Member of Technical Staff, AI - Post-Training

Help us develop and train the cutting-edge models that are served in Copilot. 

At Microsoft AI, we are on a mission to develop the most cutting-edge algorithms for post-training large language models (LLMs) and ship those models to millions of users using Copilot every day.   

The AI Post-Training team at Microsoft AI is responsible for all aspects of post-training the models that we serve in Copilot, including: data collection, building evaluations that are aligned with our product and model capability goals, prototyping new capabilities to make Copilot more powerful, developing new fine-tuning algorithms to supercharge our models, working with platform and engineering teams to deploy those models, and closing the loop by improving the models with feedback we receive from our users. We work on the bleeding edge and leverage the most powerful pretrained models and algorithms for our needs. We are an interdisciplinary team of engineers and scientists, learning from each other and collaborating to create the best models and products.  

We are looking for outstanding individuals excited about contributing to the next generation of models that will transform the field. We are looking for candidates who:  

• Are passionate about shipping models into products that users will love  
• Will thrive in a highly collaborative, fast-paced environment.  
• Have a high degree of craftsmanship and pay close attention to details.  
• Demonstrate a proactive attitude and enthusiasm for exploring new methods and technologies.  
• Are willing to meaningfully contribute as individuals with multiple responsibilities and can adjust to shifting priorities. 

Microsoft’s mission is to empower every person and every organization on the planet to achieve more. As employees we come together with a growth mindset, innovate to empower others, and collaborate to realize our shared goals. Each day we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond.

Responsibilities

• Develop data collection, evaluation, and fine-tuning methods for models.  
• Design hypotheses and experiment plans for rapidly iterating on model performance.  
• Prototype new model features and capabilities and collaborate with engineers and researchers across Microsoft AI to make them a reality.  
• Collaborate with pretraining and product platform teams to establish good vertical integration and ship models that Copilot users love.  
• Embody our culture and values.
