TEAM INTRODUCTION: Target Data Sciences is revolutionizing the way Target retail uses data. Located in Sunnyvale, CA. Were just across the street from the local train station in the heart of Silicon Valley. Originally opened in 2014, the Sunnyvale office is now home to more than 200 team members who work to make Target AI and HPC a modern data-driven retail company!

The High-Performance Computing (HPC) team at Target has built products ranging from real-time data streaming to neural computing. We enable teams at Target to stream, filter, transform, and analyze high-bandwidth data in real-time, and also provide tools for data engineers and other team members to analyze and take action on their data. We also research the capabilities of next generation computer hardware, architectures, and algorithms in order to: build enterprise grade, efficient products and provide guidance on building scalable, fully utilized infrastructures.

Youll have the opportunity to work with a small team of HPC experts who have more 20 years of experience in the HPC domain. We play a critical role enabling Target to create cutting edge real-time data streaming and processing products which help to scale out critical deep learning infrastructures. As the Lead C++ Engineer of HPC, you will have the opportunity to create the vision for & drive the development of state-of-the-art high-performance computing systems for streaming data using modern C++ toolchains. This is a great opportunity for engineers with a passion for creating value by leveraging HPC to solve the most complex data science and engineering problems in retail.
