OpenAI is looking for a Machine Learning Engineer to build and scale intelligent notification systems for ChatGPT that provide real value to users even when they are not actively on the product. This role is crucial for shaping how ChatGPT proactively and helpfully communicates with users by surfacing the right content, at the right time, through the right channel.
Requirements
- Have hands-on experience building and deploying ranking, recommendation, or personalization systems at scale.
- Have a deep understanding of machine learning and its applications, with exposure to LLMs and their integration into product experiences.
- Are experienced in experimentation, A/B testing, and analyzing impact on user behavior and business metrics.
- Are comfortable diving into large ML codebases, designing evaluations, and debugging complex modeling issues.
Responsibilities
- Design and build end-to-end ranking and recommendation systems for notifications, from modeling to evaluation and deployment.
- Apply and adapt LLMs to ranking problems, including prompt-based approaches and fine-tuning.
- Develop experiments to evaluate notification relevance, user value, and long-term impact, working closely with product, data science, and engineering teams.
- Collaborate with research teams to leverage the latest modeling techniques while balancing practical constraints of production systems.
- Build robust offline and online evaluations to measure system improvements and user outcomes.
- Contribute to the broader Growth ML stack and help set technical direction for intelligent user engagement systems.
Other
- This role will be central to shaping how ChatGPT communicates proactively and helpfully with users—surfacing the right content, at the right time, through the right channel.
- The ideal candidate has sharp product intuition.
- You should be comfortable operating across research and product boundaries: thinking from first principles, running rigorous experiments, and building scalable systems.
- Thrive in dynamic, fast-changing environments and can think from first principles to design elegant solutions.
- Have strong product intuition and can balance modeling sophistication with product impact.
