Job description

Job Summary:
OpenAI is an AI research and deployment company dedicated to ensuring that general-purpose artificial intelligence benefits all of humanity. They are seeking an engineer to design and implement the dataset infrastructure that powers OpenAI’s next-generation training stack, collaborating with researchers to build efficient and standardized dataset interfaces.
Responsibilities:
• Design and maintain standardized dataset APIs, including for multimodal (MM) data that cannot fit in memory.
• Build proactive testing and scale validation pipelines for dataset loading at GPU scale.
• Collaborate with teammates to integrate datasets seamlessly into training and inference pipelines, ensuring smooth adoption and a great user experience.
• Document and maintain dataset interfaces so they are discoverable, consistent, and easy for other teams to adopt.
• Establish safeguards and validation systems to ensure datasets remain reproducible and unchanged once standardized.
• Debug and resolve performance bottlenecks in distributed dataset loading (e.g., straggler systems slowing global training).
• Provide visualization and inspection tools to surface errors, bugs, or bottlenecks in datasets.
Qualifications:
Required:
• Have strong engineering fundamentals with experience in distributed systems, data pipelines, or infrastructure.
• Have experience building APIs, modular code, and scalable abstractions, while recognizing that abstractions ultimately serve the users and UX is an important part of the abstractions design.
• Are comfortable debugging bottlenecks across large fleets of machines.
• Take pride in building infrastructure that 'just works,' and find joy in being the guardian of reliability and scale.
• Are collaborative, humble, and excited to own a foundational (if not glamorous) part of the ML stack.
Preferred:
• Have background knowledge in data math, probability, or distributed data theory.
• Have worked with GPU-scale distributed systems or dataset scaling for real-time data.
Company:
OpenAI is an AI research and deployment company that develops advanced AI models, including ChatGPT. It is a sub-organization of OpenAI Foundation. Founded in 2015, the company is headquartered in San Francisco, USA, with a team of 1001-5000 employees. The company is currently Late Stage.
