.

What makes Genmo unique

  • Genmo released Mochi 1 on September 10, 2025 under Apache 2.0.
  • Mochi 1 used a 10-billion-parameter Asymmetric Diffusion Transformer for text-to-video.
  • Genmo pairs open weights, GitHub, Hugging Face, and a free playground.
