Microsoft AI is looking for a Member of Technical Staff – Reinforcement Learning Systems to help build the world’s most advanced reinforcement learning systems. We are responsible for designing, developing, and operating the large-scale reinforcement learning systems that power several use cases – from training trustworthy and capable agents and powerful reasoning models to helpful and conversational assistants.
We are looking for individuals who can contribute to cutting-edge research and help bridge the gap between cutting-edge research and robust, production-grade distributed systems. The ideal candidate has both distributed systems expertise and a scientific mindset and will be able to build complex and scalable systems from the ground up, identify and resolve performance bottlenecks, debug complex, cross-system issues with extremely high attention to detail, and contribute to solving scientific and research challenges. Specifically, they should:
Excel in programming (especially parallel/concurrent and distributed), software engineering, and system design
Have experience in large-scale systems, preferably having built some components from scratch.
Thrive in a highly collaborative, fast-paced environment
Have a high degree of craftsmanship and pay close attention to details
Effectively manage multiple responsibilities and can adjust to shifting priorities
A background in machine learning is preferred but not required. In this case, candidates must demonstrate they have an ability to quickly learn the subject, and backgrounds in mathematics, competitive programming, and related domains are a plus.
