Principal Data & Applied Scientist

Microsoft - Melbourne, VIC

Source: uWorkin


Do you have a passion for Data and Machine Learning? Do you dream of working with customers on their most forward-looking AI initiatives? Does developing modern machine learning solutions to solve real-world business problems in the cloud sound exciting to you? You may be the Principal Data & Applied Scientist we have been looking for!

The Commercial Software Engineering (CSE) team is a global engineering organization that works directly with customers looking to leverage the latest technologies to address their toughest problems and transform their industries using cloud-based solutions. We sit side-by-side with our customers to collaboratively innovate custom solutions tailored to their business needs. In the process, we help shape the future of our own platforms by partnering with our product groups to improve them. We pride ourselves on making contributions to open source and make our platforms easier to adopt. Our work involves the development of high-impact software assets that contribute to the Microsoft platform that are broadly applicable.

We are looking for a Principal Data Scientist with strong analytical and development skills to join our expanding team. The ideal candidate has extensive expertise in machine learning and is passionate about creating business value through building robust and performant cloud-based solutions infused with AI. They should be comfortable with the end-to-end ML/AI solutions development process, starting from understanding the customer business problem and ending with production implementation of machine learning pipelines. Don’t worry, we will never ask you to implement the entire ML system all by yourself. We will, however, expect you to be able to contribute to any of its parts. We don’t develop awesome models to see them wilt and die in a Jupyter notebook on someone’s laptop. Instead, we nurture them into production via a fully reproducible continuous delivery process reinforced by a battery of full lifecycle tests. If you’re the type of person who likes both the science and engineering aspects of machine learning, we want to talk to you!

As a group, we work to build consensus with our teammates and customers. We’re looking for the sort of person who enjoys a culture that ensures that all voices and perspectives are heard and considered. Above all we want you to be inspired, and inspire others, by the potential of the future. If you want to chat informally about the role, please reach out to us.
