Research Scientist, Mid-training

About the Team

The Mid-training team does cross-cutting research, engineering, and execution, including activities classically associated with both pre-training and post-training. We improve OpenAI's flagship models, adding new capabilities and making them more efficient. Recent examples of artifacts with major contributions from our team include GPT4-Turbo and GPT-4o.

About the Role

The efficiency of our frontier model architectures is key to making today’s models and those of the future accessible. Step-change improvements to efficiency can unlock new interfaces, enable new applications, and impact the frontier itself.

Ideal candidates have a deep understanding of state-of-the art architectures, a sophisticated understanding of LLM inference, and a hands-on empirical approach. A strong grasp of hardware (e.g. GPU memory hierarchy) is a plus. Competency with profiling, low-level optimization, and kernel writing is also desired. A good fit for this role will be equally happy coming up with a creative breakthrough, investing in strengthening a baseline, designing an eval, debugging a thorny regression, or tracking down a bottleneck.

This role is based in London, UK. We use a hybrid work model of 3 days in the office per week and offer relocation assistance to new employees.

In this role, you will:

• Design, execute, and analyze experiments autonomously and collaboratively

• Study, debug, and optimize both model performance and computational performance

• Contribute to training and inference infrastructure

You might thrive in this role if you:

• Have experience landing contributions to major LLM training runs

• Can thoroughly evaluate and improve deep learning architectures in a self-directed fashion

• Are motivated by safely deploying LLMs in the real world

• Are well-versed in the state of the art transformer modifications for efficiency

Compensation, Benefits and Perks
This is a position with OpenAI UK Ltd., which controls the hiring and management of this position. Total compensation includes competitive salary, generous equity and benefits.

• Private medical insurance covering 100% of premiums for employees and their dependents

• Pension plan with 4% employer contribution

• 52 weeks maternity leave and 20 weeks parental leave

• Unlimited time off

• Annual learning & development stipend (£1,200 per year)
