Job description

Job Summary:
River AI is dedicated to creating personal AI owned and shaped by individuals. They are looking for exceptional researchers to design and train foundation models that power their personal AI, focusing on deep learning architectures that continuously learn and personalize.
Responsibilities:
• Design, train, and evaluate novel foundation models optimized for reasoning, multimodal understanding, and extreme personalization.
• Pioneer research in continual learning, enabling models to adapt in real-time based on local user interaction without catastrophic forgetting.
• Develop advanced techniques for data efficiency, alignment (e.g., RLHF), and parameter-efficient fine-tuning (PEFT) targeting our bespoke personal hardware.
• Partner directly with the infrastructure team to rapidly scale and unblock experimental architectures across large compute clusters.
Qualifications:
Required:
• BS, MS, or Ph.D. in Computer Science, Machine Learning, Mathematics, or equivalent practical industry experience.
• Deep understanding of modern deep learning architectures (e.g., Transformers, diffusion models) and advanced training methodologies.
• Extensive hands-on experience with PyTorch or JAX, with a track record of writing clean, scalable code for model training.
• Proven ability to take open-ended research problems from mathematical formulation to working, scaled implementations.
• A highly collaborative mindset and a bias for action to push boundaries in a fast-paced environment.
Preferred:
• Track record of impactful publications at top-tier AI conferences (e.g., NeurIPS, ICLR, ICML) or equivalent industry research breakthroughs.
• Specific expertise in continual learning, reinforcement learning, or optimizing models for edge/on-device inference.
• Experience pre-training or aligning frontier-scale language or multimodal models.
Company:
River AI provides an API for fine-tuning and reinforcement learning, enabling users to build and serve personalized AI models. Founded in 2026, the company is headquartered in Palo Alto, USA, with a team of 11-50 employees. The company is currently Early Stage.
