Principal Systems Developer – Kernel

The InterSystems IRIS data platform is the engine behind some of the world’s most important applications. At its core is a super scalable, high performance database engine built to naturally and flexibly store data accessed from multiple data models, including multi-dimensional arrays, key/value, relational tables, and objects. The database engine runs on a variety of operating systems including Linux, AIX and Windows. It’s designed to scale on large NUMA machines, distributed cache clusters, and the cloud.

The database kernel team needs a creative and motivated developer to join them in designing, implementing and enhancing components of the database engine and its embedded programming language. As part of a small team at the center of the data platform, you can expect to make a large impact with a high degree of independence.
